Applying OSINT to cybersecurity: A valuable guide for professionals and teams
Protecting the information is no longer just a task for large corporations or government departments. Every company, regardless of size, is exposed to risks that evolve at a dizzying pace.
In this context, open source intelligence (OSINT) has become a key tool in cybersecurity. But what exactly does applying OSINT mean in the professional field, and how can it make a difference in an increasingly hostile digital environment?
Before delving into the details, it's worth highlighting the role of Kartos, Enthec's solution designed specifically for companies seeking to elevate their cybersecurity strategy to the next level. Kartos allows you to continuously monitor your exposure to external threats, automating processes for collecting and analyzing public information about the company, its employees, and its digital infrastructure.
What is OSINT?
The term OSINT (Open Source Intelligence)refers to a process by which publicly available information is collected, analyzed, and utilized, information that is legally accessible to anyone, to obtain practical knowledge.
In cybersecurity, this means detecting potential attack vectors before they are exploited, finding leaked information from an organization, or anticipating vulnerabilities using data available on the network.
Why is OSINT important in cybersecurity?
Applying OSINT techniques enables security teams to anticipate threats, gain a deeper understanding of their public exposure, and identify and address weaknesses before malicious actors can exploit them. It's like conducting an audit from the attacker's point of view.
Among the most relevant benefits, the following stand out:
- Early identification of information leaks.
- Detection of fake domains or profiles that impersonate the brand.
- Assessment of the level of exposure of key employees.
- Discovery of leaked credentials on forums and dark websites.
All of this can be accomplished without compromising the legality of the process, as all the information is extracted from open-source OSINT sources, including search engines, social networks, public databases, forums, among others.
The OSINT process step by step
Although there are many methodologies, the OSINT process is typically divided into five fundamental phases. Understanding them is key to effectively integrating this discipline into cybersecurity workflows.
1. Definition of objectives
Before you start searching for data, it's essential to know what you're looking for. This could include research on a specific company's exposure, a manager's fingerprint, or the evaluation of an external supplier.
2. Selection of OSINT sources
This is where open-source OSINT comes in: from Google and social media, to logs, DNS records, pastebin services, forums on the deep web, or platforms like Shodan or Have I Been Pwned.
3. Data collection
At this stage, we utilize automated or semi-automated OSINT tools to facilitate the gathering of large amounts of information. . This is essential to document this phase well, so that the data is traceable and verifiable.
4. Analysis and correlation
Data alone is worthless if it's not interpreted correctly. Here, the collected information is analyzed, irrelevant information is discarded, and hypotheses about potential risks or vulnerabilities are generated.
5. Presentation and performance
Once the level of exposure is understood, action is necessary: delete sensitive information, change leaked passwords, and contact platforms to remove unauthorized content, among other measures.
Apply OSINT with a strategic vision
OSINT is often associated with specific investigative tasks, such as "ethical hacking." However, the true power of OSINT lies in its integration into a continuous defense strategy, known as CTEM (Continuous Threat Exposure Management).
In this sense, Kartos allows you to make that leap in quality by offering:
- Daily automation of the OSINT cycle.
- Customized reports for each company.
- Proactive detection of leaks, malicious domains, data leaks, and impersonation.
- Integration with existing cybersecurity team workflows.
With a tool like Kartos, companies can stop being defensive and start playing offense digitally, understanding what sensitive information is being leaked or published without authorization.
Good practices for applying OSINT in teams
In addition to having adequate tools, it is essential to develop operational routines and internal policies that allow you to get the most out of OSINT:
- Train employees about what information they can share on networks.
- Establish periodic controls on the organization's digital footprint.
- Define clear responsibilities within the security team to manage these tasks.
- Combine OSINT with other disciplines, such as threat intelligence, red teaming, or risk management.
The use of OSINT in cybersecurity is not a fad or a mere technical curiosity. It is a real necessity in a context where every leaked or mismanaged piece of data can be a security breach.. Therefore, adopting a proactive approach, with tools like Enthec's Kartos, can mean a considerable advantage for companies that prioritize their digital security.
Cybersecurity is not just about reacting to incidents; it's about anticipating them. And to anticipate, nothing better than seeing what the attackers see.

Is your sensitive data circulating on the internet without your knowledge? Here's how to check.
Shopping online, booking a trip, managing your bank account from your mobile phone, or simply signing up for a social network means leaving a trail. The worrying thing is that, often, we are not aware of the extent to which our sensitive data is exposed, or worse still, is already circulating on the network without our knowledge.
In this article, we will discuss how to verify if your sensitive data has been compromised, what types of information are considered critical under the GDPR, and how to protect it with specialized tools, such as Qondar.
First of all, what exactly is sensitive data?
Not all personal data is equally relevant or requires the same level of protection. According to the General Data Protection Regulation (GDPR), sensitive personal data is that which reveals:
- The ethnic or racial origin
- The political opinions
- The religious or philosophical convictions
- The Union membership
- Data genetic or biometric
- Data related to the health
- The sexual life or sexual orientation of a person
In addition to these, sensitive data is also considered to be that which, by its nature, may pose a greater risk if it falls into the wrong hands, such as identity documents, bank accounts, passwords, physical addresses, personal phone numbers, or information about your children.
Knowing what a person's sensitive data is is crucial to understanding why it is so attractive to cybercriminals.

Why is it so easy for your data to end up in the wrong hands?
In many cases, you're not doing anything wrong. One of the platforms you're registered with simply suffers a breach, or you inadvertently access an unsecured public Wi-Fi network. Even a simple download can open the door for your information to end up in a black market database.
The worrying thing is not just the leak itself, but the time that passes until the user finds. that data may have been circulating on obscure forums for months (or even years) without even knowing.
How do you know if your sensitive personal data is already online?
Digital exposure is more common than it seems
You don't have to be a public figure or a company executive to be a victim. Indiscriminate attacks are the most frequent, and many cybercriminals operate under the logic of “the more, the merrier.”
There are free platforms to check if your email or passwords have been leaked, such as Have I Been Pwned. However, these tools provide limited vision and shallow insight into the problem.
Qondar, your ally for continuous protection
This is where Qondar comes in, a solution developed by Enthec, specializing in cybersecurity and cyber surveillance. Qondar goes a step further than conventional platforms: it doesn't just alert you if your email has been leaked, but also performs a continuous surveillance on the open web, the deep web, and the dark web to detect whether your sensitive data is being traded, shared, or used without your consent.
Qondar is part of a new generation of Continuous Threat Exposure Management (CTEM) tools, a proactive approach that enables you to anticipate potential cyberattacks rather than just react after they occur.
Thanks to its automated intelligence engine, Qondar monitors your fingerprint and alerts you in real-time if any information is compromised, including passwords, card numbers, identification documents, or sensitive personal data.
What can I do if I discover my data has been leaked?
We recommend:
- Cambia tus contraseñas inmediatamente. Start managing passwords for your most sensitive accounts, including email, banking, and social media.
- Activate two-step verification whenever possible.
- Keep a close eye on your bank accounts and digital platforms with increased attention during the following months.
- Contact the affected services to know the extent of the leak.
- Consider using a tool like Qondar to receive early warnings and make timely decisions.
The importance of prevention: reacting is not enough
The reality is apparent: Protecting your sensitive data is not optional; it is necessary. . Doing it just once isn't very useful. Digital exposure is dynamic and constantly changing. Therefore, the approach must be continuous, as proposed by Continuous Threat Exposure Management.
With Qondar, you have a solution that is efficient, automatic, and in real-time, designed for individuals who value their privacy and security in today's digital world.
What sets Qondar apart from other solutions?
- Complete coverage: Tracking multiple layers of the internet, not just the surface.
- Proactive detection: Qondar doesn’t wait for a crisis to act.
- Simple interface: No advanced technical knowledge required.
- Clear and helpful alerts: You will know exactly what information is compromised.
Furthermore, being developed by Enthec, a company with extensive experience in the business field thanks to Kartos (the corporate solution), Qondar benefits from a solid and proven know-how record in the world of cybersecurity.
What if nothing has ever happened to me?
That is precisely the trap. Many leaks do not generate immediate effects. and can take months for someone to use that data against you. A hacked account could be silently used to spy on, send spam to, or even impersonate you on other platforms.
According to a 2022 Norton study,1 in 5 people in Spain have been victims of some cyber fraud,but only half were aware of it at the time it occurred. The other half discovered it late, after the damage had already been done.
Protect yourself now. Because tomorrow could be too late.
If you've made it this far, it's because you know something isn't quite right about how we protect (or don't protect) our information on the Internet. Good intentions are not enough.. Your information circulates, with or without your permission. The question is: do you want to know before it happens or after it happens?
Qondar can help you regain control. Start your digital surveillance today and keep your sensitive data out of the hands of cybercriminals.
Are you unsure whether your sensitive personal data has already been exposed? Find out today with Qondar. Because in the digital world, the best defense is anticipation.

Ransomhub and the new reputational threat
We live in a time when cyberattacks no longer only seek to steal information or collapse systems, but also directly damage the reputation of organizations.
One of the most recent and worrying examples is Ransomhub. This group is reinventing the way ransomware groups operate, with a strategy that combines blackmail, public extortion, and fear marketing.
Before delving into detail, it's worth briefly discussing Kartos, Enthec's solution for businesses seeking to stay ahead of emerging threats. Kartos isn't an antivirus or a simple perimeter shield. It's a Continuous Threat Exposure Management (CTEM) platform designed to help organizations detect vulnerabilities, track external threats, and make informed decisions before damage is real.
In the current context, with threats like Ransomhub, solutions like Kartos are no longer just an “extra” but an essential asset.
What is Ransomhub?
Ransomhub is a cybercriminal group specializing in ransomware attacks, a type of malware that blocks access to systems or encrypts a company's data until a ransom is paid. What sets Ransomhub apart from other similar groups isn't so much its technology, but its strategic approach: its accurate weapon is the victim's reputation.
Unlike other cybercriminals, who encrypt data and wait for payment, Ransomhub has taken the concept of ransomware to a more psychological and media-driven level.
They publish confidential information, they make public statements, use social networks and specialized forums to publicly humiliate victims and exert pressure not only technically, but socially.
A “brand” of fear
Ransomhub isn't hiding anything. It even has a kind of "portal" where they announce new victims, much like a corporate blog. The aesthetic, language, and strategy seem straight out of a marketing campaign: they create narratives, document attacks, and aim for virality.
Its objective is clear: turn every attack into an example,a warning to other companies. If an organization fails to pay, it not only loses its data but also has its name appear on a public list, alongside leaked files, internal documents, and even private communications.
The damage is not only economic, it is also reputational and, in some cases, irreversible.
Ransomhub malware: how it works and why it's a concern
The RansomHub malware combines classic ransomware elements with new infiltration and manipulation techniques. It usually accesses systems by exploiting known vulnerabilities,often through leaked credentials on the dark web or through social engineering. Once inside, the malware encrypts the data and sends a clear message: either you pay, or everything becomes public.
But, as we said before, what really distinguishes Ransomhub is how it exposes its victims:
- Publication of confidential documents on publicly accessible portals.
- Leveraging social networks and forums to amplify the damage.
- Indirect pressure through contact with customers, suppliers, or the media.
This approach has put many organizations on alert; the damage to the image can be even more costly than the rescue itself, but giving in to Ransomhub's pressure can be just as dangerous.
Are we prepared for this type of threat?
The question is not whether a group like Ransomhub can target a company, but when. . Today's hyperconnectivity and the use of multiple digital tools mean that any organization's exposure surface is constantly growing.
That's why it's essential to adopt cybersecurity strategies that go beyond reactive measures. This is where the CTEM (Continuous Threat Exposure Management) model comes into play, proposing a proactive and continuous approach to identify and mitigate risks before they escalate into real attacks.
How Kartos can help you against threats like Ransomhub
Kartos, Enthec's business solution, is designed specifically for this type of context. Its primary function is to offer an external, real-time view of an organization's cyber exposure status.
This translates into very concrete benefits:
- Early detection of leaked credentials, possible access points, or spoofed domains.
- Threat monitoring on the dark web and on channels commonly used by groups like Ransomhub.
- Automated alerts in the event of suspicious activities or information leaks.
- Clear and easy-to-interpret panels, designed to facilitate decision-making by the security team.
The goal is not to eliminate risk (something impossible), but to minimize exposure and react quickly and strategically to any warning signs.
Why is reputation now the main target?
Companies have invested in firewalls, antivirus software, and internal training, but many still neglect their external digital image. . Today, a poorly managed incident can become more visible and damaging than the technical attack itself.
Groups like Ransomhub have understood this perfectly. They are no longer just looking to make money, but to generate fear. Their power lies in their ability to hurt where it hurts most: the trust that customers and partners have in the company.
What you can do now to protect yourself
Beyond technical solutions, there are several key actions every organization should consider to reduce the impact of these types of threats:
Review and minimize exposure
Conduct regular audits of systems, users, and access points to ensure security and compliance. Review the publicly visible information and identify what an attacker could exploit for infiltration or extortion.
Implement constant external monitoring
Using cybersecurity solutions, such as Kartos enables organizations to stay informed about the outside world. This allows them to monitor what is being said about their company on the dark web, detect leaks early, and take action before they become public headlines.
Prepare a reputational response plan
In addition to the technical plan, it is essential to have a crisis communication strategy:. What is said? How is it said? Who is responsible to the media, clients, or partners? The speed and consistency of the message can make all the difference.
Ransomhub is not just malware; it's a message
When you ask yourself what Ransomhub is, the answer goes beyond malware. It's a new form of extortion, more sophisticated, more public, more dangerous,. and, above all, it's harder to manage if you're not prepared.
It's not enough to protect yourself from the inside. Today, it's essential to stay aware of what happens outside the company,. to consider how an attacker might perceive you, to understand their potential actions if they were to harm you, and to anticipate potential threats. In this sense, Kartos isn't just a security tool. It's a window to the other side of the mirror.

Digital consent: Why accepting conditions doesn't guarantee the security of your data
We live connected lives. We browse, download, share, and accept every moment we spend on the internet. And right there, with that quick click of "Accept terms and conditions," lies one of the biggest problems of the digital age: digital consent.
Do we really know what we're agreeing to? Do we understand the implications these seemingly small decisions have on our privacy?
Even though we virtually sign that invisible contract with every app or service we use, that doesn't mean we're truly protected. In fact, it's often just the opposite.
Qondar: The tool that helps you understand and protect your digital footprint
Before we discuss the intricacies of digital consent, it's worth pausing to introduce Qondar, our solution designed for people who want to better understand what happens to their data on the Internet and how to protect their digital footprint.
Qondar focuses on helping you continuously monitor your exposure to online threats, which is known in the cybersecurity world as CTEM (Continuous Threat Exposure Management).
In other words, Qondar gives you a real-time snapshot of what the internet knows about you, so you don't have to rely solely on the privacy promises of the platforms you use.
Want to know what information about you is circulating online? Discover how Qondar can help you regain control of your data.
What is digital consent really?
The digital consent is the authorization we give, usually with a click, for an app, service, or website to use our personal data. This can include everything from our location and browsing habits to our photos, contacts, or messages.
In theory, this consent should be free, informed, specific, and revocable.. In theory, this consent should be free, informed, specific, and revocable. However, in practice, these requirements are rarely met. How many times have you read the terms and conditions before accepting them? That's right, almost never.
The problem: Accepting does not always mean understanding
This is where comes in the concept of Digital informed consent.. Because it is not just about accepting but also doing so with full knowledge of the facts. And that means understanding what data is being collected, for what purpose, for how long, and who else may have access to it.
But the reality is different:
- Many terms are ambiguous or overly technical.
- Consent is presented in very long texts that are almost impossible to read without investing a lot of time.
- You can "accept all" with a single click, but to manage each permission, you'll need to make additional clicks, drill down through menus, read external policies, etc.
This is not accidental; it is called Dark patterns, and they are techniques designed to manipulate you into making decisions that benefit the company, not you.
Why doesn't digital consent guarantee security?
Even if you give your consent, that doesn't mean your data is secure. There are several compelling reasons for this:
1. Non-transparent third parties
The data you share with a platform often doesn't stay there and is shared with third parties:
advertisers, business partners, analytics platforms... And even if you agreed to the original terms of service, that doesn't mean you've approved what these third parties do with your data.
2. Security violations
Data breaches are becoming more frequent. According to the IBM report “Cost of a Data Breach 2024", the average cost of a data breach is $4.88 million,and often, the user doesn't even realize their information has been compromised. Digital consent, no matter how clear, doesn't protect against a cyberattack.
3. Policy changes
Many companies modify their privacy policies over timeand don't always communicate clearly. What you consented to in 2021 may have changed in 2025. And if you don't find out, your data may be being used in ways you never approved.
Digital informed consent is a basis, but not a guarantee
It's not about demonizing digital consent, but understanding it for what it is: a part of the process, not a solution.. Digital informed consent is a step toward transparency, but as long as we continue to grant permission without knowing what it means, we will continue to give up control.
And what can you do as a user?
Here are some practical recommendations:
1. Don't accept for the sake of accepting
Try to take a minute to read the key points before agreeing. If an app asks for access to your microphone or photos for no obvious reason, it's a red flag.
2. Use digital surveillance tools
That's where Qondar excels. With this solution, you can:
- To know what data of yours is publicly exposed.
- Receive alerts if your information appears in suspicious places (forums, dark web, etc.).
- Evaluate your digital exposure level and make informed decisions.
3. Review permissions periodically
On your phone, in your accounts, in your browser... From time to time, review what permissions you've granted and delete any that aren't necessary.
4. Be wary of freebies
When a service is free, the product is often you,. that is, your data. Consider whether it's worth giving up personal information in exchange for functionality you can get elsewhere, more securely.
Digital consent needs to evolve
We are at a time when legislation is advancing more slowly than technology.. Meanwhile, the user remains the weakest party in the agreement.
That is why Enthec is committed to solutions like Qondar, which inform and empower. It's not about viewing the digital environment as a negative space but rather making it fairer, safer, and more humane.
Digital consent should be a free and conscious decision, not a trap camouflaged in small print.
Your data is part of you, your reflection in the digital world, and as such, it deserves to be protected. Accepting terms and conditions should not be an act of faith but a conscious choice.. You need tools that help you see beyond the click to do that.
Start protecting your digital identity today with Qondar. Analyze your exposure and take control of your privacy. Contact us and discover everything you can do.

5 essential practices for protecting databases with high-value information
Data is one of a company's most valuable assets, and protecting a database is not just a recommendation but a necessity.
Leaks, unauthorized access, and targeted attacks are commonplace, and a compromised database can result in significant financial loss or irreparable damage to a company's reputation.
Whether we're talking about financial information, personal customer data, or intellectual property, the reality is there's no room for error. Databases are the digital heart of many organizations, and understanding how to protect a database effectively has become an essential part of any serious technology strategy.
It's worth considering a tool that can make a difference in protecting a database from external threats: Kartos, developed by Enthec. Kartos is a continuous cyber surveillance tool designed for businesses and is part of the Continuous Threat Exposure Management (CTEM) approach.
Do you want to know how to effectively protect a database? Join us as we explore 5 essential practices for keeping your most valuable digital assets safe.
1. Access control: less is more
One of the basic safety rules is providing the minimum necessary access.. Not all employees or collaborators need access to the entire database. Therefore, it is essential to implement a clear and strict privilege control policy.
How to put it into practice?
- Define user profiles according to responsibilities.
- Use multi-factor authentication (MFA) systems.
- Record and review access periodically.
- Automate the expiration of temporary permits.
Misconfigured access can open a direct door to attackers.. Therefore, it is advisable to audit this aspect regularly and apply the principle of least privilege.
2. Data encryption: an extra layer that makes the difference
Although it sounds technical, data encryption simply converts said data into an unreadable format for those without the proper password. And it's one of the pillars of protecting a database.
Two types of encryption you should consider
- Encryption at rest: Protects stored data, even if the server is physically accessed.
- Encryption in transit: protects information that travels between the database and users or applications.
Both are necessary, especially if you use sensitive or regulated data (such as medical, financial, or personal identifier information).
3. Secure and frequent backups
Nobody wants that day to come… but sometimes it happens: a system failure, a ransomware attack, or an unforeseen catastrophe. And if you don't have a recent backup, the consequences can be devastating.
Good backup practices
- Automate daily or weekly backups, depending on activity level.
- Store copies in separate environments (ideally in the cloud and on-premises).
- Periodically test the restoration processes.
- Make sure your copies are also encrypted and protected.
A well-executed backup is the lifeline that allows you to recover critical information and continue operating without too many setbacks.
4. Active monitoring and incident response
A key aspect of database protection is anticipating incidents and detecting warning signs before it is too late.
Cyberattacks don't always leave visible signs. In fact, attackers often infiltrate for weeks before being detected. That's why continuous monitoring is essential to alert you to unusual behavior.
This is where solutions like Kartos come into play.
Kartos stays ahead of threats by detecting data breaches or vulnerabilities exposed in public and hidden sources on the Internet. With this information, the security team can act proactively, avoiding greater damages.
In addition, an incident response plan, which defines roles, steps to follow, and internal and external communication in case something goes wrong, is highly recommended.
Rapid detection and response can distinguish between a scare and a major crisis.
5. Updates and patches: small gestures, big impact
Many cyberattacks take advantage of known bugs in the software,which could have been avoided with a simple update. However, these tasks are often postponed due to convenience or lack of planning... until it's too late.
Tips to keep everything up to date
- Turn on automatic updates whenever possible.
- Schedule regular reviews of critical patches.
- Prioritize updates to systems that manage sensitive data.
Outdated software is like a door that is not closed correctly: It seems safe, but anyone with bad intentions can get in.
Why is it so important to know how to protect a database?
The answer is clear: because data is the new gold.. Whether you run a small business or a large corporation, risks are present, and cyber criminals are relentless. Furthermore, current legislation (such as the General Data Protection Regulation or GDPR) requires active measures to safeguard the privacy and integrity of information.
By applying these five practices, you'll be taking concrete steps to reduce your risk exposure, comply with regulations, and maintain the trust of your customers and partners.
What if you don't know where to start?
Not all companies have technical teams capable of implementing these measures independently. That's why there are solutions such as Kartos by Enthec, which allows for complete visibility of the exposure risk without the need for a cybersecurity expert.
Kartos detects vulnerabilities in real time, prioritizes threats according to their risk level, and facilitates corrective actions—all from a clear, accessible dashboard designed for informed decision-making.
Knowing how to protect a database is no longer knowledge reserved solely for technical profiles: it is a cross-cutting priority that affects the entire organization, from IT to management. It is a strategic necessity for any company that values its digital assets. With good practices, appropriate tools like Kartos, and a proactive approach, it's possible to drastically reduce risks and anticipate problems before they occur.
Don't wait for a data breach to take action. Your data's security deserves constant attention and professional solutions.

Cybersecurity in hotels: key strategies for the sector
Cybersecurity in hotels has become an essential pillar of operational and reputational management in the tourism sector. As guest experiences become digital, from booking to checkout, the risks of cyberattacks, data loss, and fraud also increase.
It's not just about protecting a Wi-Fi network; we're talking about protecting sensitive information, such as thousands of customers' personal and financial data.
The hotel sector needs to adapt to new digital threats, incorporating proactive strategies, cybersecurity tools, and ongoing processes for reviewing their risk exposure.
This is where technological innovation comes into play, with solutions specifically designed to secure these businesses' digital infrastructure.
One of these solutions is Kartos.. This is not just a simple analytics platform but a Continuous Threat Exposure Management (CTEM) platform.. This means it helps businesses continuously identify, measure, and mitigate digital vulnerabilities, constantly assessing their exposure to real threats.
In the hotel industry, Kartos can detect everything from network breaches to leaked customer data on forums without requiring any implementation within hotel chains' complex internal structures.
Want to reduce your exposure to cyber threats before it's too late? Learn more about how Enthec and its Kartos platform can help to protect your hotel starting today.
Why is cybersecurity in hotels more critical than ever?
The digitalization of the tourism sector has brought great benefits, but has opened new doors for cybercriminals. A report by IBM Security revealed that the hospitality sector is one of the ten most attacked globally, mainly due to the volume of personal and financial information it handles.
Hotels often operate with legacy systems, insecure configurations, or outdated password policies. Added to this are connected devices, such as smart locks or IoT HVAC systems, which, if not adequately protected, become entry points for attackers.
And what are hackers looking for in a hotel?
- Customer bank details.
- Booking information and behavior patterns.
- Access to internal systems for identity theft or blackmail.
- Vulnerable infrastructure that can be used as a “bridge” for other attacks.
Trend in hotel cybersecurity: moving from reaction to prevention
One of the main trends in hotel cybersecurity is a change in focus. Previously, people waited for something to go wrong before acting. Today, the goal is to detect threats before they have consequences.
Continuous Threat Exposure Management (CTEM), powered by platforms like Kartos, is based precisely on that principle. It's no longer enough to perform audits once a year. What works is constant, agile, and frictionless control, which allows for the detection, classification, and addressing of each vulnerability in a prioritized manner.
In this sense, CTEM solutions such as Kartos allow:
- Monitor the hotel's digital display 24 hours a day.
- Detect leaked credentials in real time.
- Analyze subdomains, DNS settings, and information leaks.
- Receive personalized alerts based on the level of criticality.
Specific challenges of cybersecurity in hotels
Cybersecurity in hotels presents unique challenges that go beyond the typical technological challenges of any business. Every establishment must face risks that evolve at the same pace as guest connectivity and operational demands.
Multiplicity of devices and entry points
The attack surface is vast, including computers, servers, POS terminals, IoT devices, and employee and customer smartphones. If not correctly monitored, any misconfigured device can be a gateway.
Rotating staff and insufficient training
The high level of staff turnover in many establishments makes it challenging to implement strong cybersecurity protocols. . Without proper training, employees can easily fall for phishing attacks or handle sensitive information without the necessary precautions.
Open Wi-Fi networks
Although offering free Wi-Fi to guests is a standard service, many hotels do not segment their networks properly, which can compromise the security of clients and internal systems.
Highlighted strategies to strengthen hotel cybersecurity
To address the above challenges successfully, a clear and realistic roadmap must be designed. The key is to combine technology, processes, and corporate culture, always with an eye toward the guest experience and the business's reputation.
1. Implement a CTEM system like Kartos
Incorporating a Continuous Threat Exposure Management solution allows for an updated map of the hotel's security status,allowing quick action and staying ahead of cybercriminals. Kartos, in particular, is designed to operate without interfering with the hotel's internal systems, making it easier to adopt and maintain.
2. Continuous staff training
It is not enough to install software: the first line of defense is people.. Training your team on best practices, recognizing fraudulent emails, and responding to incidents is essential. Some companies even organize cyberattack simulations to reinforce this knowledge.
3. Segment networks and apply access policies
Separating the hotel's customer network from its operational network is a basic, yet often overlooked, step. Furthermore, employees should only have access to the information and systems they need.
4. Backup and recovery policies
Having encrypted backups and a well-defined recovery plan can be the difference between a scare and a catastrophe. Especially in ransomware attacks, having up-to-date backups allows you to get back to business quickly without giving in to blackmail.
5. Active monitoring of exposed assets
One of Kartos's most innovative aspects is its ability to detect digital assets exposed on the public network.. From vulnerable IP addresses to misconfigured cloud documents, each finding is presented with an associated criticality and remediation advice.
What if your hotel has already been the victim of an attack?
It's not always easy to detect. Sometimes, stolen data is sold or used months later. That's why one of Kartos' standout features is the ability to conduct cyber surveillance in open sources and forums, where leaked data often appears. You can act quickly to contain and respond to the incident by identifying any mentions related to your domain.
In an environment where reputation is everything, a security breach can mean much more than a fine or a financial loss. It can translate into customers who don't return, negative comments, and loss of trust in the brand.
From Enthec, with our Kartos platform, we offer hotels a practical, immediate, and proactive way to manage their digital security through technology designed to be used by large chains and independent hotels that want to protect their business without complications.

Taking care of your guests also starts with protecting their data.
Google bombing: How to defend your digital reputation against this type of attack
A Google search can define who you are, what you stand for, or whether someone trusts you. What appears on the first page of results can significantly impact your digital reputation, whether you're an individual or a business. This is where a little-known but highly damaging phenomenon comes into play: Google bombing.
Although its name sounds distant or technical, its consequences can be felt very close at hand. Google bombings in Spain, as in other countries, have been used to damage public images, manipulate opinions, or even attack professionals and companies without them being aware of what is happening.
What is Google bombing?
The term Google bombing refers to a technique for manipulating search results on Google. It involves linking certain keywords to a specific page to artificially alter its position in the results.
Let's imagine that many websites link the phrase "corrupt company" to a specific company's website. Over time, Google may eventually show that company as the first result when someone searches for that phrase. It doesn't matter if the content is fake or the link lacks context; the algorithm doesn't judge intentions; it only interprets signals.
This technique, which began as a form of political joke or protest in the early 2000s, has evolved into a tool for digital defamation. It is often silent and difficult to detect until it's too late.
Who can it affect?
Any person or entity with a digital presence is susceptible to Google bombing. This includes politicians, public figures, entrepreneurs, independent professionals, SMEs, and even anonymous users who, due to a specific conflict, are targeted by this type of campaign.
Although not always reported in the media, cases of Google bombing have been on the rise in Spain. Just look at forums, social media, or anonymous smear campaigns that go viral and negatively affect search results.
The problem is that reputational damage can have real consequences: loss of customers, cancellation of contracts, deterioration of personal branding, and even legal problems.
Why is it so difficult to detect it in time?
One of the big challenges of Google bombing is its ability to go unnoticed.. Unlike a direct attack, such as hacking or online insults, this technique works by accumulating links, many on seemingly harmless pages or those created explicitly for that purpose.
By the time an affected person realizes it, the content has already taken root, and reversing the damage is much more complex.
Furthermore, Google doesn't automatically respond to these cases, except in obvious manipulation cases. Reporting content doesn't guarantee its disappearance or that the associated results will be removed. Therefore, prevention and continuous monitoring are fundamental to maintaining control of your online presence.
The importance of personal cyber surveillance
Given this situation, Continuous Threat Exposure Management (CTEM) is becoming an essential tool. A good antivirus or avoiding suspicious links is no longer enough; today, protecting your image on search engines, social networks, and digital forums is equally essential.
This is where our solution appears. Qondar, is designed for individual cyber-surveillance.. While other platforms are designed only for large companies, Qondar focuses on protecting individuals, whether professionals, freelancers, or citizens concerned about their online reputation.
This solution automatically analyzes what is said about you on the Internet, detects patterns of suspicious behavior, identifies potential smear campaigns, and alerts you if there are signs that someone is trying to manipulate the results associated with your name.
How to defend yourself against Google bombing?
Although Google bombing has become less effective, a site can still be affected. To defend yourself, it's important to remember the following recommendations.
1. Monitor your digital footprint regularly
A Google search for your name or your company's name should be part of your routine. Do it from different devices, logged in, and in incognito mode. What pops up? Is there anything odd? Are negative phrases being repeated on unfamiliar websites?
If you notice a sudden change or a strange association of your name with offensive terms, you could be a victim of Google bombing.

2. Act quickly: prevention is better than a cure
The sooner you detect an attack, the easier it will be to stop it. You can start by:
- Report suspicious links to Google.
- Request the removal of defamatory content from the page administrators.
- Generate positive and truthful content (posts, interviews, blogs, optimized profiles, etc.) that improves your natural positioning.
In more severe cases, a solution like Qondar may be enough to prevent serious repercussions, such as a far-reaching reputational crisis.
3. Don't fight alone: surround yourself with tools and professionals
The reality is that no one is 100% protected. Not even the biggest brands. But having a strong digital shield helps a lot. In addition to Qondar for individuals, Enthec offers Kartos, our platform for businesses and organizations, which is also focused on continuous digital threat management.
These solutions allow you to detect not only Google bombing but also information leaks, improper mentions, or more sophisticated attack patterns.
What if you've already been a victim?
In that case, the key is to reverse the impact.. Here are some actions:
- Positive positioning: Work on publishing content that displaces negative results. Search engines value relevance and authority, so it's essential to feed your footprint with legitimate and quality content.
- Legal assistance: You can contact digital law experts if the published content is false or defamatory. In Spain, favorable case law in cases of online reputation attacks is increasing.
- Technical reports: Tools like Qondar can generate reports supporting complaints or legal proceedings, demonstrating that a coordinated strategy was used to harm you.
From Enthec, we work with solutions like Qondar so that each person can have control of their online presence.. Because protecting your digital identity on the Internet shouldn't be a lonely battle.
Why DNS health is critical to your company's cybersecurity
Digital threats are evolving faster than ever. Companies, large or small, cannot afford to look the other way when it comes to protecting their digital infrastructure. Here is one aspect that is often overlooked, yet is key to digital security: DNS health.
But what does this mean exactly? And why is it so important to control DNS health within the strategy of business cybersecurity?
Before we dive in, let's make a crucial point. If your company doesn't yet have Continuous Threat Exposure Management (CTEM) tools, you may be leaving windows open to the outside without realizing it.
This is where Kartos, our solution for cyber surveillance for companies,specifically designed to detect, assess, and continuously reduce your organization's digital exposure, appears. Kartos not only monitors your digital attack surface but also allows you to protect your DNS and detect related vulnerabilities before attackers exploit them.
What exactly is DNS health?
When discussing DNS health, we refer to the security status, configuration, and maintenance of an organization's domain name system. DNS acts as a “phone book” for the internet: it converts domain names (like enthec.com) into IP addresses that machines can understand.
A secure DNS server isn't just a technical issue; it's an essential pillar of your digital defense. Cybercriminals can exploit a misconfigured DNS to carry out attacks such as:
- Pharming: redirect your employees or customers to fake websites.
- DNS hijacking: hijack your web traffic for espionage or fraud.
- DDoS through DNS amplification: take advantage of your DNS as a vector to saturate other servers.
These risks affect large corporations as well. SMEs are also frequent targets precisely because they neglect aspects like this.
Why do so many companies ignore DNS health?
There are several reasons, but one of the main ones is the false sense of security.. Many organizations believe they are protected by having antivirus systems or firewalls. However, these devices do not monitor or manage your domain name system configuration.
On the other hand, DNS is usually managed by third parties (such as hosting or domain providers), which means that, despite being a critical element, companies do not include it in their security audits.
What does it mean to have good DNS control
Having effective DNS control means keeping a series of good practices active and up-to-date. These include:
- Audit your DNS records and detect outdated or unnecessary settings.
- Ensure your SPF, DKIM, and DMARC records are correctly configured to prevent email phishing.
- Use secure and redundant DNS servers.
- Protect access to your DNS management with strong authentication.
- Monitor unauthorized access attempts or changes.
These steps are essential to ensure a business environment free of invisible breaches.
Kartos and continuous DNS monitoring
This is where Kartos comes into play. It proactively monitors your DNS status and alerts you to any suspicious changes. It's not just about protecting them but anticipating the future.
Kartos allows you:
- See your digital display surface in real time.
- Detect uncontrolled or misconfigured assets (including DNS and subdomains).
- Prioritize vulnerabilities with an approach based on real risk.
- Receive early warnings on possible attack vectors involving DNS.

Comprehensive, continuous management distinguishes a company that reacts to an attack from one that neutralizes it before it occurs.
How do you know if your DNS server is secure?
Some tools allow for spot checks, but that's not enough. The digital environment changes daily, and attackers find new ways to exploit weaknesses. Therefore, a CTEM solution like Kartos is essential.
Kartos not only tells you if your DNS is secure now but also helps you maintain that security continuously.. This includes automated analysis, detailed reporting, and remediation suggestions tailored to your technological reality.
Practical recommendations to improve your company's DNS health
If you don't yet have a solution like Kartos, we recommend that you at least consider the following points:
- Update your DNS records frequently. Discard any unused items. frequently. Discard any unused items.
- Activate DNSSEC to protect the integrity of queries.
- Audit your SPF, DKIM, and DMARC registers with the help of specialists.
- Avoid using public DNS servers as the principal solution.
- Control who has access to your DNS console.. Not all technicians need to have full permissions.
The good news is that it's never too late to improve your organization's DNS health.
Neglecting your digital infrastructure's DNS health can have serious financial and reputation consequences. DNS control and a secure DNS server should be at the heart of any modern cybersecurity policy.
With our solution, Kartos, you are protecting your DNS and taking a step towards a smarter, more preventative, and continuous security model.
