Open Source Summit Europe: digital sovereignty moves to plans and metrics

Digital sovereignty dominated Open Source Summit Europe 2026, with talks on CRA compliance, OSPO value metrics and EU public-sector migration to open source. Berlin aims to make 70% of the software stack on administrative workstations open source by 2032.

• Berlin targets 70% open source in the software stack on administrative workstations by 2032
• CRA: reporting on actively exploited vulnerabilities is live, main requirements apply from December 2027
• Japan's IPA studied 30,000+ GitHub repos across 7 countries: many talk open source, few adopt it
• SUSE outlined the SEAL scale from SEAL-0 (no sovereignty) to SEAL-4 (full EU digital sovereignty)
