Cathy Chan: Post-Quantum Security and the Shift Toward Crypto-Agility

Quantum computing is moving from theory to reality, and with it comes a fundamental shift in how organizations must protect long-lived and sensitive data.

In this episode, Cathy Chan from Cyberforce explains what Q-Day really means, why “harvest now, decrypt later” is already a live threat, and how enterprises can build crypto-agility before post-quantum standards fully enforce.

Clear, practical, and free from hype, this conversation gives security leaders a grounded view of quantum risk, emerging cryptographic changes, and the essential steps to begin preparing today with confidence.
