ProvenRun ProvenHSM vs QuintessenceLabs Product Portfolio: Side-by-Side Comparison (2026)

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.

QuintessenceLabs Product Portfolio

Enterprise and mid-market security teams preparing for post-quantum cryptography will find real value in QuintessenceLabs Product Portfolio because it delivers vendor-neutral key management with genuine PQC crypto-agility instead of forcing a single vendor's algorithm roadmap. The qConnect suite supports NIST-approved post-quantum algorithms across ETSI 014, Cisco SKIP, and Nokia protocols, while Common Criteria Certification and NIST 800-90B validation on the qStream QRNG remove guesswork from compliance audits. Skip this if your organization needs a pure HSM replacement for symmetric key operations; Quintessence Labs is built for teams already committed to quantum-safe migration and willing to integrate specialized hardware like their CV-QKD optical links, not for plug-and-play key vault scenarios.
