Shielded: The Last Line of Cyber Defense

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 encrypt...

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 a...

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 c...

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 pra...

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 ag...

In this special RSA 2025 edition of Shielded: The Last Line of Cyber Defense, host Johannes Lintzen gathers four leading voices from the world of hardware security to discuss a cornerstone technology powering the post-quantum migration: the Hardware Security Module (HSM). Featuring insights from Entrust, Thales, Futurex, and Utimaco, this episode breaks down how HSMs are evolving to support crypto...

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, Prep...

Your cryptography may be stuck in 2010, and attackers are betting on it. In this episode of Shielded: The Last Line of Cyber Defense, host Johannes Lintzen speaks with Hart Montgomery, Technical Director at LF Decentralized Trust, about how outdated cryptographic dependencies, hidden vulnerabilities, and poor crypto agility are putting critical systems at risk. From alarming audit findings in fina...

The countdown has begun: by 2035, all public-key cryptography must be quantum-safe. Are you ready? In this episode of Shielded: The Last Line of Cyber Defense, host Johannes Lintzen welcomes Dustin Moody, the mathematician leading NIST's post-quantum cryptography standardization project, for an in-depth discussion on why organizations must act now. Moody shares essential insights into the 2035 imp...

Quantum threats aren’t coming—they’re already here. In this episode of Shielded: The Last Line of Cyber Defense, host Johannes Lintzen talks with Rolfe Schmidt, the man behind Signal Messenger’s quantum-safe migration. Learn how Signal protected billions of messages by prioritizing Harvest Now, Decrypt Later risks and deploying hybrid encryption—before PQC standards were finalized. Whether you’re...

Is your organization truly prepared for the post-quantum era? In the premier episode of Shielded: The Last Line of Cyber Defense, host Johannes Lintzen is joined by Bas Westerbaan, Research Engineer at Cloudflare, to discuss why organizations must act now on post-quantum cryptography, how to navigate the two-phase migration process, and how to overcome key management, compliance, and performance c...
