PQC Compatibility Matrix

Post-quantum cryptography support across the Cisco portfolio

Which Cisco platforms are quantum-safe — and in which release?

Think of it like the optics compatibility matrix, but for post-quantum cryptography. Every entry is transcribed from Cisco's Quantum-Safe Communications Roadmap and public config guides — nothing is inferred.

PQC has two layers — and a platform can have one without the other

Cisco splits quantum-safe into two tracks. The software layer ships in a release; the hardware layer needs a physical root of trust. Having the software does not mean the box can do hardware-rooted PQC.
