Defguard combines WireGuard® VPN with protocol-level multi-factor authentication, SSO/IdP integration, firewall policy orchestration, and a built-in identity provider into a single self-hosted platform.
It supports external identity providers (Google Workspace, Microsoft EntraID, Okta, JumpCloud, LDAP/AD) and enforces zero-trust principles at the network layer.
Built in Rust for memory safety, it offers full audit logging, SIEM streaming, and public security audits.
The core product is fully open source; advanced enterprise features (HA, device attestation, SIEM streaming) are available on paid tiers.
Developed and headquartered in Poland, it explicitly targets ISO 27001, NIS2, GDPR, and HIPAA compliance requirements.
