Twenty-five years ago, Eric O’Neill went undercover inside FBI Headquarters in one of the most intense counterintelligence operations in U.S. history. He worked alongside Robert Hanssen, a top FBI counterintelligence agent who had been secretly spying for Russia for more than two decades. Every day was a psychological chess match that tested O’Neill’s focus, resilience, and skill. His work included securing and helping analyze Hanssen’s PalmPilot, providing the FBI with the critical evidence needed to bring the betrayal to light.

That experience shaped O’Neill’s career and his mission today, sharing firsthand lessons on detecting deception, confronting hidden risks, and thinking like a spy hunter. His story is not just about espionage, it is about vigilance, strategy, and understanding how threats can hide in plain sight.
