Post-Quantum Quantum Safe Platform is a commercial post-quantum cryptography solution by Post-Quantum. QSE Cloud Storage (QSE CDS) is a commercial post-quantum cryptography solution by QSE Group. Features, integrations, deployment and the company behind each one, side by side.
What our shortlists say about the one we picked.
Best for: Enterprises needing quantum-safe VPN, messaging, and identity in one suite
The modular architecture covering identity, VPN, and messaging in one platform is convenient but also means you are buying a suite rather than best-of-breed components. If you only need quantum-safe VPN, you are still buying into the broader platform. The backward compatibility with legacy infrastructure and hybrid classical and post-quantum approach means you do not have to rip and replace existing systems, which is the right design for any realistic enterprise migration.
