Key Developments
- Swiss government agencies are transitioning from Microsoft 365 to openDesk.
- The Swiss Federal Chancellery and the Swiss Armed Forces are implementing changes at different rates.
- The shift aims to safeguard Swiss data from external surveillance.
Switzerland’s federal government is initiating a shift towards an open-source digital workspace for thousands of its employees, while the Swiss Armed Forces’ Cyber Command is accelerating its transition away from Microsoft 365, particularly for sensitive tasks.
This movement reflects a broader trend among various European governmental bodies, including those in Austria, France, Germany, and Ireland, which are also abandoning Microsoft 365 and Windows in favor of open-source office suites and Linux.
Following a feasibility study, the Swiss Federal Chancellery determined that an open-source, browser-based office suite could effectively manage essential administrative tasks. Consequently, the government has begun deploying a platform for office and collaboration that will operate alongside Microsoft 365. By the end of 2027, the platform is expected to support approximately 3,000 of the 47,000 employees engaged in critical functions across various federal departments.
The planned platform, openDesk, is a German-developed open-source solution that encompasses email, calendars, documents, presentations, telephony, and audio and video conferencing. This initiative is not isolated to Switzerland; Germany and the International Criminal Court have also adopted openDesk.
Switzerland’s government frames this initiative as a step towards digital sovereignty and resilience during crises, rather than a straightforward replacement for Microsoft 365. The Federal Chancellery emphasized that this independent platform should serve as a viable backup for essential processes, particularly if Microsoft 365 becomes inaccessible.
The estimated initial investment for this program is around 9 million Swiss francs, funded through parliamentary allocations aimed at developing a sovereign Swiss open-source platform for office automation. The first phase focuses on platform construction and establishing a framework for assessing the costs of a potential wider implementation and ongoing operations.
The government has noted that achieving technical feasibility is merely the first step. The transition will necessitate significant customization, security measures, platform assessments, and additional internal expertise. A particular challenge lies in the number of applications and specialized systems that are heavily integrated with Microsoft’s architecture.
Currently, the Swiss government has not made the decision to overhaul its entire federal desktop environment. The choice to expand the program government-wide will be determined following the initial rollout.
Military’s Rapid Shift to Open-Source Software
Conversely, the Swiss Armed Forces’ Cyber Command, along with its Cyber and Electromagnetic Actions unit, is on a much more expedited schedule.
By October, all personnel in these units are set to transition to the open-source alternative openDesk in their workplaces. This urgency is underscored by Swiss technology journalist Adrienne Fichter, who remarked, “Anyone who still needs reasons to break free from dependence on American Big Tech companies: The US government reliably provides them.”
Fichter further elaborated that “All US tech companies are kept on a short leash by the current administration: They must hand over data at Washington’s behest and must shut down services at Trump’s command.”
The Swiss military lacks trust in American cloud providers, prompting the transition to openDesk after deeming Microsoft 365’s cloud-based model unsuitable for military standards regarding confidentiality, availability, and integrity.
As a result, the Swiss Cyber Command’s specialists are moving to openDesk “in record time.” The objective is to minimize exposure to foreign legal and technical dependencies as swiftly as possible.
Reports indicate that the military is particularly wary of data held by US tech companies being subject to access by the US government under the CLOUD Act, which allows American law enforcement to compel US-based technology companies to disclose electronic data irrespective of where that data is stored. For a military organization dealing with highly sensitive and potentially classified information, this situation is entirely unacceptable.
Efforts for European Sovereignty
OpenDesk is part of a larger European initiative aimed at providing public authorities with alternatives to cloud-based productivity suites dominated by hyperscalers. Instead of being a direct replica of Microsoft 365, openDesk integrates various open-source office, communication, collaboration, and file management components into a unified user experience.
This strategy exemplifies an emerging perspective in European public-sector IT: open-source solutions are increasingly viewed not just as a software development model, but as a means of ensuring operational autonomy and achieving digital sovereignty.
While governments may still utilize commercial and cloud-hosted services, there is a growing demand for independently controllable options for critical operations, especially those that cannot afford to rely on external providers or foreign jurisdictions, which could lead to vulnerabilities in service availability.
The transition is not yet a sweeping declaration that Microsoft is phased out. Instead, it represents a dual-track approach: a methodical 3,000-user civilian initiative designed to evaluate a sovereign alternative alongside Microsoft 365, and a much faster military transition led by cyber specialists who consider this alternative essential for high-security operations. The trend is evident; countries across the globe, not just in the EU, are shifting away from proprietary American services towards open European alternatives.
