    Mapping the Supply Chain: A Faster Path to Organizational Resilience

    19/03/2026 | 38 mins.
    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

    05/03/2026 | 37 mins.
    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.

    Post-Quantum Negligence: When Inaction Becomes Legal Exposure

    19/02/2026 | 37 mins.
    Post-quantum risk is no longer a distant technical concern. It is an emerging legal exposure. In this episode of Shielded: The Last Line of Cyber Defense, host Jo Lintzen speaks with Darren Bender, a US litigation attorney and Chief Litigation Officer in the post-quantum cryptography sector. Darren introduces the concept of post-quantum negligence and explains how quantum threats intersect with foreseeability, duty of care, and negligence law. He walks through how courts may evaluate Harvest Now, Decrypt Later risk using expert forecasts, Mosca’s theorem, and the Learned Hand test. He also explains why financial services may be first to face litigation and what governance evidence organizations must begin documenting now to defend decisions made today.

    Compliance Deadlines, Customer Reality, and the Case for (embedded) TLS1.3

    05/02/2026 | 33 mins.
    Post-quantum cryptography does not fail because the math is hard. It stalls because systems are old, upgrades feel risky, and organizations struggle to explain the work in business terms. In this episode of Shielded: The Last Line of Cyber Defense, host Jo Lintzen speaks with Jan Schaumann, Chief Information Security Architect at Akamai Technologies, about how PQC migration actually unfolds inside a global platform. Jan explains why TLS 1.3 is the real prerequisite, why Akamai chose a slower, opt-in rollout, and how PQC becomes a forcing function for long-term crypto agility.
