In this episode of Shielded, 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.

Our CSO Ben Packman speaking at Web Summit, Lisbon November 12:05-12:25 on – "Quantum crossroads: Opportunity and risk in the next computing era."

How can you prove a private conversation ever happened? In modern secure messaging, the goal is "deniability"—ensuring no one can cryptographically prove you sent a message. This vital privacy feature is core to protocols like Signal's X3DH, but achieving it in a fully post-quantum world has been a major roadblock. A promising path forward involves 'split-KEMs' (a method for establishing secret keys), but previous approaches were too inefficient to be adopted. Our latest research, Sparrow-KEM, solves this efficiency problem. It makes this approach a viable way to upgrade the Signal protocol, making it fully resistant to quantum attackers. The results represent a significant leap forward...

Hardware defines trust. If its cryptography fails, no amount of software protection can recover it. In this episode of Shielded, Jo Lintzen speaks with Thalia Laing, Principal Cryptographer at HP.

In this episode of Shielded, Jo Lintzen speaks with Dr. Richard Searle, Chief AI Officer at Fortanix, about how confidential computing and a software-first model accelerate the shift to post-quantum cryptography.

PQShield and Quantinuum have developed a joint solution, combining Quantum Origin’s mathematically-proven Quantum Random Number Generation (QRNG) with PQShield’s FIPS-140-3-validated post-quantum cryptographic library in PQCryptoLib-SDK, for resilient post-quantum algorithms.

In this episode of Shielded, Johannes Lintzen speaks with Bruno Couillard, CEO and co-founder of Crypto4a, about his journey from designing the original Luna HSM to building the next generation of quantum-safe hardware.

We propose a hybrid formal verification approach that combines high-level deductive reasoning and circuit-based reasoning and apply it to highly optimized cryptographic assembly code.

This joint Guide with Cryptomathic outlines the critical challenges driving a major evolution in cryptographic key management, namely the threat of quantum computing and the growing complexity of multi-cloud environments

In this episode of Shielded: Jo speaks to Mike Silverman, Chief Strategy & Innovation Officer at FS-ISAC. Mike shares why treating cryptographic migrations as one-off projects leaves organisations exposed, how building inventories and risk-based models creates real readiness, and why crypto-agility, not quantum anxiety, is the foundation for long-term security.

In this episode of Shielded, we talk with Will Collison, Interim Global Head of Cryptography at HSBC. Will explains how to separate PQC, QKD, and quantum computing, and why cryptographic agility is the real objective.

What if quantum computing feels like a distant threat, but your timeline to prepare is already running out? We welcome Adrian Neal, Senior Director and Global Lead for Post-Quantum Cryptography at Capgemini.
