Defguard

Defguard is an open-source, zero-trust enterprise VPN that embeds native multi-factor authentication directly into the WireGuard protocol and unifies VPN, identity (OIDC/SSO/LDAP/AD) and fine-grained Access Control Lists in a single platform. It supports on-premise or private-cloud deployments, extensive API/webhook automation, and compliance features (SOC 2, NIS2, HIPAA), delivering secure remote access with full data sovereignty.
