PQC vs. QKD: What Matters Now and What Can Wait

Описание: Quantum threats may feel distant, but your migration shouldn’t be. In this episode of Shielded: The Last Line of Cyber Defense, host Jo Lintzen talks with Will Collison, Interim Global Head of Cryptography at HSBC. Will explains why enterprises must start now and measure as they go, how to separate PQC, QKD, and quantum computing, and why cryptographic agility is the real objective. Expect practical guidance on executive buy-in, vendor dependencies, critical-system prioritization, and the cost logic that makes an early start the only rational choice.
