Why Full-Stack Post-Quantum Cryptography Cannot Wait
Cisco, Wednesday, April 1st, 2026
As large enterprises modernize their networks for the AI era, one challenge stands out: the looming risk posed by quantum computing. At Cisco Live 2026 Amsterdam, Cisco responded by introducing what we describe as the industry's first full-stack post-quantum cryptography (PQC) architecture.
This solution applies quantum-safe cryptography across every layer-from device integrity at boot to data in transit protection for critical connections-using National Institute of Standards and Technology (NIST)-approved quantum-resistant algorithms. For network engineers and security architects, this marks the most significant cryptographic leap in more than two decades.
