Governing AI Risk in Healthcare with Montefiore Health System CISO Mark Ballister

On the 39th episode of Enterprise AI Defenders, hosts Evan Reiser (CEO and co-founder, Abnormal AI [https://abnormal.ai/]) and Mike Britton (CIO, Abnormal AI [https://abnormal.ai/]) sit down with Mark Ballister [https://www.linkedin.com/in/mark-ballister/], CISO at Montefiore Health System [https://montefioreeinstein.org/], 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."

Identity Is the Perimeter in AI-era Fraud with Lockton Global CISO TJ Mann

On the 38th episode of Enterprise AI Defenders, host Mike Britton talks with TJ Mann [https://www.linkedin.com/in/tjmann1/], Global Chief Information Security Officer at Lockton [https://global.lockton.com/us/en]. TJ argues the fastest path to resilience is not chasing every shiny tool; it is treating identity, APIs, and SaaS configuration as the new frontline, because attackers “don’t need to breach your network anymore,” they need one compromised identity, integration, or misconfiguration. He also breaks down how AI shifts email and impersonation risk toward hyper-personalized social engineering, and why Lockton is investing heavily in employee awareness, muscle memory for reporting, and identity-first controls to keep fraud from becoming a business process. Quick hits from TJ: On AI-driven impersonation: “We are seeing… hyper personalized social engineering… deepfake voice or face or audio or video or both.” On what changed in cloud security: “Identity… is the new perimeter.” On what attackers really need now: “The bad guys don’t need to breach your network anymore. They just need to compromise one identity, one integration or one misconfiguration.” Recent Book Recommendation: Ikigai by Héctor García and Francesc Miralles Like what you hear?

Fraud Moves Faster With AI, Verification Must Too with KPMG US CSO Matt Posid

On the 37th episode of Enterprise AI Defenders, hosts Evan Reiser and Mike Britton talk with Matt Posid [https://www.linkedin.com/in/matthew-posid/], Chief Security Officer at KPMG US [https://kpmg.com/us/en.html]. AI accelerates the attacker’s playbook by increasing overall capability and reducing the time between vulnerability discovery and exploitation. Matt explains why KPMG consolidated cyber, insider risk, physical security, life safety, resilience, and third-party risk into one enterprise security program, and how defenders can keep up by pairing strong controls with AI-enabled workflows and clear governance. Quick hits from Matt: On how AI changes the threat curve: “AI is really good at a couple of things. It is really good at making people better, and it’s really good at making people faster.” On deepfakes and why fundamentals still work: “The controls we’ve had to protect against non AI-based attacks are still, in many cases, effective against the AI-based variants.” On the defender’s response, fight at AI speed: “If the bad guys are using certain tools, the good guys probably have to also, in order to keep up with the capabilities, the velocity that we need to defend.” Recent Book Recommendation: Unreasonable Hospitality by Will Guidara [https://www.enterprisesoftware.blog/book-club/unreasonable-hospitality] Like what you hear?

Secure by Design AI for a Modern Utility with Eversource Energy VP & CISO Chris Leigh

On the 36th episode of Enterprise AI Defenders, hosts Evan Reiser and Mike Britton talk with Chris Leigh [https://www.linkedin.com/in/chris-leigh-7b25b42/], VP and Chief Information Security Officer at Eversource Energy [https://www.eversource.com]. Chris leads security for a regulated, high-stakes utility serving millions across New England. He also owns AI in an uncommon org design that he uses to prove a point: governance does not have to slow innovation if it is built like an engineering function, with repeatable guardrails and clear pathways to ship. Quick hits from Chris: On shipping AI faster with standardization: “And that’s allowed us to accelerate our time to delivery by orders of magnitude of three months, down to four weeks, down to two weeks for various sprints.” On preventing outages with drone inspection: “We’ve put some patterns out on this that allows us to better bring in the imagery and run it through our models and pick up damaged components or hotspots in the wires, which allows us to schedule and do repairs before we actually have power outages.” On transforming threat intel into action for the SOC: “Any IOCs get popped into our tools automatically.” Recent Book Recommendation: Outlive: The Science and Art of Longevity by Peter Attia, MD Like what you hear?

On the 35th episode of Enterprise AI Defenders, hosts Evan Reiser (co-founder and CEO, Abnormal AI) [https://abnormal.ai/] and Mike Britton (CIO, Abnormal AI [https://abnormal.ai/]) talk with Adam Keown [https://www.linkedin.com/in/adamkeown/], Chief Information Security Officer at Eastman Chemical Company [https://www.eastman.com/en]. Adam draws on a career in law enforcement and global enterprise security to explain how Eastman is safeguarding life-critical manufacturing through identity-first defense, AI-informed education, and resilience engineering, staying ahead of a dynamic threat landscape. Quick hits from Adam: On aligning cyber with manufacturing outcomes: “Cybersecurity here at Eastman has two main pillars: make sure the business continues running, and protect our intellectual property. That gives us an advantage in the market.” On evolving attack surfaces: “Identity is the new attack surface, and privilege is the blast radius.” On adaptive education: “One of the nicest compliments I’ve gotten was a VP saying: ‘Your security newsletter is so concise it’s faster to read than to file away’.” Recent Book Recommendation: How to Know a Person by David Brooks [https://www.enterprisesoftware.blog/book-club/how-to-know-a-person] - -  Like what you hear?
