Abstract
Corporate governance models built 50 years ago were designed for physical assets, not dynamic digital infrastructure. Today, post-quantum cryptography requires board members and executives to rethink operational resilience before legacy encryption breaks.
In this episode of Shielded: The Last Line of Cyber Defense, host Johannes Lintzen sits down with Will Collison (HSBC), Louise Davey (LDIQ), Kevin Reifsteck (Microsoft), and Sarah McCarthy (Citi). Together, they break down why quantum risk is an urgent executive priority rather than a narrow technology glitch.
What you’ll learn
- Why quantum threats invalidate underlying digital trust assumptions rather than single vulnerabilities
- How the timing offset of harvest now, decrypt later breaks standard risk management frameworks
- Practical tactics from Microsoft on inventorying enterprise cryptography without overwhelming teams
- How HSBC leveraged real-world trials to secure C-suite buy-in and align with 2030–2035 global timelines
- The critical distinctions between post-quantum cryptography, quantum key distribution, and quantum computing
- How Citi builds internal champion networks across legal, compliance, and risk teams to drive action
