The Domestic Security Alliance Council, or DSAC, is a security and intelligence-sharing initiative between the FBI, the Department of Homeland Security, and the private sector. Created in 2005, DSAC enables an effective two-way flow of vetted information between the FBI and participating members to help prevent, detect, and investigate threats impacting American businesses and U.S. economic and national security. DSAC members include some of the nation’s most respected companies.
