Certifying the future; synchronizing EUDI wallets and quantum-readiness

2026/07/23

The European Digital Identity Wallet (EUDI wallet) represents one of the largest shifts in digital governance, aiming to give citizens secure control over personal credentials across member states. However, deploying high-assurance trust architectures while preparing for post-quantum cryptography presents major technical hurdles for hardware vendors, service providers, and certification bodies. In this episode of Shielded: The Last Line of Cyber Defense, host Johannes Lintzen sits down with Wei Yuan, lab manager and director of operations at Applus+ Laboratories. Wei outlines the structural trade-offs between local security elements and remote HSM deployments, the challenge of building crypto agility into hardware, and why the European Commission timeline leaves zero room for delay.

Discover how browser-based cryptographic tools and AI help organizations understand upcoming global timelines, test new algorithms such as ML-KEM without friction, and prepare for the quantum threat.

Phased Timelines: DSCI roadmap for India's PQC migration

2026/06/04

The episode discusses India’s ambitious roadmap for quantum migration. The guests explore the aggressive 2029 deadline for critical infrastructure and the broader strategy for building a quantum resilient society. This conversation provides a detailed look at how one of the world’s largest digital economies is preparing for the quantum threat.

Curing Inventory Paralysis: Perfect Data is the Enemy of real-world Progress

2026/05/21

Antti Ropponen, Global Quantum Safe Transformation Leader at IBM Consulting, explains why the current shift toward post-quantum cryptography mirrors the early days of cloud migration. He details how organizations can avoid common pitfalls like inventory paralysis and explains why successful transitions require an organizational shift rather than just a technical update.

Moving From Awareness To Action: The Board's Role In Organizational Resilience

2026/05/07

Louise Davey, President of LDIQ and author of Quantum How, joins the show to discuss why the transition to post-quantum cryptography is fundamentally a challenge of organizational governance rather than just a technical upgrade. Drawing on her unique perspective as a former experimental nuclear physicist, she explains how leaders can translate complex technical threats into the business language of risk and resilience. This episode provides a roadmap for executives to bridge the gap between technical practitioners and executive leadership to ensure long-term viability.

RSA Conference 2026: Views on quantum-safe migrations

2026/04/16

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

2026/04/09

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

2026/03/19

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

2026/03/12

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

2026/03/05

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

2026/02/19

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

2026/02/05

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.
