Arqit Encryption Intelligence vs QiSpace™ SEQUR: Side-by-Side Comparison (2026)

Arqit Encryption Intelligence

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.

QiSpace™ SEQUR

Enterprise and mid-market security teams needing cryptographic entropy they actually control will find QiSpace™ SEQUR worth the deployment complexity; it's the only platform that generates quantum random numbers on-premises, distributes them with Shannon Perfect Secrecy guarantees via QPP technology, and lets you own the entropy stack end-to-end instead of trusting a vendor's black box. Gigabit-per-second throughput over standard internet infrastructure and support for air-gapped networks mean this scales to real production environments, not just proofs of concept. Skip this if your team lacks the infrastructure maturity to manage a hybrid entropy tier or if you need turnkey simplicity; Quantropi is selling sovereignty, which requires operational commitment.
