Paris, France – October 6, 2025 – Eviden, the Atos Group product brand leading in advanced computing, cybersecurity products, mission-critical systems and vision AI today announces the strengthening of its cybersecurity product offering through the integration of Cosmian’s Key Management System (KMS1).
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. The merger between Cosmian and Eviden enhances France’s sovereign know-how in cryptography. Cosmian’s industry-leading cryptographic expertise supports Eviden’s capabilities in advanced encryption, including hardware (HSM2), confidential computing3 and encryption key management. Together, the two French players offer organizations concerned with sovereignty issues a unique know-how, particularly in scalable application data encryption and optimal interoperability with customers’ information systems.
Thanks to this integration, Eviden offers as of now innovative and high-performance key management using advanced encryption algorithms, including post-quantum encryption (PQC4), which can be deployed in all types of IT architectures – from on-premise, to public or hybrid cloud – with the operational flexibility and adaptability expected by customers for a more efficient end-to-end data security and privacy.
Pierre-Yves Jolivet, Executive Vice President, Head of Eviden and Cybersecurity, Atos Group, said: “Our European cybersecurity product offering, enhanced with advanced key management features, ensures the highest level of data confidentiality, integrity and confidentiality, throughout its lifecycle, in line with our commitment to sovereign cybersecurity that integrates 100% European solutions. »
