CST Verdict

Based on our analysis of core features, integrations, here is our conclusion:

AWS CloudHSM

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.
