RSA Conference 2026: Views on quantum-safe migrations
16/04/2026 | 54 mins.
Post-quantum cryptography has moved past the awareness phase. The challenge now is execution. In this episode of Shielded: The Last Line of Cyber Defense, Jo Lintzen speaks with Aisling Dawson, Senior Analyst at ABI Research, and Itan Barmes, Chief Strategy Officer at Qiz Security, live from RSA Conference 2026. They discuss why quantum conversations are losing visibility, what’s blocking progress, and why organizations are stuck between inventory, budget constraints, and ecosystem misalignment. The discussion explores cryptographic posture management, organizational readiness, regulatory pressure, and why starting imperfectly is better than waiting for complete visibility.
Breaking Silos: Resilience as a Cross-Functional Mandate

Quantum readiness is increasingly about execution. In this episode of Shielded: The Last Line of Cyber Defense, host Jo Lintzen speaks with Carolina Polito, a researcher at the Center for European Policy Studies and a PhD candidate in international relations. Carolina explains why post-quantum migration is less of a cryptographic problem and more of an organizational challenge. She outlines how institutions should move from inventory to prioritization, how to engage vendors effectively, and why coordination across governance, procurement, and standards will define the pace of transition. She also shares where organizations can begin today without overcomplicating the process.
Mapping the Supply Chain: A Faster Path to Organizational Resilience

Post-quantum migration appears to be a technology problem from the outside. Inside a global financial institution, it looks like a coordination challenge. In this episode of Shielded: The Last Line of Cyber Defense, Sarah McCarthy, Quantum Readiness Program Lead at Citi, shares how Citi's quantum readiness program has evolved since 2022. They discuss what their vendor survey is revealing about supply chain readiness, and why the first step toward quantum safety does not require a dedicated team or advanced algorithms. She also explains why migrating to PQC is fundamentally a coordination problem and what practical steps any organization can take today, regardless of size.
Why AI is accelerating both attackers and defenders: From MWC Barcelona
12/03/2026 | 1h 1 mins.
Artificial intelligence is reshaping cybersecurity on both sides of the battlefield. In this episode of Shielded: The Last Line of Cyber Defense, host Jo Lintzen speaks with two experts at Mobile World Conference in Barcelona. Amidst the buzz of the industry being in one place, they discuss the security landscape in the AI era. The guests are working at different layers; Geri Revay, Principal Security Researcher at Fortinet’s FortiGuard Labs, explains how cybercrime has evolved into a structured ecosystem where attackers specialize in different roles and services. Later in the episode, Haon Park, Co-Founder and CTO of AIM Intelligence, focuses on the emerging risks around AI systems themselves. As organizations rapidly deploy AI models, agents, and autonomous technologies, these systems introduce an entirely new category of attack surface. Together, the conversation highlights a critical shift in the security landscape. Attackers are moving faster through automation and specialization, while defenders must adapt to new forms of risk created by the technologies they are deploying.
Your Inventory Dashboard is Not a Migration Strategy

Post-quantum cryptography is often framed as an algorithm selection problem. Stefan Kölbl reframes it as something else entirely: a key management and lifecycle discipline challenge.

In this episode of Shielded: The Last Line of Cyber Defense, host Jo Lintzen speaks with Stefan, an information security engineer at Google, about what it actually takes to migrate cryptography across complex global systems at scale.

They explore why Store Now, Decrypt Later is treated as a real threat inside Google, why hybrid deployments were justified before final NIST standards, and why inventory dashboards alone won’t get organizations across the finish line. The real work, Stefan explains, lies in crypto agility, automated key rotation, lifecycle ownership, and safe-by-default developer frameworks.
