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 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.
Fortanix Confidential Computing
Enterprise security teams protecting sensitive computation on untrusted infrastructure need Fortanix Confidential Computing because it encrypts data while it's actively processing, not just in transit or at rest. Intel SGX and AMD SEV support across major cloud providers means you're getting hardware-backed isolation that the OS and hypervisor can't breach, directly strengthening PR.DS and PR.PS controls. Skip this if your threat model doesn't include a compromised cloud provider or if you're managing workloads that can't be refactored for enclave execution; Fortanix demands architectural changes, not just a policy checkbox.
