Mr. Koshy is CISO for Indian Health Service, an enterprise serving 2.5 million American Indian and Alaska Native people, overseeing risk management, compliance, incident response and modernization. Within nine months, he stood up a 24/7/365 Cybersecurity Operations Center, unifying defenses across over 170 care sites with zero trust principles, machine-learning threat detection and real-time analytics. Mr. Koshy couples technical rigor with cultural stewardship, mentoring a diverse cyber workforce and embedding sovereignty-aware governance that respects tribal priorities. Thanks to his leadership, the impact of the organization’s cybersecurity operations center was recognized with Government Executive and Nextgov/FCW‘s “Fed100” award in 2025. He advises the U.S. Department of Health and Human Services CISO council and advances workforce development while hardening critical clinical infrastructure. His approach is informed by earlier federal and consulting roles in incident response, information system security officer work and enterprise risk.
