The Swiss Federal Chancellery has formally launched a sovereign workplace software program, marking the country's most concrete step yet toward reducing reliance on Microsoft 365 within government.

The program, announced by the Chancellery, aims to develop an open-source alternative to Microsoft's office productivity suite for deployment across critical federal roles. It targets approximately 3,000 users by the end of 2027, with the sovereign platform running in parallel alongside Microsoft 365 rather than replacing it outright in the first phase.

The initiative is backed by 9 million Swiss francs in initial funding, drawn from parliamentary appropriations for an open-source office automation platform. A feasibility study — the Proof of Concept for Office Automation with Open-Source Software (PoC BOSS) — preceded the program, involving 172 testers across multiple federal departments.

The study found that browser-based open-source tools were 'fundamentally suitable' for core standard processes including document editing, file storage, collaboration, and email/calendar functions. It also confirmed the solution could serve as an emergency backup if Microsoft 365 became unavailable. However, limitations were identified, particularly around large-scale video conferencing.

The Chancellery acknowledged that a full rollout would require substantial further investment in customisation, security validation, infrastructure, and staff training — and noted that numerous federal applications are deeply integrated with Microsoft's architecture, making a complete replacement a long-term proposition.

Switzerland has declared digital sovereignty a priority theme of its 2026 Digital Switzerland strategy. The program follows a broader European trend of governments investigating alternatives to US-based cloud and productivity platforms, with Germany's Schleswig-Holstein state — which has already migrated largely to open-source office tools — cited as a direct reference point.
