Private Machines ENFORCER is a commercial key management tool by Private Machines Inc.. ProvenRun ProvenHSM is a commercial key management tool by ProvenRun. 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 and mid-market teams protecting cryptographic operations or sensitive computation in physically accessible environments should evaluate Private Machines ENFORCER for its FIPS 140-2 Level 4 certification and hardware-enforced runtime integrity; the integrated HSM per compute blade and remote attestation cover both PR.DS and PR.PS in ways software-only key management cannot match. Skip this if you need edge deployment flexibility or support for non-x86 workloads, where the compact form factor advantage evaporates and operational complexity rises sharply.
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.
