Financial institutions operate some of the world’s most interconnected and high-value networks, linking branches, trading floors, clearing systems, data centers, and cloud services. These environments rely on continuous, authenticated, and uncompromised data communication to support real-time payments, trading operations, and customer transactions. As quantum computing advances, the cryptographic foundations protecting these critical links are becoming increasingly vulnerable to “harvest now, decrypt later” threats. If intercepted, manipulated, or decrypted in the future, such breaches could expose transaction records, authentication keys, private account information and proprietary trading data.
HEQA Security’s Quantum Key Distribution (QKD) solutions address this challenge by generating quantum-secure keys that cannot be intercepted, replicated, or reconstructed—even with the capabilities of future quantum computers. QKD provides physics-based assurance for securing financial-services infrastructure.
Building on this, HEQA delivers a Defense-in-Depth architecture that combines QKD with Post-Quantum Cryptography (PQC), enabling financial institutions to secure communication flows end-to-end— from on-prem to cloud. This hybrid QKD/PQC approach not only strengthens resilience against quantum and classical attacks, but also supports long-term planning for emerging quantum-security regulations and industry standards.
