Eviden, the Atos Group brand specializing in cybersecurity products, mission-critical systems, and vision AI, has become a launch partner for the AWS European Sovereign Cloud. Its Eviden Key Management Service (KMS), featuring external key management (EKM) with a European sovereign Hardware Security Module (HSM), is now available on this new independent cloud region, providing customers with enhanced data sovereignty and compliance for highly restricted workloads.
The AWS European Sovereign Cloud addresses the increasing demand from European organizations for cloud infrastructure that aligns with EU regulatory frameworks, including data residency, operational independence, and protection against extraterritorial access. By launching Eviden KMS on this cloud, Eviden enables customers to manage encryption keys externally—using a sovereign HSM—while leveraging AWS’s enterprise-grade capabilities.
This combination ensures that even the most sensitive workloads can run with full compliance, maintaining control over cryptographic keys and minimizing exposure risks. The solution supports organizations in sectors with stringent requirements, such as government, finance, healthcare, and critical infrastructure, accelerating secure digital transformation without sacrificing performance or innovation.
Yann Vincent, Global Head of Cybersecurity Product at Eviden, Atos Group, said: “At Eviden, we are proud to play a key role in strengthening European digital sovereignty. We help organizations across Europe access the highest levels of trust, autonomy, and control over their data. This reflects our commitment to providing end-to-end sovereign solutions and reinforces Eviden’s position as a leading European player in security and innovation.”
Eviden KMS on the AWS European Sovereign Cloud provides customers with a trusted, end-to-end encryption key lifecycle management solution. The external key management approach—rooted in a European sovereign HSM—ensures that master keys remain under customer control outside the cloud environment, offering an additional safeguard beyond AWS-native protections.
Customers can begin planning migrations and deployments today, benefiting from operational autonomy, EU-based data residency, and seamless integration with AWS services. This launch marks a significant advancement in providing sovereign cloud options that meet both technical excellence and regulatory demands.
