On the 39th episode of Enterprise AI Defenders, hosts Evan Reiser (CEO and co-founder, Abnormal AI ) and Mike Britton (CIO, Abnormal AI ) sit down with Mark Ballister , CISO at Montefiore Health System , to discuss governing AI risk in a hospital system. Mark shares how his team flipped the default from "no" to "yes, with controls," why work-versus-web toggles are a quiet exposure point, and how his own security team produced 22,000 lines of AI-generated code for an internal risk-evaluation model. Quick Hits from Mark: On the AI governance posture: "We don't look to say no. We look to say yes, as long as we can put controls around it." On the Microsoft Copilot work-versus-web toggle: "By just clicking that button that says 'web,' you are no longer protected." On bringing AI inside the security team: "It wrote all…22,000 lines of code." Book Recommendation: The One Minute Manager by Ken Blanchard and Spencer Johnson Like what you hear?
