About Bill Thorn

Bill Thorn is CTO, Public Sector at Trellix. Location: Greater Tampa Bay Area, United States.

Crisis-tested strategic technologist who helps CEOs, boards, and public-sector leaders turn complex cyber, operational, and legal risk into clear enterprise strategy. My value is not simply building security programs but knowing what matters when risk becomes real, decisions are urgent, and the stakes are high. I bridge deep technical architecture, executive communication, commercial growth, regulatory expectations, and evidentiary resilience with the calm judgment of a former first responder and the discipline of a seasoned CISO/CTO. Across more than 20 years, I have built teams, platforms, intelligence capabilities, and resilient operating models that help organizations anticipate threats, protect mission-critical services, and lead confidently when the building is on fire.
