-Organizations seeking compliance with the NIS2 Directive can leverage Multi-Factor Authentication (MFA), not just as a regulatory checkbox but as a crucial layer of defense in their cybersecurity strategy. In this article, we’ll explore how MFA supports NIS2 compliance, the advantages of implementing MFA in modern Virtual Private Network (VPN) systems like WireGuard, and how open-source VPN management solutions like Defguard facilitate MFA integration in WireGuard environments—while also providing functionalities like identity management, Single Sign-On (SSO), and hardware key management.

 ## Understanding the NIS2 Directive
 
 The NIS2 Directive (Network and Information Security Directive) builds upon its predecessor (NIS Directive) with more stringent requirements aimed at bolstering the cybersecurity resilience of critical infrastructure sectors, including energy, transport, health, and financial services. It mandates that organizations implement stronger security measures to protect networks, systems, and data. A key component of NIS2 is the focus on MFA.
 
-MFA provides an additional layer of security by requiring users to present two or more verification factors to access a system. According to the 2025 Verizon DBIR, around 60% of all breaches involved the human element, including stolen credentials, making MFA a critical defense against common attack vectors.

 ## The Role of MFA in NIS2 Compliance
 
-Multi-factor authentication is emphasized in the NIS2 Directive for several reasons. First, it helps mitigate the risks associated with compromised passwords. MFA strengthens the security of authentication processes by requiring more than just a password, thus making it more difficult for malicious actors to gain unauthorized access to sensitive systems.

 For organizations, MFA provides several security advantages:
 * **Strengthening access control:** MFA makes it exponentially harder for attackers to breach systems, even if they manage to steal a user’s password.
