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 secrets rotation without a separate vendor will find AWS Secrets Manager operationally simpler than standalone KMS tools, since it handles both storage and automated rotation in one service. The free tier covers most non-enterprise use cases, and native IAM integration means no separate identity layer to manage. Skip this if you need hardware security modules or are locked into a non-AWS environment; Secrets Manager prioritizes convenience over portability, and its rotation logic is AWS-specific enough that migrations are painful.
Enterprise teams managing secrets across IBM Cloud infrastructure will value IBM Cloud Secrets Manager for its single-tenant isolation model, which eliminates the blast radius risk of shared multi-tenant vaults. The HSM-backed PKI and dedicated instance architecture directly address NIST PR.AA access control requirements without forcing secrets into a shared environment. Skip this if you need a vendor-agnostic secrets engine; IBM Cloud Secrets Manager assumes you're already committed to IBM's ecosystem and integrates tightly with their toolchains and Key Protect service rather than standing alone.
