Cybersecurity is no longer the exclusive domain of technical departments; it has become a strategic priority for all companies, regardless of their size and scope. Cyberattacks have become increasingly sophisticated, and criminals are no longer just after financial data; they are also targeting confidential information, login credentials, internal plans, and any digital trace that can be used for their own benefit.
In this scenario, protecting user accounts with a simple password is no longer sufficient:
phishing attacks,
credential theft, and password reuse make it essential to strengthen access controls.
Today, we want to discuss multi-factor authentication (MFA), an additional layer of security that can be a valuable ally in preventing
security breaches
.
Before delving into the details of how it works, it is worth mentioning Kartos, the solution for Continuous Threat Exposure Management (CTEM) developed by Enthec. Designed for businesses, Kartos enables organizations to continuously understand their exposure to potential digital risks, detect vulnerabilities, and anticipate attacks before they occur.
Multi-factor authentication is a fundamental step in this overall protection strategy, as it reduces the attack surface at one of the most critical points: access to accounts and systems.
What is MFA, and why is it so important?
To understand the need for this system, it is helpful to answer the question: What is MFA? Multi-factor authentication is an identity verification method that requires the user to present two or more pieces of evidence before accessing a digital resource. Simply put, a regular password isn’t enough; you need to provide one or more additional verifications.
These tests are based on three main categories:
- Something you know: a password, PIN, or security question.
- Something you have: a code sent to the mobile phone, a physical token, or an authentication application.
- Something you are: facial recognition, fingerprint, or voice.
When we combine at least two of these categories, the chance of a cybercriminal gaining access, even if they steal the password, is drastically reduced.
Examples of multi-factor authentication
Although it may seem like a complicated technology, the reality is that we use it almost unconsciously in our daily lives. Some common examples of multifactor authentication are:
- Access to online banking: In addition to your password, you receive a code via SMS or an authentication app.
- Corporate email: The company requests a temporary code generated by an app such as Google Authenticator or Microsoft Authenticator.
- Social networks and cloud services: You are asked to confirm access from your own mobile device.
These examples of multi-factor authentication demonstrate that its use not only increases security but has also become a natural practice, accepted by both users and organizations.
Main benefits of multi-factor authentication in companies
Implementing an MFA system not only translates into a higher level of security but also into multiple advantages that affect the business as a whole.
1. Reducing the risk of credential theft
Password theft is one of the most common techniques used in cyberattacks. With MFA, even if attackers gain access to your password, they will still need a second factor to gain access.
2. Regulatory compliance
Increasingly, data protection regulations, such as the General Data Protection Regulation (GDPR) or the National Security Scheme (ENS) in Spain, recommend or even require additional authentication mechanisms. Implementing MFA helps meet these standards.
3. Trust and reputation
Customers and partners appreciate a company’s commitment to security. Adopting measures such as multi-factor authentication helps build trust and strengthen the company’s image in the market.
4. Lower long-term costs
Although implementing MFA involves an investment, the truth is that preventing a security breach can save thousands of euros in fines, data loss, and reputational damage.
5. Flexibility and adaptability
Today, there are multiple MFA solutions, from SMS to advanced biometrics. This allows companies to choose the option that best suits their size, sector, and needs.
Multi-factor authentication and CTEM: a necessary combination
Multi-factor authentication is just one piece of a much larger puzzle: that of continuous threat exposure management (CTEM).. Adopting MFA protects access, but security must go further.
This is where solutions like Kartos can help your business. Kartos not only helps implement security controls but also provides a constant view of the company’s digital attack surface, detecting potential weak points and facilitating a rapid response to any threat.
There’s little point in implementing multifactor authentication if we don’t know what other entry points might be open. That’s why the CTEM approach is so valuable: it anticipates, monitors, and mitigates risks in real-time, integrating measures such as MFA into a comprehensive global cybersecurity strategy.
Common obstacles and how to overcome them
Not all companies take the step immediately. Among the most common barriers to implementing MFA are:
- Employee resistance:Some individuals view MFA as an additional step that complicates access to accounts. The key is communicating the benefits and choosing simple methods, such as mobile apps.
- Initial cost:Although there are very cost-effective solutions, some companies perceive the investment as a hindrance. However, compared to the price of a security breach, MFA is much more cost-effective.
- Integration with legacy systems:In organizations with outdated software, this can be more difficult. However, some integrators and solutions allow for gradual adaptation.
Experience shows that these obstacles can be overcome through training, awareness, and the strategic use of technology.

The future of multi-factor authentication
Everything suggests that MFA is evolving toward even more convenient and secure methods. Biometrics, physical security keys, and artificial intelligence-based solutions will mark the next stage. There’s even talk of a passwordless future, where authentication will be based on stronger, harder-to-fake factors.
For businesses, adopting MFA today is a step forward toward tomorrow’s security. . It’s not just a tool for the present, but the foundation on which the future of digital protection will be built.
Multi-factor authentication is not a fad or an optional extra: it is a necessity for any company that wants to protect its information, comply with regulations, and instill confidence in its customers. Integrating it into a broader security strategy, such as the one offered by Enthec’s Kartos through its CTEM approach, is the best guarantee that corporate access will be protected against attacks.
In an environment where cyberattacks are becoming increasingly frequent, failing to act promptly can be costly.. If your organization still relies solely on passwords, it’s time to strengthen security.
