Overview

Authentik is a self-hosted, open-source identity provider. The open-source project began in 2018, and it is now developed commercially by Authentik Security Inc., founded in November 2022. It gives organizations a way to manage authentication and access to applications without depending on a third-party identity service.

Key Features

Authentik supports OAuth2/OIDC, SAML2, SCIM, LDAP, RADIUS, and Kerberos protocols, along with an application proxy for remote access to services like RDP, VNC, and SSH. It includes multi-factor authentication, WebAuthn/Passkeys, conditional access policies, and GeoIP/impossible-travel detection.

The platform can be deployed via Docker Compose or Kubernetes, and workflows can be customized through APIs and infrastructure-as-code tools such as Terraform.

Pricing

The open-source core is free and self-hosted. A paid Enterprise tier starts at $5 per internal user per month (plus $0.02 per external user per month, billed annually) and adds integrations like Google Workspace and Microsoft Entra ID, mTLS authentication, and ticket-based support. An Enterprise Plus tier starts at $20,000 annually with dedicated SLA support and FIPS compliance.
