CST VerdictShort answer
Enterprise and mid-market security teams with hybrid networks facing quantum threats should deploy Arqit NetworkSecure to protect VPN tunnels against store-now-decrypt-later attacks before cryptographically relevant quantum computers arrive. The tool's split-trust key orchestration means Arqit itself cannot access your encryption keys, and compliance with NIST ML-KEM and NSA Commercial Solutions for Classified standards signals serious cryptographic rigor. Skip this if your network runs primarily on a single vendor's ecosystem or you need the tool to enforce zero-trust access control; NetworkSecure is narrowly focused on quantum-safe VPN hardening, not identity or microsegmentation. 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.
