AWS CloudHSM vs Clevis: 2026 Comparison
AWS CloudHSM is a free key management tool. Clevis is a free key management tool. Compare features, ratings, integrations, and community reviews side by side to find the best key management fit for your security stack.
CST VerdictBased on our analysis of available product data, here is our conclusion:
Organizations with strict key custody requirements or regulated workloads (financial services, healthcare) should use AWS CloudHSM for the single-tenant HSM model, which keeps your keys physically isolated from AWS infrastructure and other tenants. FIPS 140-2 Level 3 certification and no AWS key escrow mean you retain exclusive control, addressing the core NIST Govern requirement that often fails with shared key management services. Skip this if you need integration with AWS native services like KMS or SecretsManager without custom translation layers; CloudHSM requires explicit key provisioning and won't transparently encrypt your RDS or S3.
Infrastructure teams automating decryption workflows in CI/CD pipelines or boot sequences should use Clevis for its plugin architecture, which handles LUKS volumes and encrypted data without requiring manual key entry at deployment time. The tool's 1,159 GitHub stars and active maintenance signal real production adoption, particularly in Red Hat environments where it's deeply integrated. Skip Clevis if you need centralized key lifecycle management or auditing; it's a decryption orchestrator, not a key management platform, and assumes your keys are already provisioned elsewhere.
