Eviden, the Atos Group product brand, pioneering in advanced computing, cybersecurity products, mission-critical systems, and vision AI announces the strengthening of its cybersecurity product offering through the integration of Cosmian’s Key Management System (KMS).

In an era marked by rapidly increasing cyber threats, it is imperative that French and European companies retain control over the security of their most sensitive data, irrespective of deployment environment.
