Eviden KMS vs KeyRack

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.

KeyRack is an open-source key management coordination layer that you deploy in your own infrastructure, rather than use as a hosted cloud KMS. It tracks key hierarchies, drives rotation and delegates cryptographic operations to configured backends. Its KEK-wrapping hierarchies support namespace-scoped rules and cascade operations. Authorization is checked on every operation through an external policy decision point such as Cedar or OPA; KeyRack does not bundle an identity provider, but can integrate with OIDC providers including Keycloak, Auth0, Okta, Azure AD and Google Identity Platform. Backend choices include PKCS#11, HashiCorp Vault Transit, a KMIP client and in-process software for development and testing. Audit events can be delivered through NATS, files or stdout, with BLAKE3 hash-chain linking and optional Ed25519 signing. Non-exportable keys in an HSM or Vault provider remain there; exportable keys may leave through authorized export operations. The open-source core costs nothing under AGPL-3.0-or-later. Commercial licensing is available by contacting KeyRack for pricing and evaluation access.
