Dan Sigmond is a former FBI Supervisory Special Agent and U.S. Air Force officer with 35 years of combined military and federal service, more than 20 of them leading white-collar, financial crime, and cyber-enabled investigations — securities fraud, insider trading, money laundering, wire and bank fraud, corporate embezzlement, business email compromise, and cross-border financial crime.
His caseload has included the Lehman Brothers auction-rate securities collapse in the Eastern District of New York, insider trading matters tied to the Galleon Group crackdown and to confidential information taken from the Walt Disney Corporation in the Southern District of New York, and the disruption of an Aryan Brotherhood of Texas access-device fraud and identity-theft enterprise. He led "Operation Jamaican Knights," an international lottery-fraud scheme targeting elderly victims, and PPP fraud investigations that traced and seized more than $1 million in COVID-relief proceeds — alongside numerous business email compromise and wire-fraud matters resolved through rapid tracing, freezing, and recovery of funds for victims.
Mr. Sigmond served in FBI field offices and at FBI Headquarters, where he directly supported the Bureau's Internet Crime and Complaint Center (IC3) and InfraGard national initiatives. Before the FBI, he spent 14 years as a U.S. Air Force officer, including combat deployments during Operation Enduring Freedom and Operation Iraqi Freedom leading cyber defense, intelligence, and reconnaissance initiatives.
His work has been featured by American Greed and National Public Radio, and he's a frequent speaker on financial crime and cyber-enabled fraud at law enforcement, industry, and executive forums. He founded Special Agent Advisory Group to bring that same government-grade insight to corporations, family offices, financial institutions, law firms, executives, and private clients who need experienced judgment on complex risk, fraud, security, and investigative matters.
