Arqit NetworkSecure is a commercial quantum security tool by Arqit. Quantanaut is a commercial quantum security tool by cyberzero. Compare features, ratings, integrations, and community reviews side by side to find the best quantum security 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 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 security teams managing cryptographic decay across complex supply chains need Quantanaut because it finds broken encryption and outdated TLS configs that vulnerability scanners skip entirely. The agentless discovery model means you map cryptographic risk using existing tool data without new agents, and the structured PQC transition guidance directly addresses NIST CSF 2.0's GV.SC supply chain requirement. Skip this if your organization hasn't inventoried cryptographic assets yet; Quantanaut assumes you know what you're protecting.
