FusionDirectory: sovereignty score and 8 European alternatives

FusionDirectory is open-source identity and access management (IAM) software aimed at universities, research institutions and public organisations. According to its makers it offers a manageable administration interface, templates that define how directory objects are created, workflows that reduce manual steps, and delegation so that administration tasks can be handed to other users or groups. It supports the SupAnn standard used in French higher education, and it also covers user account lifecycle management. You install FusionDirectory yourself; a marketplace exists for extensions.

FusionDirectory is developed by a small team whose contact address is in Brussels, Belgium. The source code is published under a GPL licence, so it can be inspected and modified. Besides the software, the team offers service subscriptions, training, proofs of concept and change-management support; the website does not mention a hosted service of its own. If you run FusionDirectory on your own servers, identity data stays in your own environment and you decide where it is located.

Why digital sovereignty matters with FusionDirectory

FusionDirectory is headquartered in BE and therefore falls under European law: the GDPR, NIS2 and the Data Act. No foreign legislation can compel access to your data.

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

FusionDirectory 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 FusionDirectory together with your other vendors and gives a total score, a heatmap and the main risk drivers.
