Arqit SKA-Platform vs Wultra Mobile-First Authentication: 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.

Wultra Mobile-First Authentication

Mid-market and enterprise teams handling sensitive transactions will get the most from Wultra Mobile-First Authentication because its push-notification and transaction-signing flows eliminate phishing attacks that plague traditional MFA. NIST-endorsed post-quantum cryptography built into the platform means you're protected against cryptanalytically relevant quantum computers without rearchitecting later. Skip this if you need passwordless auth that works equally well across web, mobile, and physical access; Wultra is explicitly mobile-first and will feel constraining for organizations running mixed authentication ecosystems.
