At the Univention Summit in the Congress Centrum Bremen, software manufacturers, IT service providers and users once again came together in 2025 for two days to discuss trends, challenges and requirements for digital sovereignty with open source.
Keynotes by internationally renowned speakers, one panel discussion, best-practice presentations, user reports, workshops and a technology barcamp offered a wealth of exciting content and opportunities for participation for the around 500 participants on site in Bremen. In addition, the exhibition with 40 software manufacturers and IT service providers offered plenty of time for exchange and networking.
