Special Interview With Lionel Liddy, CISO at Menlo Security

Browser Security in the Age of Agentic AI: Containment, Isolation, and the New CISO Reality

Host Jim Love introduces a #TrendingOnTheWeekend episode featuring David Shipley (Cyber Security Today, Beauceron Security) interviewing Lionel Liddy, CISO at Menlo Security, about AI-driven vulnerability discovery and why reactive security is failing as exploitation accelerates. Liddy shares his path from a University of Toronto PhD researching virtual machines to building Menlo's browser-security approach: an isolated remote "cloud browser" that prevents active web content from executing on endpoints and can also shield servers by forcing interactions through a controlled browser. They discuss CISOs struggling to keep up with rapid shifts, agentic AI risks in browsers and extensions, limits of LLM guardrails (including NIST's proof-like framing), and the compounding impact of pervasive bugs and technical debt. The episode closes with where to learn more at Menlo Security.
