What France is actually committing to
France has been steadily accelerating its digital sovereignty strategy, driven in part by the changed relationship with the United States under the Trump administration. The latest move, announced on 8 April 2026, is the most comprehensive digital sovereignty measure the French state has yet announced. DINUM, the Interministerial Digital Directorate, has ordered every government ministry to formalize a plan to eliminate extra-European digital dependencies by autumn 2026. The directive covers operating systems, collaborative tools, cloud infrastructure, and artificial intelligence platforms.
The Directive: A Nationwide Migration from Windows to Linux
DINUM itself will migrate its workstations from Windows to Linux, setting a precedent for the rest of the government ministries. The plans are required to address eight categories of dependency, including workstations and operating systems, collaborative and communication tools, antivirus and security software, artificial intelligence and algorithms, databases and storage, virtualization and cloud infrastructure, and network and telecommunications equipment. No specific Linux distribution has been named in the public announcement, and individual ministries retain the flexibility to choose their migration path within that framework.
La Suite Numérique: A Stack of Sovereign Productivity Tools
The software replacement strategy for the most common desktop tasks is already in place in the form of La Suite Numérique, a stack of sovereign productivity tools developed and maintained by DINUM. It includes Tchap, an end-to-end encrypted messaging application already deployed to more than 600,000 civil servants, Visio for video conferencing, a sovereign webmail service, file storage, and collaborative document editing. The entire platform is hosted on Outscale servers, a subsidiary of Dassault Systèmes, and is certified SecNumCloud by the French information security agency ANSSI.
A Precedent for Success: The Gendarmerie Nationale
Announcements of government Linux migrations have a long and largely disappointing history. However, France has a reason to believe this time is different, and the reason is the Gendarmerie nationale. Beginning in 2004 with a phased adoption of OpenOffice, Firefox, and Thunderbird, the Gendarmerie progressively built the internal competencies and governance structures required for a full operating system switch. In 2008 it launched GendBuntu, its customised Ubuntu-based deployment. By June 2024, GendBuntu ran on 103,164 workstations, representing 97% of the force’s computing estate. The financial outcome has been unambiguous: the project saves approximately two million euros per year in licensing costs and has reduced the total cost of ownership by an estimated 40%.
The International Context Adds Further Validation
Germany’s state of Schleswig-Holstein, which began its own Microsoft-to-Linux transition in earnest in 2024, completed nearly 80% of its 30,000-workstation migration by early 2026 and recorded savings of €15 million in licensing costs in 2026 alone. The lesson both cases illustrate is the same: phased migration with coherent governance, strong internal competencies, and a well-defined strategy can lead to significant cost savings and improved digital sovereignty.
The Next Milestone: Industrial Digital Meetings
The next milestone is a first set of “Industrial Digital Meetings” scheduled for June 2026, where DINUM intends to formalise public-private coalitions to support the transition. These meetings will bring together stakeholders from industry, government, and academia to discuss the challenges and opportunities of the migration, and to identify potential solutions and best practices.
A Digital Sovereignty Strategy
France’s digital sovereignty strategy is not just about migrating to Linux, but about creating a more autonomous and resilient digital ecosystem. The country is accelerating its push for cloud sovereignty, driven in part by the changed relationship with the United States under the Trump administration. The latest move is part of a broader effort to reduce dependence on American vendors and to promote European cloud sovereignty.
Conclusion
France’s decision to migrate from Windows to Linux is a significant step towards digital sovereignty. The country has a precedent for success in the Gendarmerie nationale, which has demonstrated that phased migration with coherent governance and strong internal competencies can lead to significant cost savings and improved digital sovereignty. The international context adds further validation, with Germany’s state of Schleswig-Holstein having completed a similar migration with impressive results. The next milestone is the Industrial Digital Meetings, which will bring together stakeholders to discuss the challenges and opportunities of the migration. France’s digital sovereignty strategy is not just about migrating to Linux, but about creating a more autonomous and resilient digital ecosystem. The country is accelerating its push for cloud sovereignty, driven in part by the changed relationship with the United States under the Trump administration. The latest move is part of a broader effort to reduce dependence on American vendors and to promote European cloud sovereignty.
