CST Verdict

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

AWS Key Management Service

AWS teams that need encryption keys tied directly to their infrastructure will find AWS Key Management Service indispensable; it integrates natively with 200+ AWS services and eliminates the operational burden of managing a separate HSM or third-party vault. AWS offers free tier usage and FIPS 140-2 Level 2 certification for the service itself, though the CloudHSM option reaches Level 3 if compliance demands it. Skip this if your organization runs multi-cloud or hybrid infrastructure requiring vendor-agnostic key management; AWS KMS locks you into AWS's envelope encryption model and won't federate keys across platforms.
