didmos: sovereignty score and 8 European alternatives

didmos is a modular framework for identity and access management (IAM) from DAASI International GmbH. According to the vendor, it consists of open-source modules that can be adapted to your infrastructure. These include a user interface with a workflow engine for administration and self-service, an authentication component for SSO via SAML and OpenID Connect, federation tools, a module that synchronises password changes from Active Directory, an ETL module for identity sources, a provisioner for target systems and a core with a SCIM v2 API. DAASI also offers support and hosting, including a SaaS option.

DAASI International GmbH is based in Tübingen, Germany, and the pages consulted name no foreign parent company. The source code of the modules is published in the company's GitLab, and a user community runs mailing lists. Which licence applies could not be established from the pages visited, so ask the vendor. DAASI does not state where its hosted offering runs. When you operate didmos yourself, you decide the data location; with hosting, it is worth having the location confirmed in writing beforehand.

Why digital sovereignty matters with didmos

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

didmos runs on infrastructure you choose and control yourself. You decide where the data lives, including fully within the EU if you want — this is not a fixed hosting choice made by the vendor.

didmos is closed source, but you run the software yourself on your own infrastructure. The encryption keys and the runtime therefore stay under your own control, though you cannot audit or modify the source code. Ask about export options and open standards to limit software-level lock-in.

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