Tixeo vs Microsoft Teams

Why Switch from Microsoft Teams to Tixeo?

Microsoft Teams is the default European business video conferencing tool, deeply integrated with Microsoft 365. The structural problem: Teams is a US-domiciled service. Even with EU Data Boundary configurations, the corporate jurisdiction sits in Redmond, Washington — and the 2025 ICC / Microsoft incident demonstrated that US executive branch decisions can interrupt service to European institutions.

Tixeo is the French structurally sovereign alternative. ANSSI-certified (CSPN Security Visa, since 2017), end-to-end encrypted by default, used by defence companies and regulated industries. Not a Teams clone — a structurally different product for European organisations where sovereignty actually matters.

Feature Comparison

Feature	Tixeo	Microsoft Teams
Jurisdiction	France 🇫🇷	United States 🇺🇸
End-to-end encryption	✅ Default	⚠️ Optional, limited rollout
ANSSI certification	✅ CSPN Security Visa (since 2017)	❌
GDPR	✅ Native + CNIL recognised	⚠️ EU Data Boundary on some tiers
CLOUD Act exposure	❌ None	⚠️ Yes
Deployment: cloud	✅ FR	✅ US/EU
Deployment: private cloud	✅	⚠️ Limited
Deployment: on-premise	✅	⚠️ Limited (Teams Rooms ≠ on-prem)
Real-time document co-edit	Limited	✅ Best-in-class
Outlook integration	✅ Meeting-level	✅ Deep
Public chat / threads	Limited	✅
Maximum participants	250+	1,000+

These are fundamentally different products. Teams is a collaboration ecosystem. Tixeo is a sovereign video conferencing tool. The right answer depends on what you optimise for.

Pricing

Tixeo pricing scales with deployment mode:

• Tixeo Cloud, Private Cloud and On-Premise: quote-based — Tixeo publishes no list prices (as of October 2026); a free trial is available
• Tixeo On-Premise: custom licensing for dedicated infrastructure

Microsoft Teams pricing:

• Bundled with Microsoft 365: $4.50-$22/user/month depending on tier
• Standalone Teams: not commonly sold

For organisations that need only sovereign video conferencing (not the full Microsoft 365 ecosystem), request a Tixeo quote and compare it with the Teams-related part of your Microsoft 365 licensing — the sovereignty difference is substantial.

Privacy & Data Sovereignty

Tixeo’s structural advantages:

• French corporate jurisdiction — Tixeo SA is headquartered in Montpellier, France
• ANSSI Security Visa (CSPN certification) — the first video conferencing solution certified and qualified by ANSSI (2017)
• End-to-end encryption by default; Tixeo cannot decrypt your meetings
• On-premise option — for the highest sovereignty needs, deploy in your own datacentre
• No backdoors — independently evaluated as part of ANSSI qualification

For European governments, defence contractors, regulated industries, and any organisation handling sensitive non-public information, this is materially different from Teams.

Migration Guide

Migrating an organisation from Teams to Tixeo is more involved than typical SaaS migrations because Teams is deeply ecosystem-integrated. Plan for 4-8 weeks for a 100-person organisation:

1. Pilot phase with one team (2 weeks): identify integration gaps
2. Provision Tixeo Cloud account and configure SSO (1 week)
3. Integrate calendar (Outlook / Google) for meeting scheduling (3-5 days)
4. Train users on the Tixeo client (1 hour per team session)
5. Phased rollout — internal meetings first, then external (4 weeks)
6. Retain Teams for specific Microsoft 365-deep workflows; migrate external meetings to Tixeo (operational)
7. Document escalation path for sovereignty-sensitive meetings (procedural)

Estimated total time: 4-8 weeks for organisations with mixed workloads. Difficulty: Moderate-high; the primary challenge is workflow change management, not technical setup.

Example Scenarios

Illustrative scenarios of how teams typically use these tools — not documented customer case studies.

A French regional government uses Tixeo On-Premise for all sensitive intergovernmental communications. The on-premise deployment guarantees zero data leaves the prefecture network. ANSSI qualification was the procurement gate.

An EU institution uses Tixeo Cloud for sovereign-grade meetings with member-state representatives. Microsoft Teams remains in use for routine administrative meetings. The two tools coexist with clear classification of which is used for what.

A French defence contractor uses Tixeo for all customer-facing meetings involving sensitive subject matter. The combination of E2E encryption, French jurisdiction, and ANSSI qualification is required by their MOD contracts.

Company Background

Tixeo was founded in 2004 in Montpellier, France, by Renaud Ghia, Denis Angiella and Sébastien Jeanjean, building on a collaborative 3D workspace project Renaud Ghia started at EPSI Montpellier in 1999. The company moved into secure video conferencing for sovereignty-sensitive European customers, added multipoint end-to-end encryption in 2015 and received its ANSSI certification in 2017. The product continues to be developed in France.

As of 2026, Tixeo serves organisations in defence and aerospace, industry and energy, banking and finance, legal services and public administration, and has subsidiaries in Madrid (2018) and Berlin (2022).

Security & Compliance

• ANSSI Security Visa — CSPN certification of TixeoServer since 2017
• End-to-end encryption by default using ANSSI-evaluated cryptographic implementation
• ISO/IEC 27001 certified
• GDPR + French CNIL alignment
• DORA-aligned for financial-services use cases
• NIS2-aligned for essential entities
• On-premise option for maximum data control

Integration Ecosystem

• Calendar integration: Outlook, Google Calendar
• SSO: SAML 2.0, OAuth 2.0
• Mobile apps: iOS, Android
• Desktop clients: Windows, macOS, Linux
• Webhook integration for custom workflows
• API for organisation-management automation

Who Should Switch?

Tixeo is ideal for:

• EU government and public-sector organisations
• Defence contractors and regulated industries with classified or restricted communications
• Healthcare, finance, legal dealing with sensitive client information
• Any European organisation for whom the ICC / Microsoft sovereignty lesson is operationally relevant

The Bottom Line

Microsoft Teams remains the right choice for organisations that live in the Microsoft 365 ecosystem and treat sovereignty as a low-priority concern. For European organisations where sovereignty in video conferencing is real — government, defence, regulated industries, professional services with sensitive client work — Tixeo is the structurally correct choice. Its ANSSI certification is not marketing fluff: it is an independent security evaluation by France’s national cybersecurity agency.

Frequently Asked Questions

What does Tixeo's ANSSI certification mean?

ANSSI (France's national cybersecurity agency) awards Security Visas to products that pass its evaluation schemes. Tixeo's Security Visa is based on the CSPN (Certification de Sécurité de Premier Niveau, first-level security certification) of TixeoServer, with the qualification decision issued in April 2017. Tixeo describes itself as the first secure video conferencing solution to be certified and qualified by ANSSI. It is a product security certification, not a clearance for classified information.

How does Tixeo's encryption work?

Tixeo implements end-to-end encryption for all meeting traffic — the encryption operates from participant device to participant device, with the Tixeo server unable to decrypt content. This is technically distinct from 'encrypted in transit' that Teams provides, where Microsoft can decrypt content on its servers if required by US law.

Is Tixeo really used by governments?

Tixeo publicly names customers such as Airbus, BNP Paribas, Conforama and KNDS (formerly Nexter), signed its first defence-sector client in 2006, and states that 30% of the largest European defence companies use its secure video conferencing (2023). Its TixeoPrivateCloud offer runs on SecNumCloud-qualified hosting. For specific public-sector references, ask Tixeo directly.

What are the deployment options?

Three: (1) Tixeo Cloud — Tixeo hosts in French data centres. (2) Tixeo Private Cloud — Tixeo operates a dedicated infrastructure for you. (3) Tixeo On-Premise — install on your own infrastructure (typical for defense, intelligence, and high-classification customers). All three options use the same cryptographic stack.

Can I integrate Tixeo with Microsoft 365?

Yes. Tixeo offers Outlook and calendar integration for scheduling. However, the integration is meeting-link-level, not deep workflow integration like Teams-SharePoint. For organisations wanting full ecosystem integration, the trade-off is real and intentional — Tixeo prioritises sovereignty over ecosystem reach.
