Authentik: sovereignty score and 8 European alternatives

authentik is an open-source identity provider (IdP) for single sign-on. It supports OAuth2/OIDC, SAML, LDAP, SCIM and RADIUS, and offers multi-factor authentication including WebAuthn (passkeys), conditional access and an application proxy, and it can federate with external sources. It is designed for self-hosting, from small setups to large production clusters, and is installed with Docker Compose or Kubernetes (Helm). Alongside the free open-source version there is an Enterprise version, offered as source-available software with additional features and a support centre.

authentik is developed by Authentik Security Inc., a public benefit company launched by Open Core Ventures. The core of the code is under the MIT licence; code in the enterprise directory has a separate licence. According to the sources consulted, the vendor does not run a hosted cloud service of its own, so you run authentik yourself on infrastructure of your choice, for example in a European data centre, and the data stays within your environment. Dependence on the vendor is then limited to the software and any enterprise support.

Why digital sovereignty matters with Authentik

Authentik is headquartered in the United States. US vendors fall under the CLOUD Act and FISA 702: US authorities can compel access to data, even when that data sits in a European data centre. That is the core of the jurisdictional exposure in our model.

Data is hosted exclusively in the EU, so Authentik scores best on data residency.

Authentik is open source. You can audit the source code, self-host the software and keep the encryption keys under your own control. Switching is easier because data and software are not tied to a single party.

What this means for your organisation depends on your whole stack and context. The free assessment weighs Authentik together with your other vendors and gives a total score, a heatmap and the main risk drivers.
