Top cybersecurity tools to use in your business
Implementing the appropriate cybersecurity tools is fundamental for organizations, becoming a strategic priority. In an environment where cyberattacks are becoming increasingly sophisticated and frequent, having a solid set of technological tools is essential for a company to be resilient rather than vulnerable.
This updated guide includes the main cybersecurity tools used in companies, what each one is for, and how to integrate them into an effective protection strategy.
Why is it essential for companies to implement cybersecurity tools?
Cybersecurity tools offer robust protection against various threats, enable early detection of risks and attacks, and enable proactive response to security incidents.
Threats and cyberattacks
Cybersecurity has become a top priority for businesses of all sizes. Cyberattacks are becoming more sophisticated and frequent, posing a significant threat to the integrity, availability, and confidentiality of corporate data.
Common threats include malware, ransomware, phishing, and denial-of-service (DDoS) attacks. The success of each of these attacks carries severe consequences, including the loss of critical data, disruptions to business operations, and damage to corporate reputation.
Malware, including viruses, worms, and Trojans, infiltrates company systems, corrupting files and stealing sensitive information. Ransomware is particularly dangerous because it encrypts company data and demands a ransom to release it.
Phishing attacks, conversely, use deceptive emails to obtain login credentials and other sensitive information from employees.
Finally, DDoS attacks can overwhelm company servers with malicious traffic, causing service disruptions and negatively impacting productivity.
Security risks in unprotected companies
Companies that lack sufficiently robust cybersecurity support tools are exposed to four critical risk categories:
- Data loss. Data is a company's most valuable asset. Its theft can be used for fraud, extortion, or corporate identity theft.
- Operational interruption. A ransomware attack can completely paralyze operations until the ransom is paid or the damage is reversed.
- Reputational damage. Security breaches erode the trust of customers, partners, and investors, directly impacting the bottom line.
- Regulatory sanctions. The GDPR in Europe, the DORA regulation for the financial sector, and other regulations require specific security measures, the non-compliance of which entails significant fines.
Consult our guide to the DORA regulation to learn about the cybersecurity requirements affecting the financial sector.
Top Cybersecurity tools to protect your business
Among the variety of cybersecurity support tools that an organization can implement to protect its systems, one group stands out for its effectiveness and efficiency:
Antivirus
Antivirus software is one of the most relevant and widely used cybersecurity tools. Its primary function is to detect, block, and remove malware before it can cause harm. Modern antivirus software uses advanced techniques such as signature-based detection, heuristics, and artificial intelligence to identify and neutralize a wide range of threats, including viruses, worms, Trojans, spyware, and ransomware.
- Signature-based detection. This technique uses a database of known malware signatures to identify threats. When antivirus software scans a file, it compares its signature to those in the database, and if it finds a match, it blocks and removes the threat.
- Heuristic. Heuristic methods enable antivirus software to identify suspicious behavior and code patterns that may indicate new or unknown malware. This technique is essential for detecting zero-day threats, which do not yet have known signatures.
- Artificial Intelligence and Machine Learning. Modern antivirus programs incorporate AI and machine learning technologies to improve real-time threat detection. These technologies can analyze large volumes of data and learn to identify malicious behavior patterns, even without a known signature.
Firewall
Firewalls are critical tools for cybersecurity. They act as a barrier between the company's internal network and external networks, such as the Internet. Their primary function is to control and filter incoming and outgoing network traffic, allowing only authorized connections and blocking unauthorized access.
- Hardware and software firewalls. Firewalls can be deployed as dedicated hardware appliances or software on servers and computers. Hardware firewalls are ideal for protecting the entire enterprise network, while software firewalls offer additional protection on individual devices.
- Packet Filters. Firewalls inspect every data packet entering or leaving the network, comparing it to predefined rules. If a packet complies with the rules, access is allowed. Otherwise, it is blocked.
- Next-Generation Firewalls (NGFW). NGFWs combine traditional firewall capabilities with advanced features such as deep packet inspection (DPI), intrusion prevention (IPS), and application-based threat protection.
Intrusion detection systems
Intrusion detection systems (IDS) and intrusion prevention systems (IPS) are essential tools for monitoring and protecting corporate networks against malicious activity. These systems analyze network traffic for behavioral patterns indicating an attempted intrusion or an ongoing attack.
- IDS (Intrusion Detection Systems). IDSs monitor network traffic in real-time and generate alerts when they detect suspicious activity. They can be passive, simply alerting security administrators, or active, automatically responding to threats.
- IPS (Intrusion Prevention Systems). IPS detects intrusions and takes steps to prevent them, such as blocking malicious traffic or applying additional firewall rules. IPS often integrates with other security systems to provide in-depth defense.
- Signature and behavior analysis.
IDS and IPS use signature analysis techniques to identify known threats and behavioral analysis to detect anomalous activity that could indicate new or unknown attacks.
Automated Cybersecurity Monitoring Tools
Automated monitoring is crucial to maintaining the security of corporate infrastructures. These tools allow businesses to continuously monitor their systems and networks for unusual or malicious activity and respond quickly to security incidents.
Security Information and Event Management Systems (SIEM)
SIEM solutions collect and analyze event data and logs from multiple sources on the enterprise network. They use advanced algorithms to detect suspicious behavior patterns and generate real-time alerts.
Incident Response and Analysis Tools
These tools allow security teams to quickly analyze security incidents and take the necessary steps to mitigate them. This can include identifying the incident's root cause, containing the threat, and recovering the affected system.
Cloud monitoring
Automated monitoring tools for cloud environments are essential with the increased use of cloud services. These tools monitor cloud activity, detect threats, and ensure compliance with company security policies.
Tools for Continuous Threat Exposure Management (CTEM)
To effectively protect their systems, organizations can't just manage the security of their internal infrastructure. Controlling exposed vulnerabilities that are available to anyone allows you to identify gaps and implement a proactive security strategy across the organization.
Continuous Threat Exposure Management (CTEM) solutions monitor the different layers of the web to locate those publicly exposed vulnerabilities, such as leaked data or credentials, and detect the open breaches that caused them.
The most advanced CTEM tools, such as Kartos, use technologies like Artificial Intelligence and Machine Learning to analyze and refine their data, providing highly accurate information about imminent threats.
Identity and access management tools
Identity and access management (IAM) is a crucial component of enterprise cybersecurity. IAM tools ensure that only authorized users can access critical business resources and data, and maintain strict controls over what users can do within the system.
- Multi-factor authentication (MFA). MFA adds an extra layer of security by requiring users to provide multiple forms of verification before accessing systems. This can include a combination of passwords, verification codes sent to mobile devices, fingerprints, or other biometric authentication methods.
- Privileged access management (PAM). PAM tools allow companies to control and monitor access management to privileged accounts, which have elevated permissions within the system. This includes implementing role-based access policies and logging all privileged account activities.
- Single Sign-On (SSO) Solutions. SSO allows users to access multiple applications and systems with a single login credential. This simplifies password management, improves the user experience, and provides centralized security controls.
Zero Trust cybersecurity tools
Today, the Zero Trust model has become a benchmark standard in corporate cybersecurity. Its principle is clear: do not trust any user, device, or system by default, whether inside or outside the corporate network.
The tools that underpin this architecture include network microsegmentation solutions, zero-trust network access, continuous identity management, and device verification. Their implementation reduces attackers' lateral movement after an initial breach, significantly limiting the impact of incidents.
Discover more about implementing the Zero Trust model in the corporate cybersecurity strategy.
How to choose the right cybersecurity tools for your company
There is no single optimal combination of cybersecurity tools. The selection should be based on a prior analysis of the organization that takes into account:
- Size and sector. SMEs have different needs and resources from large corporations or regulated sectors such as finance or healthcare.
- Attack surface. How many endpoints, remote users, cloud services, and third-party relationships does the organization manage?
- Cybersecurity maturity level.Whether the company is starting from scratch or seeking to reinforce an existing architecture.
- Regulatory requirements.GDPR, DORA, NIS2, or sector standards that require specific controls.
- Internal team capacity. The most advanced tools require specialized personnel for their management and analysis.

6 social media security strategies
Social media security has become a top concern for individuals, businesses, and institutions. With over 5.5 billion active users worldwide projected for 2026, social media platforms are a prime target for cybercriminals to steal data, impersonate others, and launch fraud campaigns. Understanding the importance of protecting your accounts and taking appropriate measures is no longer optional—it's essential.
In this article, we explain why privacy and security on social media are so critical, the consequences of ignoring them, and what social media security measures you can implement immediately to protect your personal information and digital reputation.
Importance of privacy and security in social networks
Social media has become integral to our lives, allowing us to connect with friends, family, and coworkers, share experiences, and access a wide range of content. However, as its use has increased, so has the amount of personal information we share online.
The threat landscape on social media has reached unprecedented levels. According to the Bitdefender Consumer Cybersecurity Report 2025 Social media has become the main channel for cyber scams, with 34% of reported cases originating from these platforms.
The importance of privacy and security on social media lies in the fact that these platforms act as gateways to our entire digital identity. A compromised account can lead to identity theft, extortion, harassment, or direct financial losses. Furthermore, reputational damage, for individuals, professionals, and brands alike, can be irreversible.
Social media and personal data security are intimately linked: every privacy setting we ignore, every third-party application we authorize without reviewing, and every weak password we use represent vulnerabilities that attackers can exploit.
Consequence of not protecting your social networks
Failing to implement social media security measures can have serious consequences. Some of the main ones are:
- Identity theft. Cybercriminals can obtain enough personal information from social media to impersonate the person and commit fraud. This can lead to opening credit accounts in your name, making fraudulent purchases, deceiving contacts, and many other malicious actions.
- Harassment and cyberbullying. A lack of privacy can expose users to harassment and cyberbullying. Attackers often use personal information shared on social media to harass their victims.
- Financial fraud. Personal and financial data shared on social media can be used to commit fraud. This includes accessing bank accounts, credit cards, and other financial services, as well as other actions likely to cause significant financial loss to the victim.
- Loss of reputation. Personal and professional information exposed on social media can be used to damage a person's reputation. This is especially detrimental to professionals who depend on their reputations for their careers.
- Unauthorized access to sensitive data. If not properly protected, social media accounts can be hacked, and sensitive data, such as private messages and photos, can be exposed and susceptible to malicious use.
- Exposure of third-party data. The personal information we share on social media not only affects us but can also expose the data of family members, friends, or co-workers who appear in our posts or contact lists.
6 Social Media Safety Measures
Implementing proactive security measures on social media is the only wayan effective way to minimize risks. Below, we detail the most important and up-to-date threats for the 2026 threat context.
Privacy settings on profiles
Privacy settings on social media profiles allow users to control who can view and access their information. Reviewing and adjusting these settings regularly ensures that only authorized people can see personal details.
- Limiting access to personal information: ensuring that only close contacts and family members can view it, such as location, marital status, and contact details.
- App Permissions Review: It is essential to be aware that third-party apps that connect to social media accounts may have access to sensitive personal data. Non-essential apps should be reviewed, and their permissions revoked.
- Post control: It's a good idea to set up your account so that only the owner can view and approve posts in which they are tagged. This will give you control over what appears on your profile.
- Disable search engine indexing: Most platforms allow you to prevent your profile from appearing in Google or other search engine results, thus reducing your public exposure.
Two-Factor Authentication
Two-factor authentication (2FA) is a security measure that protects social media accounts. Requiring a second form of verification in addition to the password, 2FA makes it harder for attackers to access an account, even if they know your password.
- 2FA implementation. Two-factor authentication must be enabled on all social media accounts. This usually involves receiving a verification code on the mobile phone or email.
- Authenticator apps. There are authenticator apps like Google Authenticator or Authy that generate temporary, one-time verification codes to access the account.
- Enable login notifications. Most platforms can send you an alert every time your account is accessed from a new device or location.
Secure password management
Strong, unique passwords are critical to protecting social media accounts. Reusing or using weak passwords significantly increases the risk of an account being hacked.
- Strong passwords. It would be best to create passwords that are difficult to guess, using a combination of upper- and lower-case letters, numbers, and special characters. Avoid using easily guessable personal information, such as names or dates of birth, and passwords that are common or repeated in other accounts.
- Password managers. Using a password manager to generate and store unique and strong passwords for each account is advisable. This makes password management easier and reduces the risk of reusing passwords.
- Periodic password changes. Although it is a routine that requires mental effort and attention to detail due to the number of accounts and passwords each person manages, it is essential to change passwords periodically and never share them with others or store them in places that are easy for others to access.
If you want to delve deeper into this topic, we recommend our post-> How to easily and securely manage business passwords and credentials to avoid online threats.
Always access from trusted devices
The devices you use to access your social media accounts are a critical link in the security chain. A compromised device can override any other protection measures.
- Avoid public or shared devices: Computers in libraries, hotels, or cafes may have keyloggers or other malware installed. If you use them only occasionally, always do so in incognito mode and log out when you're finished.
- Keep your devices updated: Operating system and application updates fix vulnerabilities that attackers actively exploit. Don't postpone them.
- Check the devices connected to your accounts: Most platforms display a list of devices that have recently accessed your account. Review it regularly and close any sessions you don't recognize.
AI-based threat recognition
The use of artificial intelligence by cybercriminals has led to significantly sophisticated attacks on social media. In 2026, it is crucial to understand emerging threats to avoid falling victim to them.
Deepfakes and identity theft
Attackers create hyper-realistic fake videos and images of trusted individuals to solicit personal information or money. If you encounter any unusual requests on social media, always verify them through another channel.
Hyper-personalized phishing
AI models analyze your social media activity to craft deceptive messages tailored to your profile, interests, and relationships. Be wary of urgent messages or those with suspicious links, even if they come from known contacts.
Bots and fake profiles
Disinformation and manipulation campaigns use armies of automated accounts to generate artificial trends or spread hoaxes. Before interacting with an unknown profile, check its age and activity.
Continuous cyber-surveillance of your profiles
The most innovative tools for cyber surveillance enable continuous monitoring of social media accounts and their online activity, allowing for quick detection and response to potential security threats, such as our Enthec solution. This helps prevent malicious or criminal use of both social media accounts and personal data.
The cyber surveillance system allows the user to configure alerts for suspicious activity. This way, you can receive real-time notifications about any suspicious activity on your social media accounts, such as login attempts from unknown locations or posts of unusual content.
Social networks and personal data security: an underestimated risk
The relationship between social networks and personal data security is more complex than it seems. Beyond the obvious risk of someone hacking your account, simply posting indiscriminately generates a digital trail that attackers can exploit to build detailed profiles of their victims, a technique known as OSINT.
The National Cybersecurity Institute warns that a large proportion of fraud and identity theft cases investigated in Spain originate from personal information voluntarily published on social media. Birth dates, pet names, workplaces, home photos, and even vacation schedules are data that cybercriminals use to create likely passwords, answer security questions, or design social engineering attacks.
To reduce your exposure, apply the principle of minimum disclosure: only share on social media things that you don't mind being in the public domain, and that cannot be used to identify you, locate you, or access your accounts.

How the DORA regulation impacts businesses and what steps you should take
If you work in the financial or technology sector, you have surely heard of an acronym that is keeping more than one IT director up at night: DORA.
DORA is the Digital Operational Resilience Act, one of the European Union's most ambitious and demanding cybersecurity regulations.
From January 2025, the DORA regulation is a mandatory reality. But why is it so important, and what will it really change for your business? It's not just another law; it's a shift in mindset. Having a good firewall is no longer enough; now, authorities want proof that your company can withstand a cyberattack and continue operating as if nothing happened.
What exactly is the DORA regulation, and which sector does it primarily target?
Although the name sounds general, which sector the DORA regulation primarily targets is one of the most frequently asked questions.
The short answer is: to the financial sector,. but the long answer is much more interesting. Unlike previous regulations that only targeted large banks, DORA extends to:
- Credit institutions and payment establishments.
- Investment and asset management companies.
- Insurance and reinsurance entities.
- ICT service providers that provide support to the above.
This last point is critical. If your company is a technology firm that sells software or cloud services to a bank, the DORA regulation also applies to you. The European Union has identified that the biggest weakness of the financial system is not always the bank itself, but rather the digital supply chain.
The pillars of the DORA regulation and cybersecurity
The aim of this regulation is to create a robust framework for the European financial system to withstand serious incidents. To achieve this, the DORA cybersecurity regulation rests on several fundamental pillars that companies must address:
1. ICT risk management
Organizations must have a solid governance framework. . Delegating security solely to the IT department is no longer permitted; company management is now legally responsible for risk decisions.
2. Incident Management and Reporting
If something happens, it must be reported. And quickly. The regulations establish strict deadlines and harmonized formats for reporting serious ICT incidents to the relevant authorities.
3. Digital operational resilience tests
This is where things get serious. DORA requires companies to conduct regular testing of their systems. For the most critical entities, this includes the TLPT (Threat-Led Penetration Testing), or penetration tests based on threat intelligence.
4. Third-party risk management
As we mentioned earlier, the DORA regulation focuses on your suppliers. You must audit how they manage their own security, since a breach in their system is, for all practical purposes, a breach in yours.
Analysis and guide to the DORA regulation: from compliance to strategy
If you look for analysis and guidance on the DORA regulation, you'll see that most experts agree on one thing: compliance cannot be reactive. Many companies make the mistake of waiting for an audit to find out whether their systems are up to date.
However, the current threat landscape doesn't wait. According to data from various European security reports, ransomware attacks and credential theft have increased exponentially in the last two years, particularly affecting financial services companies.
How to move from theory to practice?
To comply with the regulations, it is necessary to adopt tools that not only analyze risk once a year, but also offer a continuous overview. This is where the concept of CTEM, Continuous Threat Exposure Management, becomes vital.
Traditionally, companies would do a "pentesting"annually. The problem is that if a new vulnerability emerges the day after the test, your report is useless. A CTEM strategy proposes a five-stage cycle:
- Discovery of assets and attack surfaces.
- Mapping of possible attack routes.
- Prioritization based on real risk (not just technical).
- Validation that the controls work.
- Mobilization to correct what really matters.
How Kartos from Enthec helps you with compliance
At Enthec,we understand that managing all this information can be overwhelming. That's why we've developed solutions that align perfectly with the philosophy of the DORA regulation.
For companies seeking professional and continuous management, our Kartos platform is the answer. It positions itself as a key tool for CTEM, enabling organizations to automatically and non-intrusively monitor their external exposure.
- Third-party surveillance. One of the most challenging aspects of DORA is monitoring your suppliers. Kartos allows you to analyze the risk level of your supply chain without installing anything on their systems or requesting special permissions. You'll get a real and objective picture of their digital health.
- Leak detection. Kartos scans the Deep and Dark Web looking for leaked credentials or confidential information from your company before cybercriminals can use it.
- Risk scoring. It provides a clear score on your security posture, which greatly simplifies life for CISOs when reporting to the board of directors, as required by the new regulatory framework.
If you are a freelancer or concerned about your personal digital identity, we also have Qondar, our cyber-surveillance solution for individuals that applies the same principles of prevention and continuous monitoring.
Important: The DORA regulations are not just a checklist. They are an opportunity for your company to become more competitive and build greater trust with its customers.
Practical steps you should take today
If your company falls under the umbrella of this regulation (or if you simply want to improve your cybersecurity), here's a simple roadmap:
- Find out if you are affected. Check whether your activity, or that of your main clients, falls within the scope of the DORA regulation.
- Map your assets and suppliers. You can't protect what you don't know. You need an up-to-date inventory of all your systems and, above all, your critical IT providers.
- Adopt a CTEM mentality. Leave static audits behind. Implement continuous monitoring tools, such as Kartos, to have 24/7 visibility into your external attack surface.
- Review your contracts. Make sure that agreements with your technology service providers include the security and incident notification clauses required by law.
- Training and awareness. Human error remains the primary entry point. Train your team and, above all, raise management's awareness of their new legal responsibilities.
The DORA regulation may seem like a huge logistical challenge, but with the right tools and a proactive approach, it can become the best shield for your organization's future.
Are you worried about how the new regulations will affect your infrastructure or your suppliers?

What is data encryption: features and how does it work?
What is data encryption: features and how does it work?
Data encryption is a fundamental security practice to protect digital information and ensure its integrity and privacy. In a context where cyberattacks are growing in volume and sophistication, protecting data through encryption techniques is an unavoidable strategic and legal obligation for any organization.
However, encryption only works on data you already control. The critical question is: do you know if sensitive company information is exposed on the internet, the deep web, or the dark web without your knowledge? Cyber-surveillance platforms like Kartos, developed by Enthec, automatically monitor open vulnerabilities and data breaches affecting an organization in real time, including exposed databases and compromised credentials, thus complementing the layer of protection offered by encryption.
In this article, you will find a comprehensive guide, updated to 2026, on what data encryption is, how it works, the different types available, its main use cases, and how it relates to the GDPR and current regulations.
Data encryption: definition
Data encryption is the process of transforming readable information (plaintext) into an encoded format (ciphertext) that can only be read by those in possession of a specific decryption key. This process ensures that data is inaccessible to unauthorised persons, thus protecting the confidentiality and integrity of the information. Its importance lies in several key aspects that ensure data integrity, availability, and confidentiality:
- Privacy protection: Data encryption ensures that sensitive information, such as personal, financial, and health data, remains private and secure. By converting plaintext to ciphertext, only authorised persons with the decryption key can access the information.
- Communications security: In digital communications, such as emails, instant messages, and online transactions, encryption protects against interception and eavesdropping. By encrypting transmitted data, it ensures that any attempt to intercept the communication results in information that is unreadable to attackers.
- Compliance: Many regulations and laws, such as the General Data Protection Regulation (GDPR) in Europe, require encryption to protect personal data. Compliance with these regulations not only avoids legal sanctions but also demonstrates an organisation's commitment to protecting its customers‘ and users’ information.
- Cyber-attack and fraud prevention: Data encryption helps prevent unauthorised access and misuse of information, preventing the risk of fraud and cyber-attacks. Attackers attempting to access encrypted data will face a significant barrier, hindering their efforts and protecting critical information.
- Intellectual property protection: In the business environment, data encryption protects intellectual property such as trade secrets, patents, and confidential documents. This is essential to maintain a competitive advantage and prevent the leakage of valuable information.
- Customer trust: The use of database encryption also helps build trust among customers and users. Knowing that an organisation takes steps to protect its personal information increases customer trust and loyalty, which can translate into long-term business benefits.
Main challenges of data encryption
Despite its benefits, data encryption presents challenges:
- Key management. The generation, distribution, and secure storage of encryption keys are critical and complex.
- Rendimiento. El cifrado puede afectar el rendimiento de los sistemas, especialmente en el caso de cifrado asimétrico.
- Compatibility. It is necessary to ensure that systems and applications are compatible with the encryption methods used.
- Quantum threat. Advances in quantum computing put current encryption algorithms at risk. Cybercriminals are already employing the "harvest first, decrypt later" strategy: they store encrypted data today to decrypt it as soon as quantum computing becomes feasible, thereby jeopardizing long-term information such as trade secrets, medical research, and government documents. In response, NIST published the first official post-quantum cryptography standards (FIPS 203, 204, and 205) in 2024. The roadmap is clear: RSA and ECC asymmetric ciphers will become obsolete by 2030 and will be banned by 2035, making cryptographic migration planning essential now.
How data encryption works
The data encryption process is performed using mathematical algorithms and encryption keys. Database encryption algorithms are mathematical formulae that transform plaintext into ciphertext. The encryption process consists of the following steps:
- Key generation. An encryption key is generated, which will be used to transform the plaintext into ciphertext.
- Encryption. The encryption algorithm uses the key to convert plaintext into ciphertext.
- Transmission or storage. Ciphertext is transmitted or stored securely.
- Deciphered. The authorised receiver uses the corresponding key to convert the ciphertext back into plaintext.
Most effective techniques for data encryption
Keys are essential for data encryption and decryption. There are two main types of encryption:
- Symmetric Encryption: uses the same key to encrypt and decrypt data.
- Asymmetric Encryption: uses a public and a private key pair. The public key encrypts the data, and only the corresponding private key can decrypt it.
Each of these is explained in more detail below.
Symmetric encryption methods
Symmetric encryption is an encryption method that uses the same key to encrypt and decrypt data. It is known for its speed and efficiency, making it ideal for large volumes of data. Some of the most common methods include:
- AES (Estándar de cifrado avanzado). It is one of the most secure and widely used algorithms. It offers different key sizes (128, 192, and 256 bits) and is resistant to cryptographic attacks.
- DES (Data Encryption Standard). Although older and less secure than AES, it is still used in some applications. It uses a 56-bit key.
- 3DES (Triple DES). It improves the security of DES by applying the algorithm three times with two or three different keys.
Symmetric encryption is efficient, but secure key distribution is challenging because both parties must share the same key without compromising its security.
Asymmetric encryption methods
Asymmetric encryption uses a pair of keys: a public key and a private key. The public key is used to encrypt the data, while the corresponding private key is used to decrypt it. This method is more secure for data transmission, as the private key is never shared.
- RSA (Rivest-Shamir-Adleman). It is one of the best-known and most widely used asymmetric encryption algorithms. It provides high security and is used in applications such as digital signatures and SSL/TLS certificates.
- ECC (criptografía de curva elíptica). It uses elliptic curves to provide a high level of security with smaller keys, making it more efficient in terms of performance and resource usage.
Asymmetric encryption is ideal for secure data transmission, although it is slower than symmetric encryption due to its mathematical complexity.

Now that you know the examples of data encryption, it's time to discover its key benefits.
Key benefits of data encryption
Key benefits of database encryption include the following:
Data protection on different devices
Data encryption is an essential measure for protecting data on a variety of devices, including mobile phones, computers and servers. By converting information into a format unreadable to anyone without the decryption key, encryption ensures that sensitive data remains secure, even if the device is lost or stolen. This is especially relevant in a world where cyber-attacks are becoming increasingly common and sophisticated.
Maintaining data integrity
Encrypting data ensures that the information is not altered during storage or transmission. This is crucial to prevent malicious manipulation and to ensure that data remains accurate and reliable. In the context of data transmission, encryption protects information against unauthorised interception and modification. This is especially relevant in 2026, as ransomware has evolved beyond simply locking data: according to Picus Labs' Red Report 2026, the "data encryption for impact" technique decreased by 38% in one year, from 21% of samples in 2025 to 12.9% in 2026. Attackers now combine encryption with prior data theft to threaten the release of the stolen data (double and triple extortion). This makes defensive encryption a necessary but insufficient layer; if data is exfiltrated before being encrypted, the organization remains vulnerable.
Furthermore, encryption helps detect any alteration to the data, since any change to the encrypted information will result in unreadable data when decrypted without the correct key.
Data migration to cloud storage
Data encryption is essential for secure data migration to cloud storage. Encrypting information before transferring it to the cloud ensures that data remains protected from unauthorized access during migration. This is especially important because data can be vulnerable to interception and cyberattacks while moving over public or private networks.
By 2026, the shared responsibility model for cloud providers will be a well-established standard: the provider protects the infrastructure, but data encryption and key management remain the responsibility of the organization.
Options like BYOK (Bring Your Own Key) allow for maintaining cryptographic control even when data resides with third parties. In fact, according to Encryption Consulting's Global Encryption Trends 2026 report, 62% of the market is migrating to cloud-based HSM modules to balance rapid scalability with data residency laws and sovereignty requirements. This is also essential for GDPR compliance, which mandates appropriate security measures for the processing of personal data.
Data Encryption and GDPR: Obligations and New Developments in 2026
The relationship between data encryption and the GDPR is direct and close. The General Data Protection Regulation (EU Regulation 2016/679) sets out in Article 32 that data controllers must implement appropriate technical and organizational measures, including the encryption of personal data as a recommended security measure.
In practice, the GDPR and data encryption interact in several key scenarios:
- Reducing the risk of penalties: If a security breach occurs but the data was properly encrypted, supervisory authorities often consider the risk to data subjects to be low, reducing the notification obligation and applicable penalties.
- International transfers: Encryption is a complementary measure in data transfers to third countries without an adequacy decision, in accordance with standard contractual clauses.
- Privacy by design: The principle of "privacy by design" requires that encryption be incorporated at the design stage of systems and applications, rather than as a later addition.
In 2026, the regulatory scope has expanded on two fronts. First, the NIS2 Directive, in force since October 2024, requires operators of essential and critical services across the EU to implement encryption measures as part of their risk management, with penalties of up to €10 million or 2% of their total annual global turnover for non-compliance.
Second, Google will roll out mandatory HTTPS in Chrome during 2026 in two phases: in April for more than 1 billion users with Enhanced Protection enabled, and in October for the entire browser. TLS encryption on the web will thus cease to be optional and become the de facto universal standard.
Data encryption within a comprehensive cybersecurity strategy
Data encryption cannot be considered in isolation. To be truly effective, it must be integrated into a comprehensive cybersecurity strategy that includes continuous threat exposure management (CTEM), early vulnerability detection, and incident response.
Phishing prevention, Zero Trust policies, and data encryption together form a defense-in-depth model that significantly increases an organization's resilience against today's threats.
By 2026, this approach is no longer just a recommendation: the Global Encryption Trends 2026 report indicates that encryption has risen to the level of strategic discussion at the board level, driven by AI convergence, the shortening lifespan of certificates, and quantum risks. Organizations that have adopted centralized and automated crypto governance achieve annual savings exceeding $3 million and reduce breach response times by 45%.
Monitoring that encryption is properly implemented and that there are no gaps in its application requires continuous visibility.

Ransomware 3.0: How malware evolves and what measures to take
Just a decade ago, the term "data breach" sounded like something out of a science fiction movie. Today, it's the biggest nightmare for any IT director and, increasingly, for any citizen who stores their life on a hard drive. But the danger has evolved.
We are no longer dealing with a simple virus that locks your screen; we have fully entered the era of ransomware 3.0.
In this article, we'll break down what this evolutionary leap means, why traditional defenses are becoming inadequate, and how, in Enthec, we can change this to help mitigate these risks before the damage becomes irreversible.
The evolutionary leap: from file blocking to total extortion
To understand where we are, we must first look back. The ransomware 1.0 was opportunistic: a mass email would go out, someone would click a link, and their files would be encrypted. Version 2.0 introduced "double extortion," in which attackers, in addition to encrypting data, stole it and threatened to publish it.
Ransomware 3.0 goes one step further.. It's no longer just malicious software; it's a highly professionalized and customized business model.
What characterizes this third generation?
This new phase focuses on triple extortion.. Cybercriminals not only target the main organization but also contact its customers, suppliers, and employees directly. If the company doesn't pay, they pressure its business partners by informing them that their private data is at risk.
Furthermore, ransomware 3.0 relies on the Ransomware-as-a-Service (RaaS) model. Malware developers rent their code to "affiliates" in exchange for a commission. In this way, even criminals with limited technical skills can launch devastating attacks using highly sophisticated infrastructure.
Why businesses remain vulnerable
Despite investment in antivirus and firewalls, security vulnerabilities continue to grow. Why is this happening?
The answer lies in the exposure.. Today's businesses operate in hybrid environments, with remote employees, cloud services, and a vast amount of digital assets they often don't even know they have. Attackers don't usually "break down" the door; they simply find a key someone left in the lock.
The importance of looking beyond the perimeter
The traditional approach to cybersecurity focused on protecting resources within the corporate network. But in the era of ransomware 3.0, the threat often originates from outside: in online dark web forums where stolen credentials are sold, or on misconfigured servers exposed to the internet without anyone noticing.
Aquí es donde aparece la Gestión Continua de la Exposición a Amenazas. . It's not enough to conduct an audit once a year; you have to monitor your exposure surface every minute of every day.
The human factor: why are you also in the spotlight?
We often think that these attacks only affect large multinational corporations. However, ransomware 3.0 has democratized the risk. Attackers have discovered that individuals are much easier to exploit and, when combined, offer enormous profitability.
Think about it for a moment: How many times have you used the same password for your personal email and for a shopping app? How much personal information is scattered across the internet due to security breaches in services you used years ago?
Most successful attacks do not begin with a complex hack, but with a human oversight or a prior information leak.
Qondar: protecting your digital identity
This is where prevention becomes personal. Qondar is the ally for the individual, the independent professional, or the manager who wants to protect their private sphere.
Qondar applies military-grade cyber surveillance capabilities tailored to individual needs. It alerts you if your email address appears in a leaked database, if your passwords are exposed, or if someone is using your identity for illicit purposes.
At this stage of the user journey, when you're already aware that the danger is real, having a tool that continuously monitors your exposure is essential digital hygiene. By protecting yourself with Qondar, you not only protect your files but also cut off the supply chain that feeds ransomware 3.0 cybercriminals.
Practical measures to mitigate the risk of ransomware 3.0
Beyond having monitoring tools, there are habits and strategies that should be part of the DNA of any conscientious organization or user.
1. Implement the Zero Trust model
The premise of the model Zero Trust is simple: trust nothing and no one, whether inside or outside your network. Every access attempt should be verified. This drastically limits malware's ability to spread once it manages to infiltrate a device.
2. Immutable backups
With traditional ransomware, restoring a backup was sufficient. With ransomware 3.0, attackers attempt to locate and delete your backups before encrypting your data. Immutable backups (those that cannot be modified or deleted for a specified period) are the only real guarantee of recovery.
3. Education and awareness
Phishing Phishing remains the number one entry point. Training teams to identify red flags, such as emails with unwarranted urgency or suspicious senders, is just as important as having the best software.
4. Constant external monitoring
As we mentioned with the CTEM approach, the risk changes every hour.. New vulnerabilities appear daily (the famous Zero-Days).). Using solutions that constantly scan your display surface, such as those we offer in Enthec, can mean preventing a disaster before it happens.
The future of cybersecurity is preventative.
The digital threat landscape is hostile, but not invincible. The evolution towards ransomware 3.0 forces us to stop being reactive.. We can't wait for a ransom note to appear on the screen before we start thinking about security.
Modern cybersecurity is all about visibility. Knowing what an attacker knows about us gives us a crucial competitive advantage. Whether you're a business concerned about continuity or an individual who values privacy, the key is proactive monitoring.
Continuous Threat Exposure Management tools are not just for experts; they are for anyone who wants to sleep soundly in an interconnected world.
Do you want to know what the internet knows about you?
Information is power, but only if you get to it before the criminals do. Don't wait to become just another statistic in next year's cybersecurity reports.

SIM Swapping: what it is, how it works and how to avoid this scam in 2026
Our mobile phone is more than just a device: it's the center of our digital lives. We use it to access our social media, online banking, medical services, and work communications.
But have you ever thought about what would happen if someone hijacked your phone number? This is precisely what happens with SIM swapping, an impersonation technique that is on the rise.
Before going into details, it's worth presenting a solution that can be very useful for detecting an attack in time. Qondar, our tool, is a platform for individual cyber-surveillance to anticipate digital threats.
Qondar is an early warning system that identifies potential exposure of your personal information online and can help you detect signs of SIM swapping before it's too late.
What is SIM swapping?
You may have read about it in recent news or heard it called SIM swap or SIM swapping, but what exactly is SIM swapping?It is a digital scam that involves duplicating your SIM card without your consent.
In other words, a cybercriminal can take over your phone line, redirecting your calls, messages, and, most worryingly, the verification codes that many services send via SMS.
The objective is clear: access your accounts using popular two-step verification (2FA) systems. Many banks, social media platforms, and email services use this method to verify your identity, but if the attacker already has your phone number, they can receive these codes and access your data as if they were you.
SIM swap: how does it work?
The technique is not new, but it has gained popularity in recent years. The modus operandi usually follows this scheme:
- Obtaining personal data. Through leaks, social engineering, or even social networks, the criminal collects enough information about you (name, ID, address, phone number, etc.).
- Impersonation. With this information, they contact your phone provider, posing as you, and request a duplicate SIM card, claiming the device has been lost or damaged.
- Activating the new SIM. Once the operator validates the request, the new SIM is activated, and your line will no longer be available on your device.
- Account access: The attacker tries to access your accounts. If you have SMS authentication enabled, he is already on the hook.
In minutes, someone can gain complete control over your personal data, networks, online banking, and more.
How can you tell if someone has swapped your SIM card?
Detecting an attack in time can mean avoiding serious losses or blocking access before it causes damage. Here are the clearest warning signs:
- Your mobile phone suddenly loses coverage in an area where you normally have a signal. You're not receiving calls or messages, but there's no apparent technical cause.
- You receive notifications of changes to your account (changed passwords, login attempts) in services you haven't touched.
- There are unrecognized bank transactions or transfer attempts on your account.
- You receive an SMS or call from your operator confirming a SIM change that you did not request.
- You cannot access your email, social media, or online banking with your usual credentials.
If you experience any of these signs, act immediately. Call your operator to block the duplicate, contact your bank, and change the passwords for your main accounts from a secure device.
A tool like Qondar, our individual cyber-surveillance solution, can alert you to signs prior to an attack, such as the appearance of your data in security breaches or on dark web forums, allowing you to react before the SIM swap materializes.
How to protect yourself from SIM swapping?
It is normal to wonder how to avoid SIM swapping or what we can do to protect ourselves from this dangerous technique. Here are some recommended measures:
1. Minimize the information exposed on networks
Avoid sharing information such as your phone number, date of birth, or address on social media. Even seemingly harmless information can be used to create a fake profile and impersonate you.
2. Change authentication methods
Whenever possible, avoid SMS authentication. Opt for authentication apps like Google Authenticator, Authy, or physical keys (like YubiKey), independent of your mobile phone line.
3. Activate notifications on your operator
Some carriers allow you to notify them of any line changes, such as SIM card duplication or portability requests. Activate these notifications if available.
4. Use unique passwords and a password manager.
If an attacker can't guess or recover your password, it will be much harder for them to access your accounts, even with just your phone number. Use long, unique passwords for each service, and manage them with a secure password manager.
5. Continuously monitor your digital exposure with Qondar
Qondar, Enthec's solution for individual users, continuously monitors whether your personal data has appeared in security breaches, on the dark web, in cybercriminal forums, or in any space where it could be used to prepare a SIM-swapping attack.
Thanks to its CTEM (Continuous Threat Exposure Management)- based model, Qondar does not perform a one-off analysis of your situation; it continuously evaluates your digital risk and sends you personalized alerts when it detects signs of danger.
SIM swapping: How to prevent it with an early warning tool
Attacks don't always come in visible form. Often, personal data leaks online before a SIM swap. Emails, passwords, phone numbers, or addresses leaked in stolen databases are the cybercriminal's first step.
Qondar lets you know if your data has appeared in a security breach, if someone is trying to steal your identity, or if your phone number has been compromised. This information is vital so you can take timely measures, such as changing your password, contacting your carrier, or even temporarily blocking certain services.
Thanks to its model-based approach, CTEM (Continuous Threat Exposure Management), Qondar doesn't just analyze a snapshot of your digital situation; it continuously assesses your risks and adapts to the changing cybersecurity environment.
Why is SIM swapping an increasing threat in 2026?
SIM swapping is not an isolated problem. According to data from Europol and the National Cryptologic Center, these types of scams are rising in Europe. Attackers are targeting prominent public figures as well as ordinary citizens whose data has been exposed online.
SIM swapping is neither an isolated nor a new problem, but its reach has continued to grow. Several factors explain this increase:
- Greater digitization of critical services: Banking, insurance, healthcare, and public administration use the telephone as a verification tool, increasing the value of the phone number for attackers.
- Proliferation of data leaks. Every security breach that exposes millions of records provides criminals with the material they need to prepare social engineering attacks.
- Increasingly sophisticated techniques. Attackers use AI to generate convincing conversations with operators, mimic voices, or create fake documentation.
- Low barriers to entry. There are kits and tutorials on the dark web that make it easier for actors with little technical experience to carry out this attack.
The consequences of being a victim of a SIM swapping scam can include unauthorized bank transfers, identity theft to commit crimes, blocking of personal and professional accounts, loss of access to medical services or insurance in your name, and irreversible loss of digital assets such as cryptocurrencies.
Therefore, having tools that perform this monitoring automatically and constantly has become a real necessity.
What to do if you have already been a victim of SIM swapping?
If you believe you have suffered a SIM swap attack, act quickly by following these steps:
- Call your operator immediately. Report what happened and request that they block the fraudulent duplicate and restore control of your line.
- Contact your bank. Report the situation so they can block potential transfers and review your recent account activity.
- Change passwords from a secure device. Prioritize email, online banking, and social media. Use a trusted Wi-Fi network, never a public one.
- File a complaint. Contact the State security forces (National Police or Civil Guard) and INCIBE (017, the cybersecurity helpline).
- Review and strengthen your digital security. Remove SMS 2FA from all possible services and activate more secure authentication methods.
What can you do today?
Now that you know what SIM swap is and how easy it is to fall victim to this scam, you can make more informed decisions to protect yourself.
We recommend:
- Review your authentication methods in the most important digital services.
- Avoid using the phone number as the only verification method.
- Try Qondar, our cyber surveillance platform for individuals, which helps you keep your data safe with personalized alerts.
SIM swapping is a real, silent, and dangerous threat. You don't have to be a celebrity to be targeted: all it takes is for your data to have been leaked, even if it's on a website you registered with years ago.
Protecting yourself requires a combination of prevention, good digital practices, and tools that work for you.
Qondar by Enthec is precisely that: a digital shield that alerts you when something is wrong, when your data appears where it shouldn't. Thanks to its continuous monitoring capacity and threat exposure management, it becomes a key ally in preventing SIM swapping before it happens.

The Relevance of Artificial Intelligence in Cybersecurity
Artificial intelligence (AI) has become a key player for many people in different personal and professional areas, but we must also know its ability to protect us against digital threats.
From businesses to individuals, we are all exposed to constantly evolving cyberattacks, where the combination of cybersecurity and artificial intelligence plays a decisive role. AI applied to cybersecurity improves the ability to detect and prevent threats, allowing a more efficient and faster response to possible attacks.
In this article, we will discover why artificial intelligence and cybersecurity are so closely linked, the applications of this technology, and its positive impact on our daily lives.
What is artificial intelligence in cybersecurity and why is it essential in 2026?
Artificial intelligence in cybersecurity is the set of technologies, algorithms, and machine learning systems specifically designed to identify, prevent, and neutralize digital threats autonomously and in real time. Unlike traditional tools, AI is not limited to recognizing known patterns, but continuously learns from new attack vectors.
The current cyber threat landscape has changed drastically:
- The deepfake attacks. Identity theft has increased by 850% since 2024, with generative AI creating fake audio and video recordings of executives authorizing fraudulent transfers.
- Adaptive ransomware uses machine learning to identify each organization's most valuable data before encrypting it, maximizing the pressure to pay ransoms.
- Polymorphic attacks change their code in real time, evading traditional detection systems that rely on static signatures.
According to the Global Cybersecurity Report 2026, 87% of security leaders identified AI-related vulnerabilities as the fastest-growing cybersecurity risk by 2025, surpassing even ransomware and supply chain attacks.
Why is artificial intelligence critical in cybersecurity?
The digital threat landscape has reached unprecedented complexity. Cybercriminals now employ the same AI technologies that organizations use to defend themselves, creating a digital battleground where only the most advanced systems survive.
Artificial intelligence for cybersecurity stands out because it can:
- Analyze large volumes of datain record time. AI for cybersecurity processes massive volumes of information that no human team could analyze, such as analyzing millions of security events per second, reducing the average detection time, and correlating information from multiple sources.
- Detecting suspicious patterns that might go unnoticed by humans through the analysis of anomalous behavior.
- Learn and adapt constantlyto improve its effectiveness. The human factor remains the weakest link in cybersecurity. According to IBM Security, 95% of security breaches in 2025 involved some type of human error.
The key lies in its ability to act proactively and automatically, making defense barriers more dynamic in the face of constantly changing threats.
Applications of AI for cybersecurity
Artificial intelligence applied to cybersecurity has a range of applications, ranging from threat detection to response automation. Here are some of the highlights:
Real-time threat detection
Advanced algorithms enable AI to analyze data traffic and detect anomalous behavior in real time. For example, it can identify an attempted intrusion into a network before it causes damage. This significantly reduces reaction times and mitigates potential risks.
Attack prevention
AI can anticipate attackers' movements by studying previous patterns. From here, it is possible to create more robust systems designed to prevent attacks before they occur. For example, some AI models can identify phishing emails even if they use advanced spoofing techniques.
Phishing attacks have evolved dramatically. Modern systems no longer rely solely on blacklists of malicious domains; instead, they employ natural language processing (NLP) and multimedia content analysis.
Response Automation
When an attack is detected, AI can automatically make decisions, such as blocking unauthorized access or neutralizing malware. By acting immediately, AI saves time and minimizes potential damage.
Information protection
AI is also crucial for protecting sensitive business and user data. You can detect data extraction attempts or unauthorized access by analyzing access patterns and blocking them in real-time.
Predictive and shared threat intelligence
Modern cybersecurity and artificial intelligence platforms integrate threat information from multiple global sources:
- Dark web analysis to identify discussions about vulnerabilities or leaked data from your organization.
- Correlation of attack campaigns across industries to anticipate which sectors will be targeted next.
- Early identification of compromised corporate credentials in third-party breaches before they are used in credential attacks.
Benefits of artificial intelligence in cybersecurity
Combining cybersecurity and artificial intelligence offers numerous benefits that enhance protection and optimize resource use. Here are some of the most important ones:
Early Threat Detection
One of the biggest challenges in cybersecurity is identifying threats before they cause damage. AI can analyze large amounts of data in seconds, making it possible to detect anomalies that might go undetected with traditional methods.
Prevention of human error
Human error is one of the leading causes of cyberattacks. Weak passwords, clicks on suspicious links, and incorrect configurations are gateways for attackers. AI helps minimize these risks by automating tasks and alerting users to unsafe behaviors.
Although we mustn't forget the risks of AI.
Adaptability
As attackers develop new techniques, AI systems can adapt quickly, learning from each attack attempt to strengthen defenses. This ensures that protective measures are always one step ahead.
The future of artificial intelligence applied to cybersecurity
The role of artificial intelligence in cybersecurity will only grow in the coming years. With the rise of the Internet of Things (IoT), the number of connected devices will increase, expanding the attack surface. AI will be instrumental in managing this complexity and developing more innovative, personalized solutions.
In addition, collaboration between humans and machines will be essential. Although AI is powerful, it does not replace human judgment. Instead, it amplifies our capabilities, allowing cybersecurity experts to focus on more strategic tasks.

IAM in cybersecurity: the fundamental pillar for protecting access in your organization
Access to systems, applications, and data continue to grow each year, making it a strategic priority to control who can enter, when, and with what permissions. The concept of IAM in cybersecurity is not just about passwords or logins, but a complete discipline that manages digital identities and permissions to reduce risks and maintain control.
Many companies invest in firewalls, antivirus software, and network monitoring, but they often forget that the main entry point is often through legitimate user access. A credential leak can open more doors than any technical exploit.
Therefore, understanding what IAM is in cybersecurity and how to apply it effectively is key for any organization that wants to protect its digital assets.
What is IAM in cybersecurity, and why does it matter?
When we talk about IAM in cybersecurity, we are referring to Identity and Access Management systems, that is, tools and processes that manage digital identities and control access to technological resources.
In simple terms, IAM defines who can access what and under what conditions. . But behind that definition lies a whole ecosystem of policies, authentication, roles, and audits.
Essential elements of an IAM system
A well-implemented IAM system typically includes:
- Authentication: identity verification (password, biometrics, MFA).
- Authorization: assignment of permissions according to roles.
- Identity management: user registrations, cancellations, and changes.
- Audit and traceability: access and action log.
These components work together to reduce human error, limit unnecessary privileges, and detect suspicious behavior.
The real problem: uncontrolled access and digital exposure
Many organizations believe they are in control because they use strong passwords or multi-factor authentication. . However, the risk usually lies elsewhere: exposure of assets on the internet.
Forgotten servers, old active accounts, misconfigured repositories… All of these form part of the attack surface. And without continuous monitoring, IAM alone is not enough.
This is where a more advanced approach comes into play: the Continuous Threat Exposure Management (CTEM).. This model not only manages identities but also continuously monitors which externally visible elements attackers can exploit.
IAM and CTEM: a necessary combination
Integrating cybersecurity IAM with CTEM strategies allows to move from a reactive to a preventative approach. It's not enough to protect access points; we need to know what could be attacked before anyone even tries.
Why combine both approaches
- IAM controls who enters.
- CTEM analyzes which doors are visible.
- Together, they allow for prioritizing real risks.
An IAM system without external visibility is like having new locks on a house with open windows. That's why more and more companies are seeking solutions that combine identity management with continuous monitoring of digital exposure.
How does IAM affect business security?
The impact of cybersecurity IAM extends beyond the IT department. It directly influences business continuity, reputation, and regulatory compliance.
Tangible benefits for the organization
A robust identity management model involves reducing unnecessary access,thereby reducing the likelihood of intrusion. It also strengthens the organization's internal controls, improves the user experience through centralized access, and simplifies regulatory compliance.
In addition, it is possible to detect anomalous patterns, such as a user logging in from two different countries within a few minutes.
The role of cyber surveillance in protecting access
The evolution of threats has changed the rules. Today, attacks don't always seek to directly compromise systems; they often first scan for existing assets and identify potential weak points.
That's where Enthec's proposal comes in,focused on cyber-surveillance solutions geared towards CTEM. Their solutions continuously analyze the exposed digital surface and detect risks before they escalate into incidents.
Kartos: business approach
Within this approach, Kartos stands out, designed for companies that need continuous visibility of their digital exposure.. The solution identifies exposed assets, credential leaks, and potential identity-related attack vectors.
This aligns directly with the cybersecurity IAM strategy: if you know which credentials or access points are compromised, you can take action before they are used.
Signs that your organization needs to improve its IAM
Many companies don't detect flaws in their identity management until an incident occurs. Some warning signs include:
- Users with permissions they don't need.
- Active accounts of employees who no longer work.
- Access without an audit log.
- Credential sharing.
- Lack of periodic review of privileges.
If any of these points appear in a cybersecurity audit, the IAM system will likely need adjustments.
Best practices to strengthen your IAM strategy
Effectively implementing cybersecurity IAM depends not only on the tool used, but also on how it is configured and managed.
. These practices help improve results:
Least privilege policies
Each user should only have the access necessary for their work. Nothing more. This reduces the impact if an account is compromised.
Periodic review of access
Permits should be reviewed regularly, especially after changes in position or employee departures.
Multi-Factor Authentication
It's not a magic solution, but it adds an extra layer of protection against credential theft.
Continuous monitoring
This is where cyber surveillance becomes valuable. Knowing what's happening outside your network can be just as important as monitoring what's happening inside.
IAM as part of a mature security strategy
A mature cybersecurity organization does not simply install tools; it builds a coherent ecosystem.. IAM must be integrated with monitoring, risk analysis, and external visibility.
The current trend points toward unified models in which digital identity becomes the central focus of protection. This is no coincidence: identity is the new perimeter.
Therefore, when someone asks what IAM is in cybersecurity, the most accurate answer would be: the system that decides who can act within your digital infrastructure and under what conditions.
Companies that anticipate these trends will have an advantage against increasingly sophisticated threats.
Cybersecurity IAM has become an essential foundation for any digital protection strategy.. No matter the size of the company, if there are systems, data, or users, there is risk.
The difference lies in anticipation. Combining identity management with continuous exposure monitoring enables you to detect weaknesses before they are exploited.
If you want to know your actual level of exposure and how to strengthen your access control, now is the time to review it with Enthec. Analyzing your digital surface today can prevent an incident tomorrow.
Information Security: 5 Best Practices to Implement in Your Company
In 2026, Data protection has become a critical priority in the business environment. Good information security practices are essential for companies to protect their digital assets against cyber threats that are evolving at an unprecedented rate, driven by AI and increasingly sophisticated techniques.
In this article, you will discover what good practices in information security are, why they are essential in your organization, and how to implement 5 essential measures that will strengthen your data protection strategy.
What is information security?
Information security protects information and information systems against unauthorized access, use, disclosure, interruption, modification, or destruction. It has become a critical obligation for organizations.
Companies of all sizes and sectors handle a wealth of information, from personal and sensitive employee and customer data to financial and intellectual property information. This information is a valuable asset that, if compromised, can cause serious harm to data subjects and significant damage to an organization's reputation and financial viability.
Therefore, organizations must establish procedures to ensure information security, protect against threats that may affect it, and ensure the continuity of their operations.
Procedures to Ensure Information Security
These procedures should include information security policies, access controls, information security training, security incident management, and disaster recovery and business continuity plans.
- Information security policies provide a framework for managing information security in an organization. These policies define employee responsibilities, security requirements for information systems, and procedures for handling security incidents.
- Access controls are measures that limit information access to authorized persons. These can include passwords, key cards, and two-factor authentication.
- Information security training is essential to ensure that all employees understand information security and their responsibilities regarding it. This training should cover topics such as the secure handling of information, identifying security threats, and responding to security incidents.
- Security incident management involves identifying, tracking, and resolving security incidents. These incidents typically include phishing attacks, data breaches, and different types of malware.
Disaster recovery and business continuity plans detail how an organization will respond to a security incident that results in a significant loss of information or operational capacity and nullify or minimize its effects.
Key Terms in Information Security
Three key terms allow us to understand the concept and constitute the characteristics of information security: confidentiality, integrity, and availability.
Confidentiality
It refers to the protection of information from disclosure to unauthorized parties. Confidentiality measures include data encryption, access control, and user authentication.
Integrity
In this case, it refers to protecting information against unauthorized modification or deletion. This ensures that the information is accurate and complete. Integrity measures include version control, backups, and intrusion detection systems.
Availability
It refers to ensuring that information and information systems are available for use when needed. Availability measures include system redundancy, disaster recovery, and business continuity planning.
These 3 characteristics of information security should guide organizations in the development of security policies, procedures and controls.
However, information security is not a one-size-fits-all solution that can be applied uniformly across organizations. Each organization must assess its own risks and develop an information security strategy that is tailored to its specific needs.
In addition, information security is not a static state, but an ongoing process. As threats and risks evolve, so do security measures. This requires constant vigilance, regular evaluation of safety policies and procedures, and ongoing user education and training.
5 Best Practices in Information Security
Among the best practices in information security, implementing these five in your company that we detail below is the starting point for any corporate information security procedure.
1. Security Updates
Security updates are critical to
protecting organizations' information systems.
These updates contain patches that address the latest software vulnerabilities. Keeping systems up-to-date minimizes the risk of cyberattacks.
Discover the foremost common types of cyberattacks through our blog.
2. Access to information control
Access control is another crucial practice. It involves ensuring that only authorized individuals have access to sensitive information.
The organization should implement role-based access control policies to limit access to information based on its category and the job responsibilities of its employees.
3. Backups
Regular backups are essential for data recovery in the event of information loss.
The organization should make backups on a regular basis and store them in a safe place. In the event of a cyberattack, backups allow information to be restored and operational activity to be maintained.
4. Password management
Effective password management is vital for information cybersecurity.
It's critical to encourage employees to use strong, unique passwords for each account, as well as to renew them regularly. Additionally, it is advisable to implement two-factor authentication to add an extra layer of security.

5. Staff Awareness
The human factor remains the weakest link in the security chain. In 2026, social engineering powered by generative AI and highly personalized phishing are highly effective attack techniques that exploit a lack of awareness, creating emails and messages virtually indistinguishable from legitimate communications.
Your employees need to be informed about cybersecurity best practices and how to identify potential threats. Regular training is critical for them to stay up-to-date on the latest threats and how to prevent them.
