Defguard

Defguard is an enterprise-grade zero-trust access management platform centered on WireGuard VPN with multi-factor authentication enforced at the VPN protocol level. It also provides integrated identity and SSO capabilities, designed for auditable, private deployments without relying on third-party cloud services.

Key Features

• WireGuard VPN with true connection-level 2FA/MFA (TOTP/email tokens, pre-shared keys) rather than web-only MFA
• Built-in OpenID Connect identity provider for SSO, plus support for external OIDC providers
• LDAP/Active Directory integration with synchronization for users and groups
• User, device, and group management with policy controls (RBAC-style administration)
• Remote user enrollment and onboarding flows, including client configuration distribution
• Forward-auth support for protecting applications behind reverse proxies
• Audit-focused operations with logs and visibility into connected users/devices

Use Cases

• Secure remote workforce access to private networks using WireGuard with enforced MFA
• Replace or complement an existing IdP by acting as an OIDC provider for internal apps
• Centralize user/device onboarding and access policies for multi-site VPN deployments

Defguard fits organizations that need a modern WireGuard-based VPN with strong identity and access controls, while keeping authentication and configuration fully under their own infrastructure.
