Features, pricing, ratings, and pros & cons — compared head-to-head.
IBM Cloud Secrets Manager is a commercial key management tool by IBM. Key Vault 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 NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
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.
Teams already committed to Azure will find Key Vault's native integration and zero cost the obvious choice for secrets management at scale. It meets FIPS 140-2 Level 2 certification and integrates directly with Azure's identity layer, eliminating the friction of third-party credential sync. Skip this if your infrastructure spans multiple clouds and you need a vendor-agnostic secrets engine; Key Vault's Azure-first design means non-Azure workloads end up as second-class citizens in your rotation workflows.
