Key results achieved through this project
The Challenge
A critical infrastructure company with defense supply chain exposure was required by contract and regulatory mandate to achieve quantum-safe communications. Their existing VPN relied on classical encryption vulnerable to Harvest Now, Decrypt Later (HNDL) attacks — a serious threat given sensitive operational and procurement data transmitted today could be decrypted by quantum adversaries in future. They needed rapid deployment without replacing existing network hardware.
Our Solution
Praxysai.com partnered with QryptShield to deploy a full quantum-safe communications infrastructure: QryptShield Quantum Safe VPN providing quantum-resistant encrypted tunnels (Kyber, Falcon algorithms) for all remote access and site-to-site communications, Quantum Secure Chat for protected internal communications, a hybrid deployment model alongside existing infrastructure, 24/7 security monitoring and incident response, and a tailored security operations training program.
