The Convergence Crisis: Protecting Critical Services from Dual Physical–Cyber Assaults

Sumnicht advises government agencies, critical infrastructure operators, and industry leaders on securing operational technology (OT), industrial control systems (ICS), Internet of Things (IoT), and converged physical and cyber environments. She is widely recognized as a leading authority on protecting critical infrastructure from emerging cyber threats, particularly those affecting transportation, utilities, public safety, and smart city ecosystems.

Sumnicht brings more than three decades of experience spanning cybersecurity, physical security, networking, and critical infrastructure engineering. She began her career at NASA Ames Research Center, where she participated in one of the first incident response efforts during the 1988 Morris Worm attack—an experience that helped shape her lifelong focus on cybersecurity. She has since held technical and leadership positions with organizations including Lockheed Martin, Cisco Systems, and numerous public-sector agencies. Prior to her current role, Sumnicht served as Chief Urban Technology Architect for New York City Cyber Command. There, she led cybersecurity initiatives for the city's industrial control systems and IoT infrastructure, overseeing the ICS/OT Simulation and Testing Laboratory and the IoT Penetration Testing Laboratory.
