CST Verdict

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

Key Vault

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.
