The prospect of quantum computers breaking widely used encryption is moving closer, while AI is creating new challenges around trust, identity, and governance. DigiCert’s Kevin Hilscher warns that organisations face a growing gap between awareness of post-quantum cryptography and action, with competing business priorities delaying preparation. Meanwhile, shadow AI and limited visibility into autonomous agents are creating fresh security risks.
Both Hilscher and Daniel Sutherland urge businesses to begin post-quantum preparation through cryptographic discovery, executive buy-in and governance, rather than waiting for a definitive Q-Day deadline. They also highlight the need to upgrade systems, build crypto agility, and automate certificate management as lifespans shrink. Australia has set an ambitious 2030 target for post-quantum migration, with organisations expected to develop transition plans now.
The discussion also explores how AI agents should be treated like employees, with verified identities, defined access privileges, and the ability to revoke trust when necessary. The executives argue that visibility, automation, and stronger policies will help businesses manage both emerging technologies – and avoid being caught unprepared as the threat landscape evolves.
