Safeguard Your WAN From Quantum Computing Threats
Cisco, Tuesday, January 13th, 2026
Quantum computing is a present-day reality that's changing cybersecurity in fundamental ways. The encryption protecting our most sensitive data today won't stand a chance against powerful quantum attacks.
This means organizations should begin adopting post-quantum cryptography (PQC) solutions now to secure their data in transit. And because wide-area networks (WANs) carry so much mission-critical data, they are ground zero. This blog takes a look at key considerations for establishing quantum-safe protection in WAN infrastructure.
