XignSys: sovereignty score and 8 European alternatives

XignSys supplies software for digital identities and access management. Its XignIn technology consists of a server component (XignIn Manager), an SDK for Android and iOS, and the Xign.Me app, which lets users sign in with their smartphone without a password. The company also offers customer identity and access management based on Keycloak and an ID broker for German public services, which connects applications to BundID, ELSTER and the EUDI wallet through a single OIDC or SAML interface. According to the vendor, the broker does not permanently store personal identity data.

XignSys GmbH is headquartered in Gelsenkirchen, Germany, and the pages consulted name no parent company. The vendor states that the ID broker runs as a managed service in a German, certified cloud or, on request, on-premises in the customer's own infrastructure, and that it builds on open-source components such as Keycloak. For European organisations, particularly in the public sector, this means a German supplier with no foreign parent named, where processing can stay within Germany.

Why digital sovereignty matters with XignSys

XignSys 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.

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

XignSys is closed source and hosted by the vendor. The encryption keys and the runtime sit with the vendor and switching requires data migration. Ask about bring-your-own-key, export options and open standards.

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