About the Interagency Security Committee

Interagency Security Committee logoThe Interagency Security Committee is a collaborative organization that provides leadership to the nonmilitary federal community supporting physical security programs that are comprehensive and risk based.


People are safe and secure in federal facilities throughout the country.


We safeguard U.S. nonmilitary facilities from all hazards by developing state-of-the-art security standards in collaboration with public and private homeland security partners.
