Add Zero Trust Protection to Authentik Admin — Shield Your Identity Platform with Defense in Depth

Overview

Why Authentik Needs an Authenticated Proxy

Authentik is a modern open-source identity provider supporting SAML, OIDC, LDAP, SCIM, and proxy authentication. Like Keycloak, the Authentik admin interface is the crown jewel of your identity infrastructure — controlling user accounts, authentication flows, application registrations, and identity federation. OnePAM adds defense-in-depth by requiring separate authentication before administrators can reach the Authentik admin interface, ensuring that even compromised Authentik credentials or zero-day vulnerabilities cannot be exploited without first passing OnePAM's identity check.

HTTP Header Authentication

X-Forwarded-User

OnePAM authenticates administrators via a separate identity verification before proxying requests to Authentik's admin interface. User-facing authentication endpoints remain directly accessible.

Zero-Day Risk Profile

Authentik Vulnerability Risks

Without an authenticated proxy, these risks are directly exploitable by any network-reachable attacker.

Authentik admin controls all user identities and authentication flows

Application client secrets and SAML certificates are accessible from admin

Flow and policy changes can weaken security for all connected applications

User impersonation features in admin can bypass all access controls

The Challenge

Security Challenges with Authentik

These are the risks organizations face when Authentik is not behind an authenticated proxy.

Identity Infrastructure Risk

The Authentik admin interface controls your entire identity infrastructure — user accounts, authentication flows, and application registrations.

Single Auth Layer

Protecting the admin interface with only Authentik's own authentication means a single credential compromise grants total control.

Impersonation Risk

Authentik's admin impersonation feature allows admins to act as any user — a powerful tool that requires the highest security.

Flow Tampering

Authentication flow modifications can silently weaken or bypass security for every connected application.

CVE Exposure

As a complex identity platform, Authentik may have vulnerabilities that expose the admin interface to attack.

Admin Activity Auditing

Tracking admin configuration changes requires robust external audit logging.

The OnePAM Solution

How OnePAM Adds SSO + Zero-Day Protection to Authentik

A step-by-step guide to deploying OnePAM's authenticated proxy in front of Authentik.

Deploy OnePAM for Admin Paths

Configure OnePAM to protect Authentik's admin interface paths.

User-facing login, SAML, and OIDC endpoints remain directly accessible. Only admin paths require OnePAM authentication.

Configure Separate Authentication

Connect OnePAM to a separate IdP or use additional authentication requirements.

Defense in depth: admin must authenticate via OnePAM SSO before reaching Authentik's admin login.

Enforce Hardware MFA

Require FIDO2 or hardware token authentication for admin access.

Even compromised admin passwords are useless without the physical security key.

Restrict Admin Access

Only IAM team members from trusted networks can access the admin interface.

IP restriction, device trust, and IdP group policies limit admin access.

Record Admin Sessions

Full visual recording of every admin session for compliance and forensics.

Track who modified flows, changed policies, or impersonated users.

Frequently Asked Questions

Authentik SSO + Security FAQ

Common questions about deploying OnePAM's authenticated proxy for Authentik.

Does OnePAM affect Authentik's user-facing SSO?

No. OnePAM protects only the admin interface. User-facing login, SAML, OIDC, and LDAP endpoints remain directly accessible for normal application authentication.

Why add OnePAM if Authentik has its own authentication?

Defense in depth. If Authentik admin credentials are compromised or a CVE affects the admin interface, OnePAM's separate authentication layer prevents exploitation.

Does OnePAM work with Authentik's Docker deployment?

Yes. OnePAM can proxy to Authentik containers in Docker or Kubernetes environments.

Can OnePAM use Authentik itself as the IdP?

Yes, though for maximum security, using a separate IdP for OnePAM admin authentication provides better defense in depth.

Does OnePAM support Authentik's proxy provider?

OnePAM can coexist with Authentik's proxy provider. Each serves different use cases — OnePAM protects the admin interface while Authentik's proxy protects downstream applications.
