Sergio Caltagirone is a Professor of Practice at Georgia Tech’s Carter School of Public Policy, where he co-directs the Center for Digital Human Security and leads the Civilian Exposure Reduction Project (CERP), a partnership with the International Committee of the Red Cross developing practical ways to separate civilian from military users on the shared digital infrastructure both depend on during armed conflict. He came to that work after more than twenty years on the front lines of cyber threat intelligence. As Vice President of Threat Intelligence at Dragos he built the world’s first commercial industrial control system threat-hunting team, uncovering some of the most serious threats ever found against power, water, oil and gas, and manufacturing worldwide. Before Dragos he launched the Microsoft Threat Intelligence Center and served as one of the NSA’s earliest cyber threat intelligence analysts, and he co-created the Diamond Model of Intrusion Analysis, now a foundational framework across the field. At Georgia Tech he teaches cyber threat intelligence, threat hunting, and offensive cyber operations, and he founded the Threat Intelligence Academy, which has trained more than 750 practitioners worldwide.
