I lead World Wide Technology’s Global Cyber Field CTO Office and our AI, Application, API and Cloud Security Practice. We help enterprise and federal customers evaluate emerging threats, make security investments, and move from architecture to implementation. My role combines team leadership with customer advisory and hands-on technical work, drawing on WWT’s Advanced Technology Center, AI Proving Ground, and technology partners to validate what we recommend. A growing share of my work concerns adversarial AI. Frontier and open-weight models are accelerating exploit development and changing the economics of attack. Defenders have to reconsider how quickly they can interpret intelligence, authorize a response, and enforce it across their environments. I write and speak on these issues and contribute to WWT’s Defending at the Speed of AI initiative. My particular interest is in turning threat intelligence into defensive action fast enough to interrupt an attack. Before WWT, I built and led Lumen’s cybersecurity center of excellence and Black Lotus Security Group, with responsibility for threat research, engineering, data science, security operations, and advisory services. Our teams developed Lumen Defender, brought threat intelligence into AWS Network Firewall and Microsoft Sentinel, and collaborated with the FBI, Europol, Microsoft, and USCYBERCOM on major botnet disruptions, including Raptor Train. That work required sustained cooperation among researchers, engineers, commercial teams, and government partners to turn original research into products and operational results. During 21 years at Cisco, I built and led security product, services, and incident response organizations. My work included SecureX, Managed Threat Defense, and global security operations. Those experiences continue to shape how I lead, particularly the importance of understanding the technology well enough to make sound decisions and giving teams the direction and support to carry them through. I hold an active TS/SCI clearance with CI Polygraph, CISSP certification, and a Master of Engineering from NC State. I am the author of two O’Reilly books, Security Monitoring and SQL Injection Defenses.
