Defguard is an open-source, Rust-built WireGuard VPN manager that adds multi-factor authentication, an identity/SSO gateway, and a web UI for managing peers, gateways, and access policies. It's built for teams that want a self-hosted, enterprise-grade WireGuard mesh without relying on a third-party cloud control plane, and it ships both a free open-source edition and a paid enterprise tier.

Who it's for

Defguard is aimed at organizations that need to give employees and network devices remote access to internal infrastructure - IT/security teams replacing legacy SSL-VPN or hardware VPN appliances (Cisco, Fortinet, SonicWall) who want a self-hosted, WireGuard-based access control plane rather than a third-party cloud VPN service.

What you get

A self-hostable WireGuard VPN control plane with a built-in OpenID Connect identity provider, connection-level multi-factor authentication (TOTP, email OTP, biometrics, hardware keys), LDAP/Active Directory sync, firewall-style access control lists, activity and audit logging with SIEM streaming, and desktop (Windows/macOS/Linux) plus mobile (iOS/Android) clients. External SSO login (Google, Microsoft, Okta, JumpCloud) and some higher-end features (ACLs, high availability, SIEM streaming) sit behind the paid Business/Enterprise tiers.

How it works

Administrators deploy a Core component (identity, users, configuration) inside their private network, a stateless Proxy component with the only public endpoint used for enrollment/onboarding, and one or more Gateway components that terminate WireGuard tunnels for defined VPN 'Locations'. Desktop and mobile clients enroll via a token-based process, receive their WireGuard configuration automatically, and can be required to complete MFA at the protocol level before a tunnel is established; per-location Allowed IPs and firewall rules then control which internal subnets each client can reach.
