Financial Crimes Enforcement Network (FinCEN)

The Financial Crimes Enforcement Network (FinCEN) is U.S. government agency that maintains a network to prevent and punish criminals and criminal networks that participate in money laundering and other financial crimes.
FinCEN, administered by the United States Department of the Treasury, operates both domestically and internationally to collect and analyze information about financial transactions in order to combat domestic and international money laundering, terrorist financing, and other financial crimes.
It consists of three major players: law-enforcement agencies, the regulatory community, and the financial services community.
