CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
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.
Mid-market and enterprise product teams embedding key management into their own platforms will get the most from Cryptsoft KMIP SDKs; the OASIS KMIP standard compliance eliminates vendor lock-in and lets you ship standards-based key handling without rebuilding it from scratch. The 30+ integrations across storage, databases, and security vendors validate that the SDKs actually work in production environments, not just labs. Skip this if you're looking for a turnkey key management service rather than SDK components to build with; Cryptsoft is for vendors and large organizations that need to ship KMIP-capable products, not for teams that want to outsource key management entirely.
