Hardware Is the Hidden Risk: Ferhat Yaman on PQC, Side-Channel Attacks, and AI Privacy
What if your hardware is leaking secrets before your software even boots? In this episode of Shielded: The Last Line of Cyber Defense, Johannes Lintzen sits down with Ferhat Yaman, a security researcher at AMD’s Product Security Office, to explore the front lines of post-quantum cryptography, hardware vulnerabilities, and AI privacy. From electromagnetic side-channel attacks to homomorphic encryption, Ferhat shares practical insights from years of research and testing across AMD, academia, and open source projects. Learn what it takes to build and test hardware for a post-quantum world.

The biggest risk to PQC migration is you (and other humans)
What if the biggest threat to your cybersecurity strategy isn’t quantum computing, but humans? In this episode of Shielded: The Last Line of Cyber Defense, host Johannes Lintzen welcomes Professor Bill Buchanan, OBE, FRSE, a global leader in applied cryptography, digital trust, and secure system design. Bill shares the origins of public key cryptography and the challenges of migrating beyond RSA and ECC. Learn why cryptographic agility is essential, where the biggest vulnerabilities lie, and how standards like FIPS 140 and TLS are laying the groundwork for a secure future. Expect blunt truths, clear insights, and an urgent call for better systems, smarter engineers, and more public understanding.

The Crypto Agility Paradox: When Hardware Becomes Your Security Bottleneck
How do you prepare for post-quantum cryptography when your devices will still be in the field 20 years from now? In this episode of Shielded: The Last Line of Cyber Defense, host Johannes Lintzen is joined by Cassie Crossley, Vice President of Supply Chain Security in the Global Cybersecurity & Product Security Office at Schneider Electric. Cassie shares the hard-earned lessons from a multi-year crypto agility program in one of the world’s largest OT environments. From supply chain transparency to legacy encryption risks, she breaks down what it takes to prepare critical infrastructure for the quantum era.

NCSC proposes its PQC transition timeline to UK Policy makers: guiding the UK to a quantum-safe future
Quantum readiness isn’t about “predicting when,” it’s about “preparing now.” In this episode of Shielded: The Last Line of Cyber Defense, host Johannes Lintzen sits down with Dr. Jeremy Bradley, Principal Technical Director at the UK’s National Cyber Security Centre (NCSC), to explore the UK’s newly released guidance on migrating to post-quantum cryptography. Jeremy shares why the NCSC chose a pragmatic, timeline-driven approach, how organisations can manage legacy infrastructure without fear, and why PQC migration is a cybersecurity challenge, not just a cryptographic one.

Your Hardware Refresh Is a Quantum Deadline with Mamta Gupta
You can’t patch your way out of quantum exposure, especially when your hardware refresh cycle is a cryptographic deadline. In this episode of Shielded, Johannes Lintzen sits down with Mamta Gupta of Lattice Semiconductor to explore how hardware-rooted security must evolve to meet the post-quantum challenge. Mamta unpacks the real-world threat of “Harvest Now, Decrypt Later,” explains why crypto agility is essential for long-lifecycle devices, and shares clear, actionable steps to build quantum resilience from silicon to software. Learn how FPGAs provide a reprogrammable, future-ready foundation, what CNSA 2.0 mandates, and why your next hardware refresh cycle may be your last chance to stay ahead. If your business touches critical infrastructure, long-life devices, or digital supply chains, this episode is your wake-up call.
