The Chemical Facility Anti-Terrorism Standards, or CFATS, is a program administered by the Department of Homeland Security with the aim of protecting “high-risk” chemical facilities across the United States.

Chemical companies seeking to comply with federal Chemical Facility Anti-Terrorism Standards (CFATS) regulations have focused almost entirely on using the Department of Homeland Security's Web-based Chemical Security Assessment Tool (CSAT) to create and submit a Site Security Plan.

With the establishment of the federal Chemical Facility Anti-Terrorism Standards (CFATS) regulations, security is a matter of regulatory compliance for the chemical industry in the United States for the first time in history.
