Azure Managed HSM vs Eviden KMS

Azure Managed HSM is a cloud service for managing cryptographic keys backed by hardware security modules. It supports customer-managed keys, automatic key rotation, audit logs and key import through a web-accessed service. Both listed key types are supported. The Standard B1 plan is a Managed HSM pool billed by hourly usage fee per HSM pool; no price is provided. Azure lists no free plan. The cloud deployment model suits organisations that want managed HSM capabilities rather than a self-hosted installation. Key import allows existing keys to be brought into the service, while automatic rotation handles scheduled key changes. Audit logs provide activity records for review. Teams evaluating the service can focus on whether HSM-backed protection, customer control, import, rotation and logging meet their key-management needs, and whether hourly pool billing fits their usage.

Eviden KMS centralizes encryption and decryption, key management, and certificate management. Its architecture combines key lifecycle management, an encryption oracle, and public key infrastructure. Administrators can generate, store, rotate, distribute, and revoke keys, and set access policies. The product supports FIPS 140-3 mode and KMIP versions 1.0–1.4 and 2.0–2.1 in binary and JSON formats, but implements a targeted subset rather than the entire KMIP standard. Listed integrations include Trustway Proteccio, Crypt2Pay, Utimaco, Nitrokey HSM 2, and SmartCard HSMs; cloud options include Azure BYOK, GCP CSEK and CMEK, AWS BYOK, and AWS Fargate. It also integrates with Google Workspace Client-Side Encryption, Microsoft 365 Double Key Encryption, and several databases. Deployment options include Debian and RPM packages, Windows and macOS installers, and standard or FIPS Docker images. Its web GUI supports client certificates and OIDC token authentication. Pricing is on request, with per-CPU pricing, connectors included, and any number of servers.
