From Awareness to Action: The Blueprint for Quantum-Resilient Security | Garfield Jones
Quantum threats aren’t hypothetical, they’re operational risks hiding in your cryptographic stack. In this episode of Shielded: The Last Line of Cyber Defense, host Johannes Lintzen sits down with Dr. Garfield Jones from CISA to dive into the practical steps for post-quantum migration, making the case that waiting until 2035 is far too late. Dr. Jones breaks down his APA framework (Awareness, Preparedness, Action) and explains why organizations need to act now to secure their infrastructure against the quantum threat. Learn how to take inventory, align procurement, tackle legacy infrastructure, and embed PQC into your vendor strategy before the clock runs out.
