Arqit SKA-Platform vs Metropolitan Tech Platform: Side-by-Side Comparison (2026)

Arqit SKA-Platform

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.

Metropolitan Tech Platform

Mid-market and enterprise teams managing distributed edge infrastructure with strict confidentiality requirements should evaluate Metropolitan Tech Platform for its formally verified data ingestion layer, which provides provable security guarantees rather than assertions. The two-layer quantum-safe encryption via MetroProtect and zero trust architecture cover all four relevant NIST CSF 2.0 functions,identity management, data security, infrastructure resilience, and asset management,without gaps. Skip this if your edge footprint is small or your compliance burden doesn't justify the operational complexity of a hybrid deployment; a three-person vendor also means you're betting on continued development velocity and support responsiveness.
