 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](https://www.wireguard.com/)**, and how open-source VPN management solutions like **[Defguard](https://defguard.net/)** facilitate MFA integration in WireGuard environments—while also providing functionalities like identity management, Single Sign-On (SSO), and hardware key management.
