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.
The End of Static Cryptography: What Leaders Must Understand Now
08/01/2026 | 20 mins.
Post-quantum cryptography changes the rules of cybersecurity. This special episode of Shielded: The Last Line of Cyber Defense brings together experts from cryptography, security architecture, and risk to explain what comes next. The conversation clarifies that security can no longer rely on fixed algorithms or one-time upgrades. Organizations must design for constant cryptographic change, stronger governance, and disciplined implementation or risk losing security without realizing it.
Confidentiality vs Authentication: How Far the Web Has Actually Moved
18/12/2025 | 32 mins.
Post-quantum cryptography is not a future ambition. It is already embedded into the web’s core confidentiality protocols. In this episode of Shielded: The Last Line of Cyber Defense, host Jo Lintzen speaks with Sofia Celi, Senior Cryptography and Security Researcher at Brave, co-author of the MAYO signature scheme, and co-chair of an IETF working group driving global PQC standards. Sofia explains the two-speed reality of PQ migration: confidentiality is already deployed at scale through TLS 1.3 and hybrid KEMs, while authentication, signatures, and zero-knowledge-based identity systems remain in deep research. She shares how standards bodies are recalibrating after TLS 1.3, why multivariate signatures such as MAYO could reshape authentication, why European eID timelines miss critical cryptographic maturity gaps, and the first two steps any security team must take within the next year.
