Arqit SKA-Platform vs QSE Cloud Storage (QSE CDS): 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.

QSE Cloud Storage (QSE CDS)

Mid-market and enterprise teams storing sensitive data across distributed environments should evaluate QSE Cloud Storage (QSE CDS) if quantum-resistant encryption and decentralized architecture matter more than centralized backup simplicity. Hardware QRNG-based key generation validated to NIST SP800-22 and AES-256/RSA-4096 encryption provide genuine protection against harvest-now-decrypt-later attacks, and the zero-knowledge model means QSE Group itself cannot access your files. This is not the tool for buyers prioritizing ease of deployment or needing tight integration with existing enterprise backup stacks; decentralized IPFS storage requires operational maturity and acceptance of different management workflows than traditional cloud providers.
