Signals from the front lines: Moving from recovery to autonomic resilience

In this episode, host and Cloudflare Field CIO Khalid Kark sits down with a powerhouse panel of CISOs and founders - Sounil Yu, Jerry Perullo, and Mario Duarte - to discuss a paradigm shift in cybersecurity: the move from traditional "backup-and-recovery" resilience to autonomic resilience.

As AI-enabled threats become more relentless, the panel argues that human-centric security operations must evolve. They explore the critical fault lines facing the C-suite today, from the challenges of autonomous decision-making and AI governance to the complexity of managing "nth-party" risk in a hyper-connected ecosystem. Whether discussing the OODA loop of AI agents or the reality of shadow AI in the enterprise, this conversation provides a blueprint for how leaders can stay ahead of the curve.
