Post-Quantum Quantum Safe Platform vs QiSpace™ SEQUR: Side-by-Side Comparison (2026)

Post-Quantum Quantum Safe Platform

Enterprises and mid-market organizations with hybrid infrastructure and near-term crypto-migration urgency should evaluate Post-Quantum Quantum Safe Platform for its modular approach to identity, VPN, and messaging protection without rip-and-replace demands. The platform implements RFC9370 hybrid classical-plus-post-quantum encryption across multiple attack surfaces, covers NIST CSF 2.0 authentication and data security functions, and maintains backward compatibility with legacy systems, which matters in organizations where forklift upgrades aren't realistic. This is not the tool for teams still evaluating whether quantum risk justifies budget allocation; Post-Quantum assumes you've already decided to act.

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.
