Switzerland's federal government has launched a pilot program to replace Microsoft 365 with open source alternatives across 3,000 workstations. That's about 7% of the federal workforce. The target is to complete the migration by end of 2027.
This move follows a successful proof-of-concept and a new digital sovereignty law. A separate fast-track military migration is also already underway.
According to Matthias Stürmer, professor at the Bern University of Applied Sciences (BFH), Microsoft’s supremacy in public institutions poses three problems that are driving this migration.
First is the risk of foreign access. US cloud legislation could expose Swiss government data to foreign authorities.
Second is the risk to service continuity, as dependency on a single foreign vendor creates operational risk.
The third risk is the escalating costs as proprietary licensing fees are rising with no Swiss leverage.
Switzerland's military cybersecurity unit, Cyber Command, is not waiting for the civilian pilot. It is already poised to replace Microsoft 365 entirely with openDesk by October 2026.
It is pretty much the same reason. Military doesn't want foreign governments accessing sensitive Swiss data.
