Arqit Encryption Intelligence vs Certes DPRM: Side-by-Side Comparison (2026)

Short answer

Mid-market and enterprise security teams facing quantum-threat deadlines or regulatory crypto audits need Arqit Encryption Intelligence because it finds encrypted traffic across your actual infrastructure,cloud, SaaS, endpoints, legacy systems,then tells you which ciphers will fail and when. The platform maps your cryptographic inventory against compliance timelines and generates governance-ready reports aligned to NIST and international standards, which cuts months off migration planning. Skip this if your organization has minimal encryption dependencies or treats post-quantum cryptography as a five-year problem; Arqit is built for teams that need to act now. Mid-market and enterprise organizations handling sensitive data across hybrid networks need Certes DPRM for its crypto-segmentation approach, which isolates network traffic at Layer 4 using quantum-safe encryption rather than relying on perimeter controls alone. The platform's separation of duties between policy and key management, combined with NIST PQC compliance alignment, addresses the real governance gap most teams face when encrypting data in transit. Skip this if your priority is protecting data at rest or you need visibility into application-layer threats; Certes is strictly a network data protection play and doesn't offer the breadth of a full data security platform.
