Defguard is an enterprise VPN solution built on the WireGuard protocol, offering secure remote access with integrated identity management. It enforces multi-factor authentication at the protocol level, ensuring connection-level security and compliance with regulatory standards while mitigating MFA bypass risks. The platform streamlines secure access through user and device management, live configuration updates, audit logs, and restricted access to official clients. As an OpenID Connect identity provider, Defguard integrates with SSO platforms like Microsoft Azure AD, Google Workspace, and others. Fully self-hostable and privacy-focused, Defguard provides organizations with complete control and transparency over their infrastructure. Built in Rust, this open-source solution delivers modern, auditable security for remote access without relying on third-party dependencies.
