Atos: Eviden Deploys Its Sovereign Encryption Solution on the European AWS Cloud

Introduction of Eviden KMS on AWS European Sovereign Cloud

Eviden now offers Eviden KMS on the AWS European Sovereign Cloud, an independent cloud service operated with enhanced technical controls and sovereign guarantees aimed at European governments and businesses. The solution is based on a European sovereign hardware security module (HSM) acting as a root of trust, with the master key kept off the cloud. This architecture allows for sovereign management of the encryption key lifecycle from the design phase, while maintaining the security, availability, and performance expected. The immediate availability of Eviden KMS on this independent cloud targets organizations facing complex regulatory requirements needing operational autonomy and data localization within the European Union.

Meeting Strict Sovereignty and Compliance Needs

Eviden's solution meets the needs of clients whose sovereignty and compliance requirements are among the strictest, particularly in demanding regulatory sectors. By combining its European external key management with AWS's technical controls and guarantees, Eviden aims to support compliance and innovation challenges, facilitating the digital transformation acceleration of these organizations. Eviden KMS will be showcased at the AWS Summit in Paris on April 1, 2026, and at the INCYBER Forum Europe from March 31 to April 2, 2026.
