Microsoft Teams and France’s Sovereign Video Conferencing Initiative: A Closer Gaze at Jitsi-Based Solutions

As governments and enterprises worldwide reassess their digital infrastructure for security and data sovereignty, France has emerged as a leader in promoting open-source alternatives to proprietary collaboration platforms. Central to this effort is the adoption of Visio, a sovereign video conferencing platform built on the open-source Jitsi framework, which is being positioned as a secure, privacy-respecting alternative to tools like Microsoft Teams. This initiative reflects a broader European push to reduce reliance on non-EU technology providers, particularly in sensitive sectors such as defense, healthcare, and public administration.

The Rise of Sovereign Cloud and Communications in Europe

Concerns over data privacy, foreign surveillance laws (such as the U.S. CLOUD Act), and vendor lock-in have driven several European nations to explore domestically controlled digital solutions. France’s Etalab, the government’s task force for open data and open source, has been instrumental in advancing the use of open-source software across public services. The Visio platform, developed under Etalab’s guidance, is one of the flagship outcomes of this strategy.

Unlike Microsoft Teams, which stores user data on servers potentially subject to extraterritorial legal requests, Visio is designed to be self-hosted, allowing French public institutions to retain full control over their data. Built on Jitsi — an open-source project originally created by Atlassian and now maintained by the community under 8×8 — Visio offers end-to-end encryption, screen sharing, recording, and integration with existing identity systems like ANSSI-certified directories.

How Jitsi Powers Secure, Customizable Video Conferencing

Jitsi Meet, the core component of the Visio platform, is a fully open-source WebRTC-based video conferencing solution. It requires no user accounts or plugins and can be deployed on private servers, giving organizations complete oversight of infrastructure and data flows. Key features include:

• End-to-End Encryption (E2EE): Optional E2EE ensures that only meeting participants can decrypt audio and video streams.
• No Central Data Storage: When self-hosted, no metadata or call data is sent to third parties.
• Customization and Integration: Organizations can modify the interface, add branding, or integrate with LDAP, SAML, or OAuth systems.
• Scalability: With proper server architecture, Jitsi can support thousands of concurrent users.

These attributes produce Jitsi particularly appealing for government use cases where compliance with GDPR and national security regulations is mandatory.

France’s Visio: A Model for Digital Sovereignty

Launched in 2020 as part of France’s Plan pour une Souveraineté Numérique (Plan for Digital Sovereignty), Visio has been adopted by numerous ministries, local governments, and public hospitals. The platform is hosted on infrastructure certified by ANSSI, France’s national cybersecurity agency, ensuring compliance with the country’s strict SecNumCloud security standards.

According to a 2023 report by Next INpact, over 1,200 French public institutions were using Visio or similar Jitsi-based solutions, representing hundreds of thousands of monthly active users. The French Ministry of Armed Forces, for example, has mandated the use of sovereign communication tools for classified discussions, further validating the platform’s credibility in high-security environments.

Schleswig-Holstein and the German Push for Open Source

France is not acting alone. In Germany, the northern state of Schleswig-Holstein has also embraced Jitsi-based videoconferencing as part of its Digital Sovereignty Strategy. The state government migrated thousands of employees to a self-hosted Jitsi instance in 2021, citing concerns over data privacy and long-term cost efficiency.

A spokesperson for Schleswig-Holstein’s Ministry of the Interior confirmed to Heise Online that the move reduced dependency on U.S.-based vendors while improving transparency in data handling. The state now offers its Jitsi service as a model for other German states and federal agencies considering similar transitions.

Microsoft Teams: Ubiquity vs. Control

While Microsoft Teams remains the dominant enterprise collaboration tool globally — with over 300 million monthly active users as of 2024 — its centralized architecture raises concerns for organizations prioritizing data sovereignty. Although Microsoft offers data residency options in Europe, including EU Data Boundary commitments, critics argue that ultimate control still resides with a non-European corporation subject to foreign jurisdiction.

In contrast, Visio and similar Jitsi deployments allow nations and organizations to answer a critical question: Who controls the keys to our communication infrastructure? By choosing open-source, self-hosted solutions, they ensure that the answer is: We do.

Challenges and Trade-Offs

Adopting sovereign platforms like Visio is not without challenges. Organizations must invest in:

• Technical Expertise: Deploying and maintaining Jitsi requires skilled DevOps and IT staff.
• User Training: Transitioning from familiar platforms like Teams necessitates change management.
• Feature Parity: While Jitsi excels in core video conferencing, it lacks some of the deep integrations (e.g., with Office 365, SharePoint, or Power Platform) that make Teams indispensable for many workflows.

Nonetheless, many public sector entities view these trade-offs as acceptable given the strategic importance of digital independence. As one ANSSI official stated in a 2023 interview with Le Monde Informatique, “Sovereignty isn’t just about where data is stored — it’s about who can access it, under what legal framework, and whether we can audit and modify the tools we rely on.”

The Future of Sovereign Collaboration in Europe

The success of initiatives like Visio and Schleswig-Holstein’s Jitsi deployment is inspiring similar efforts across Europe. The European Declaration on Digital Rights and Principles emphasizes the importance of open source and interoperability in public services. Meanwhile, projects such as EU Open Source Strategy and the Digital Europe Programme are funding open-source alternatives to proprietary cloud services.

Looking ahead, hybrid models may emerge — where organizations use sovereign platforms for sensitive communications while retaining tools like Teams for less critical, collaboration-heavy tasks. Interoperability standards, such as those being developed under the Matrix protocol, could eventually allow seamless communication between Jitsi-based systems and mainstream platforms without compromising security.

Key Takeaways

• France’s Visio platform, built on the open-source Jitsi framework, provides a secure, self-hosted alternative to Microsoft Teams for government and public sector use.

• Hosted on ANSSI-certified infrastructure, Visio ensures data remains under French jurisdiction, addressing GDPR and national security concerns.
• Schleswig-Holstein in Germany has adopted a similar Jitsi-based solution, reflecting a broader European trend toward digital sovereignty.
• While Jitsi lacks some of the advanced integrations of Microsoft Teams, it offers unmatched control, transparency, and customization for organizations prioritizing privacy and independence.
• The shift toward open-source collaboration tools is supported by EU policies and funding initiatives aimed at reducing reliance on non-European technology providers.
