CISO Series Podcast

Jerich Beason, CISO at WM, leads operational technology security, while Edward Contreras, Frost Bank’s CISO, specializes in financial-sector cyber risk. They tackle AI’s accelerating attack velocity, adapting zero trust for OT, and the risks of autonomous agents. The discussion also explores build-versus-buy decisions, vulnerability prioritization, vendor due diligence, and why humans remain accountable when automation fails.

Alexandra Landegger, corporate CISO at RTX, and Jacob Combs, CISO at Tandem Diabetes Care, explore why recurring patches often signal deeper architectural flaws and technical debt. They unpack continuous attack-path assurance, the risks of AI-related disclosures amplified by Reddit, and how AI can return time to overwhelmed security teams rather than eliminate them. They also outline the cyber-risk questions every CEO should be ready to answer.

Chad Rubin, senior vice president of cybersecurity at Publicis Re:Sources, joins a lively discussion on making AI security practical. They explore why imperfect controls beat waiting for perfection, how to secure AI before transformation hardens, and whether shadow AI can move faster than approval processes. The conversation also covers guardrails for AI agents, zero trust, contrarian innovation, and finding opportunity by removing operational friction.

Jake Lorz, Cintas’ vice president of IT and CISO, joins the conversation on security’s identity crisis in an AI-powered workplace. They explore action-centric controls for agentic AI, why AI SOCs must fail safely, and how MFA exceptions can create dangerous account sharing. The discussion also covers data governance, over-permissioned information, institutional memory, and empowering teams without replacing human judgment.
