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 teams managing sensitive data across Google Workspace or Microsoft 365 need Virtru Private Keystore if regulatory compliance requires encryption keys to stay in your own infrastructure, not the vendor's. Docker-based deployment across public cloud, private cloud, or HSM means you control key residency without architectural rework, and CJIS, HIPAA, CMMC 2.0, and ITAR support validates that claim. Skip this if your team lacks the ops capacity to run a separate key management appliance or if you need key rotation and lifecycle management at scale; Virtru prioritizes key custody over key operations.
