Don Freese spent three decades in the FBI — from post-9/11 casework through nation-state cyber operations and critical infrastructure defense, retiring as a senior executive. He then led as a North America security practice partner at PwC and served as global CISO of Digital Realty, a NYSE-listed data center REIT operating critical infrastructure worldwide. Today he advises as an independent: the buyer's chair on cybersecurity, the investigator's eye on fraud and misconduct, and the operator's realism on what actually deploys in live environments.
