Post-Quantum Security for Future-Ready Data Centers

HEQA Security QBN-Member
Data centers form the foundation of today’s digital ecosystem—supporting cloud services, enterprise applications, and critical business operations. Organizations rely on them for continuity, scalability, and security. As cloud adoption accelerates, enterprises increasingly connect to cloud providers through data-center PoP, requiring seamless and secure data exchange. To maintain high availability and compliance, many companies operate multiple interconnected data centers—typically a primary site for real-time operations and a secondary one for backup. Cross-connects are essential to these operations, enabling fast, low-latency transfer of sensitive data between facilities and connected services. Because they underpin availability, reliability, and security across environments, they are among the most sensitive components in data-center infrastructure. If compromised, a cross-connect could expose mission-critical operations and customer data to significant cyber risks. With the rise of quantum computing, existing encryption methods face increasing vulnerability. QKD delivers future-proof key generation rooted in quantum mechanics, ensuring keys cannot be intercepted, measured, or replicated—even with quantum-computing capabilities. HEQA Security strengthens this further through a Defense-in-Depth approach, combining QKD with PQC to secure communications end-to-end—from on-premises systems to the cloud—ensuring resilience against both classical and quantum threats.

Bottleneck of SOTA

Current encryption methods are not quantum-safe and remain vulnerable to quantum-computing–driven “harvest now, decrypt later” attacks. Encryption solutions other than QKD are not proven secure against quantum-computing attacks.
