Digital technology is no longer neutral
In an increasingly tense digital world where sovereignty has become a strategic necessity, choosing a collaborative platform is far from trivial.
Should we continue relying on tools subject to the US Cloud Act, or move towards secure French solutions that comply with the strictest cybersecurity standards?
In this clash of titans, Microsoft Teams stands out for its popularity… but Whaller, a French platform certified SecNumCloud, offers a trustworthy alternative for French administrations and enterprises.
Here’s a clear, no-nonsense comparison.
Security and sovereignty: Whaller, the obvious choice
Security is not optional for strategic institutions. Whaller is today the first collaborative platform to obtain SecNumCloud qualification from the ANSSI, making it the preferred choice for public entities, OIVs, and sensitive organisations.
By contrast, Microsoft Teams, while effective, is hosted under US jurisdiction and therefore subject to the Cloud Act — a law allowing US authorities to access data stored abroad.
👉 In practice: The French Army has chosen Whaller for its “Army Families” collaborative space, underlining the growing importance of digital sovereignty in the military sector (read the interview).
Features: Two complete ecosystems, different philosophies
Microsoft Teams impresses with its integrated Office suite and meeting tools, but can quickly become heavy and complex for French organisations that don’t need such a closed ecosystem.
Whaller, on the other hand, offers all the key features expected from a modern collaborative suite:
- Isolated spheres for secure team organisation,
- Document co-editing, task management, and polls,
- Video conferencing and webinars without external dependency,
- Widgets to enrich spaces according to user needs.
Above all, it offers fine-grained modularity tailored to real-world French use cases.
For instance, MyKiwi chose Whaller to support its clients’ digital transformation, praising the platform’s flexibility and ease of adaptation to business workflows (read the testimonial).
Customisation: Whaller adapts to your identity
User experience matters. On Whaller, each sphere can be customised:
- Logo,
- Colours,
- Dedicated widgets,
- Full branding to strengthen belonging and identity.
In contrast, Teams remains more rigid: a single visual identity for all users, dictated by Microsoft.
👉 In practice: Universities and schools (such as Saint-Christophe and Sainte-Adèle) use Whaller’s customisation features to create learning spaces in their own image, boosting engagement among students and teachers (read the interview).
Cost and transparency: Whaller, accessible with no hidden fees
On the financial side, Whaller also stands out:
- A comprehensive free version to get started,
- Pro plan at €3/month per user, with no hidden costs,
- Hosting in France, with no data transfers outside the EU.
By contrast, Teams usually requires a full Microsoft 365 subscription, often exceeding actual user needs, and additional fees for advanced security.
👉 In practice: OVHcloud uses Whaller to energise its internal communications, taking advantage of a sovereign, efficient, and cost-controlled solution (read the testimonial).
Conclusion: Sovereignty, flexibility, simplicity – Whaller ticks all the boxes
For organisations seeking to regain control of their digital tools without compromising performance, Whaller stands as a credible, reliable, and sovereign alternative to Microsoft Teams.
Its SecNumCloud qualification, flexibility, customisation capabilities, and transparent pricing make it a strategic choice for any French administration or business with high security expectations.
