The End of Static Cryptography: What Leaders Must Understand Now
08-1-2026 | 20 Min.
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 Min.
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.
The Hidden Threat: Harvest-Now-Forge-Later and the Collapse of Digital Trust
04-12-2025 | 36 Min.
The timelines for post-quantum cryptography are tightening, and the real threat surface extends far beyond decrypting old data. In this episode of Shielded: The Last Line of Cyber Defense, host Jo Lintzen speaks with Konstantinos Karagiannis, Director of Quantum Computing Services at Protiviti and host of The Post-Quantum World podcast, about the attacker’s perspective on quantum risk and why the world must plan for more than harvest-now-decrypt-later. Konstantinos explains why harvest-now-forge-later attacks on code signing, software supply chains, and blockchain consensus represent the most powerful quantum-enabled vectors, and how the emerging five-day rule for breaking RSA-2048 reshapes threat modeling and urgency. Expect practical direction on identifying crown jewels, demanding vendor clarity, building crypto inventory, and framing post-quantum migration as a core cyber resilience priority rather than a future experiment.
Inside Microsoft’s Quantum Safe Program: Turning Policy into Practice
20-11-2025 | 34 Min.
Post-quantum security will reshape every system that depends on cryptography. In this episode of Shielded: The Last Line of Cyber Defense, host Jo Lintzen speaks with Kevin Reifsteck, Director for Critical Infrastructure Protection at Microsoft, about how governments and global enterprises can turn quantum-safe readiness from policy into practice. Kevin shares how Microsoft’s Quantum Safe Program sets clear timelines, embeds accountability across engineering teams, and helps customers prepare long before 2035. He unpacks what regulators must do to accelerate migration, how to prioritize long-lived systems, and why leadership commitment, not code alone, defines true quantum resilience.
Securing the Silicon: How HP Designed Quantum-Safe Hardware from the Ground Up
06-11-2025 | 36 Min.
Hardware defines trust. If its cryptography fails, no amount of software protection can recover it. In this episode of Shielded: The Last Line of Cyber Defense, host Jo Lintzen speaks with Thalia Laing, Principal Cryptographer at HP, about how HP engineered quantum-safe protection directly into the hardware root of trust. Thalia explains how her team launched the world’s first quantum-safe Secure Boot for business PCs, why hybrid RSA + LMS was the right bridge between certification and quantum resilience, and what it takes to safeguard firmware that can’t be patched in the field. Expect a grounded discussion on hardware-level migration, LMS parameter design, and the practical steps every enterprise can take to secure devices that will outlive today’s algorithms.
