CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Mid-market and enterprise teams with sensitive data spread across endpoints, mobile, and cloud need encryption that doesn't require a security team to manage keys; Armor DataArmor puts cryptographic control directly in the hands of individual users through organization-owned key management and location-aware protection. FIPS 140-2 compliance and unique per-file encryption keys address PR.DS requirements without the operational overhead of centralized key rotation. This is not for buyers looking for a detection-first security posture; Armor DataArmor prioritizes data confidentiality at rest and in transit, leaving visibility and threat response to other tools in your stack.
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.
