On January 26, 2026, France declared war on US collaboration tools. Minister Delegate David Amiel announced the complete replacement of Zoom and Microsoft Teams across all government services, ordering 200,000 workers to migrate to “Visio”—a domestically-developed, open-source platform—by 2027. Amiel’s blunt justification: France needs to “detoxify” from American technology. The first test arrives in 8 weeks: France’s National Center for Scientific Research (CNRS) will terminate all Zoom contracts by March 2026, forcing 154,000 users onto Visio.
This isn’t another vague digital sovereignty initiative. France is mandating infrastructure replacement with hard deadlines. Moreover, Germany’s already replacing Microsoft for 30,000 civil servants. Austria’s deploying Nextcloud. If France’s rollout succeeds, expect EU-wide government bans on Zoom and Teams.
The 8-Week Countdown: CNRS’s Forced March Off Zoom
CNRS didn’t get a choice. The organization terminated its Zoom contract, triggering a hard March 2026 deadline for 154,000 users. That’s 8 weeks from announcement to completion—aggressive by enterprise IT standards, which typically allow 6-12 months for migrations of this scale.
Other agencies are deploying in Q1 2026. Health Insurance is switching to protect patient data. Finance Ministry is migrating to keep tax information off US servers. Furthermore, the Armed Forces are moving classified communications to French infrastructure supervised by ANSSI, France’s cybersecurity agency.
What Is Visio: Open-Source, SecNumCloud-Certified, ANSSI-Supervised
Visio is built on open-source technologies (likely Jitsi or similar WebRTC platforms), hosted exclusively on French infrastructure certified by ANSSI’s SecNumCloud standard. All data stays in France. No traffic crosses borders. No third-party access without government permission.
SecNumCloud certification requires meeting 350+ security requirements. Version 3.2 includes protections against extraterritorial laws—the US CLOUD Act can’t touch SecNumCloud data. Visio runs on Outscale, a Dassault Systèmes subsidiary, giving France complete control from hardware to application.
Summer 2026 brings AI-powered real-time subtitling through Kyutai, a French AI research lab. Unlike OpenAI Whisper (which Zoom uses), Kyutai’s models are developed in France and don’t send audio to US cloud providers.
Why “Detoxify from US Tech”? Data Sovereignty Meets Geopolitics
Amiel’s “detoxify” language is deliberate. France has three concrete concerns.
First, data sovereignty. The US CLOUD Act allows American law enforcement to access data stored by US companies, even if physically hosted in Europe. French government communications on Zoom or Teams are accessible to US authorities. Consequently, SecNumCloud hosting removes this vulnerability.
Second, cybersecurity. ANSSI oversees Visio deployment directly. Microsoft and Zoom patch on their own schedules. France gets no visibility into their security practices. In contrast, with Visio’s open-source foundation, the government controls security completely.
Third, cost. Eliminating Zoom Enterprise licenses ($20-30 per user annually) and Teams subscriptions for 200,000 workers saves millions in recurring fees to US companies. France is trading license costs for infrastructure costs—but those investments stay in the French economy.
The EU Domino Effect: Germany and Austria Are Already Moving
France isn’t pioneering this alone. Germany’s Schleswig-Holstein is replacing Microsoft for 30,000 civil servants. Austria’s Ministry of Economy deployed Nextcloud for 1,200 employees, with other ministries following.
Nextcloud reports interest in sovereign alternatives has tripled since early 2025. The company is investing €250 million in digital sovereignty through 2030. If France’s mandate succeeds, Germany could mandate similar transitions federally. Consequently, the EU Commission could create unified frameworks for sovereign collaboration tools, effectively ending Microsoft and Zoom’s government contracts across the bloc.
The Feature Parity Question: Can Visio Actually Replace Zoom?
Here’s the uncomfortable reality: Zoom and Teams have 10+ years of enterprise development. Breakout rooms, webinars, virtual backgrounds, third-party integrations—these weren’t built overnight. Visio launched its pilot a year ago. The feature gap exists.
International collaboration poses practical problems. What happens when French officials need to meet with US or non-EU partners using Zoom? If Visio doesn’t support federation, French workers may need dual accounts or force partners to create Visio accounts. NATO meetings and international research partnerships all require cross-border conferencing. Therefore, France is betting data sovereignty justifies this friction.
Migration pain is underestimated. CNRS’s 8-week timeline for 154,000 users is aggressive. First-week help desk tickets will be brutal. France needs CNRS’s Q1 2026 migration to succeed smoothly, or the entire 2027 rollout becomes vulnerable.
What’s Next: The 2026 Test Cases
March 2026 is the proof-of-concept deadline. If CNRS successfully migrates without major disruptions, Visio’s credibility is established. Other EU governments will take notice. However, if CNRS’s migration struggles—poor user experience, failed international meetings—France’s digital sovereignty initiative takes a major hit.
For developers and tech professionals, this signals the future of B2B SaaS in Europe. Government contracts are shifting toward open-source, locally-hosted, sovereignty-compliant tools. If your product relies on European government customers, start planning for SecNumCloud certification and EU data residency.
