Switzerland ditches Microsoft for open source software by 2027
For decades, Microsoft’s services have become the default operating system for countless government agencies and state organizations globally. While this ubiquity offers convenience, it has also created a situation where these entities are locked into a single ecosystem, often dictated by Microsoft’s pricing structure. This dependence is prompting a significant shift across Europe, where a growing movement is focusing on digital sovereignty by migrating toward open-source alternatives.
The question is not just about cost savings; it’s about autonomy. When state actors control their core digital infrastructure, they gain greater control over their data, systems, and future direction. This push for independence is accelerating across the continent, with nations like France actively moving away from Windows in favor of Linux to reduce dependencies on non-European entities.
Switzerland is taking a concrete step toward this goal. The Federal Chancellery recently initiated a proof-of-concept study to determine if its Federal Administration could successfully operate using open-source software instead of the widely adopted Microsoft 365 suite. The results proved that the shift is fundamentally feasible.
The comprehensive study tested the full spectrum of core workplace functions, including document editing, email, calendar, file storage, project management, knowledge management, and communication tools like chat and video conferencing. The finding was clear: while there remain organizational and technical hurdles preventing widespread immediate adoption, the tested browser-based open-source solution is perfectly suitable for managing core standard processes.
To demonstrate this potential, the investigation compared Microsoft’s stack against a robust suite of open-source tools. These alternatives included Collabora Online for editing, Open-Xchange for email and scheduling, Next Cloud for file storage, OpenProject for project management, XWiki for knowledge management, and Nordest (Jitsi) for conferencing and chat. This variety of tools showcases that a cohesive, functional system can be built entirely outside the Microsoft framework.
With the technical feasibility established, the next step is implementation. The Swiss government plans to launch a follow-up program to trial this open-source integration for thousands of employees. The long-term vision, backed by the Swiss Federal Council, aims to enable approximately 3,000 employees to utilize sovereign workplace software for core office functions by the end of 2027, funded through initiatives aimed at developing a sovereign Swiss open-source platform.
This effort is part of a broader European trend. The movement to embrace open source is not just a technical choice; it is an economic and political declaration. By prioritizing open source, governments are not only striving for cost efficiency but are actively exercising their right to digital sovereignty, building resilient, self-determined digital futures across the continent.
