AWS Vault vs AWS CloudHSM: 2026 Comparison
AWS Vault is a free key management tool. AWS CloudHSM 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:
Developers and security teams managing multiple AWS accounts locally should reach for AWS Vault first; it's the only free tool that keeps IAM credentials out of plaintext config files by leveraging your OS keystore, eliminating the most common path to credential exposure in development environments. With 8,960 GitHub stars and active maintenance, it's proven reliable enough that most AWS-native shops have already standardized on it. Skip this if your team doesn't use local development workflows or needs centralized credential rotation and audit logging; AWS Vault is a developer tool, not a secrets manager for applications in production.
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.
