Univention
EU verifiedGerman open-source IAM platform (Univention Corporate Server) for identities, SSO and app integration – self-hostable, strong on sovereignty.
Univention (Univention GmbH, Bremen) develops the Univention Corporate Server (UCS) – an open-source all-in-one platform for identity and access management, user and device management and app integration. UCS is based on Debian and integrates proven open-source building blocks like OpenLDAP, Samba and Kerberos; the modern IAM solution Nubus is built entirely on open source and open standards, so no proprietary dependencies arise. Univention is strongly focused on digital sovereignty and is established in the public sector and at large organisations. This makes UCS a European, self-hostable alternative to Auth0/Okta and Microsoft Active Directory setups.
