Cybersecurity Expert | Former FBI Operative | Counterintelligence Specialist
Imagine working side by side with a traitor, knowing your every move could expose him or cost you everything. That was Eric O’Neill’s reality as the young FBI operative who helped bring down Robert Hanssen, America’s most notorious spy.
Our consultants would be happy to advise you on how best to tailor the narrative to your specific target audience.
Eric O’Neill is a cybersecurity expert, attorney, and former FBI operative best known for his pivotal role in capturing Robert Hanssen, the most damaging spy in US history. As a young FBI agent, Eric was assigned to an extraordinary undercover mission: to work directly under Hanssen and gather the evidence that would end his 25-year espionage career with Russia. The gripping true story was later depicted in the film Breach and in Eric’s acclaimed book Gray Day: My Undercover Mission to Expose America’s First Cyber Spy.
With decades of experience at the intersection of espionage, national security, and cybersecurity, Eric is now a sought-after speaker for global organisations, including AT&T, FedEx, Honeywell, Bayer, McKinsey, and Salesforce. His keynotes blend real-world stories from inside the FBI and the dark web with practical strategies to protect companies and individuals from cyberattacks—an escalating threat that today rivals the world’s largest economies.
Eric is the founder of The Georgetown Group, a premier investigative and security consultancy in Washington, DC, specialising in counterintelligence operations, economic espionage, AI-driven cyberattacks, and corporate risk assessment. He also co-founded Nexasure AI, a cutting-edge venture dedicated to defending organisations against the next generation of digital threats.
A regular media commentator, Eric has been featured on CNN, NPR, Fox, C-SPAN, TechCrunch and more, offering expert insights on espionage and cybersecurity. He holds degrees from Auburn University and George Washington University School of Law, and his book The Invisible Threat: Secrets from a Spyhunter in an AI World (HarperCollins, 2025) will explore the next wave of AI-fuelled risks facing governments and businesses alike.
Dynamic, engaging and deeply informed, Eric empowers leaders and teams to understand, anticipate and neutralise threats before they strike—transforming fear of the digital unknown into strategies for resilience and security.
