Collaborative work, under high security
"We needed an easy-to-use, ergonomic collaboration suite that met our security constraints and was GDPR-compliant. Talkspirit checked every box!" — Céline Massy, Deputy CIO and Digital Transformation Architect, CEA
Collaborative work, under high security

Europe's leading innovative public body
Founded in 1945, the CEA (French Alternative Energies and Atomic Energy Commission) is a public research body — Europe's leading innovative public body. Four domains: defence and security, nuclear and renewable energy, technological research for industry, and fundamental research.
20,000 employees (15,000 in the civilian branch, 5,000 in the military branch), 9 research centres across France. In 2020, the CEA rolled out Talkspirit across its civilian branch.
Collaborating without ever compromising on security
In 2020, the CEA launches a digital workplace for its 15,000 civilian employees: easing information sharing and centralising exchanges. But its activities demand highly secure solutions.
Data that can't leave
The Covid crisis forces Teams into place in a hurry — a stopgap solution, to be quickly replaced by a sovereign alternative.

A benchmark, a crisis, a sovereign choice
Why Talkspirit: French software (created in 2008 by Philippe Pinault and Olivier Ricard), hosted in France, outside the Cloud Act, already proven with public institutions (French Army, CNRS, CNES, CPAM) — and easy to use.
Slack, Teams… then Talkspirit
The CEA evaluates several tools on technical, security, and user experience criteria. The Covid crisis forces Teams into place urgently — but the Cloud Act disqualifies it for sensitive data.
A European, sovereign alternative
Digging deeper into European players, the CEA picks Talkspirit to replace Teams: security, hosting in France, GDPR compliance, ease of use.
From 30 to 5,500 users
A gradual but fast rollout: first small working groups, then IT and business units — from 30 to 300, then to several thousand. Six months after launch: 5,500 users, nearly two-thirds active every month.
Toward 15,000 users, partners included
Users have a lot of freedom (everyone creates their own groups), with close support from the Talkspirit team. The CEA has just ordered 10,000 licences and is aiming for 15,000 users, opening mixed communities with its research partners (CNRS, INSERM, INRIA).
Sovereign, easy to use, adopted
What the digital workplace changed at the CEA.
users in 6 months
From a handful of pilot groups to several thousand users — nearly two-thirds active every month.

Outside the Cloud Act, hosted in France
Where Teams and Slack opened a door to data, Talkspirit protects confidentiality: data in France, GDPR compliance, regular audits.

A new reflex
Not very accustomed to remote work before the crisis, the CEA made the platform the place where information gets shared — simplifying remote collaboration.
