Ollie Whitehouse, CTO of the UK’s National Cyber Security Centre (NCSC), joins Code and Country to unpack what it really takes to secure a nation in the age of AI, ransomware, and quantum threats. Drawing from three decades of experience across public and private sectors, Whitehouse offers a candid assessment of the broken cybersecurity market, why the incentives are misaligned, and what meaningful defense should look like. He explores how governments and enterprises can better collaborate, the urgent need to catalog cryptographic dependencies, and why resilience must be built into business, not bolted on. Essential listening for CISOs, IT leaders, and architects navigating the new frontier of national-scale cyber defense.
