Engage Black BlackVault HSMs vs ProvenRun ProvenHSM: Side-by-Side Comparison (2026)

Engage Black BlackVault HSMs

Mid-market and enterprise teams that need hardware-backed key generation and storage will find the Engage Black BlackVault HSMs valuable for satisfying FIPS 140-2 Level 3 requirements without cloud dependencies. The tamper-reactive silicon die shield and on-device cryptographic operations directly address NIST PR.DS and PR.AA controls that auditors actually scrutinize. Skip this if your organization has standardized on cloud-native key management or needs integration breadth beyond certificate authorities and legacy CAPI/CNG environments; the four-person vendor and narrow API support mean you're betting on stability over ecosystem expansion.

ProvenRun ProvenHSM

Enterprise and mid-market security teams handling high-volume cryptographic operations or managing qualified electronic signatures should pick ProvenRun ProvenHSM for its formally verified OS, the only HSM platform with CC EAL7 assurance underneath the key management layer. It hits FIPS 140-3 Level 3, sustains 10,000 ECDSA signatures per second, and ships post-quantum cryptography algorithms ready for 2030+ compliance, which matters if your PKI roadmap extends beyond RSA. Skip this if you need plug-and-play integration with legacy enterprise tools; ProvenHSM demands custom development work and technical depth from your team, and the 56-person vendor means you're betting on a smaller player than Thales or Fortanix for long-term support.
