The Post-Quantum Quantum Safe Platform is a modular software suite designed to protect against "Harvest Now, Decrypt Later" (HNDL) attacks by implementing post-quantum cryptography across three domains: identity, data transmission, and encryption. **Identity Protection** Provides quantum-safe authentication and access management using multi-factor biometric authentication (via Nomidio) and quantum-resistant credential management. Includes an approval-as-a-service capability (Quorum) for managing authorised access to sensitive systems. **Hybrid PQ VPN** Secures data-in-transit against both classical and quantum-based attacks. Implements RFC9370, the IETF-ratified standard for multiple key exchanges in IKEv2, which the company authored. Supports interoperability with partner encryption systems and has been deployed in NATO production networks. **Quantum-Safe Messaging** An end-to-end encrypted messaging application using quantum-resistant encryption. Supports enterprise deployment, management, and protection of stored message archives. **Cryptographic Foundation** The platform is built on Classic McEliece, a code-based cryptographic algorithm and NIST Round 4 finalist. It introduces deliberate errors into the encryption process to eliminate exploitable patterns for quantum brute-force attacks. The algorithm has a documented 47-year security track record. **Architecture Principles** The platform follows a hybrid approach, combining classical and post-quantum algorithms simultaneously. It is designed to be crypto-agile, backward compatible with legacy infrastructure, and modular so components can be deployed independently or in combination.
