CST VerdictShort answer
Mid-market and enterprise security teams managing distributed endpoints without quantum-resistant encryption should evaluate Arqit SKA-Platform if post-quantum cryptography is a compliance or procurement requirement within 18 months. The platform generates one-time-use symmetric keys at each endpoint using NIST ML-KEM algorithms, achieving per-session key rotation and perfect forward secrecy without centralized key storage, which directly addresses PR.AA authentication and PR.DS data confidentiality under NIST CSF 2.0. Skip this if your organization lacks the budget for hybrid deployment infrastructure or views post-quantum migration as a 2030+ problem; the tool solves a real threat but only for buyers already convinced quantum key distribution is urgent. Enterprise security teams preparing for post-quantum cryptography migration should start with AQtive Guard, which maps cryptographic exposure across your entire infrastructure and identifies which assets need rekeying first. The platform covers NIST PR.PS and PR.DS through cryptographic vulnerability mapping, giving you the threat inventory most organizations lack before they touch quantum-safe algorithms. Skip this if you need certificate lifecycle automation for today's RSA and ECDSA environments; AQtive Guard is built around tomorrow's problem, not managing your current PKI operations.
