The Domestic Security Alliance Council (DSAC) is a strategic partnership between the U.S. government and the U.S. private industry that enhances communication and promotes the timely and effective exchange of security and intelligence information between the federal government and the private sector.

Its goal is to advance the FBI's mission of detecting, preventing, and deterring criminal acts by facilitating strong, enduring relationships among its private sector member companies, FBI Headquarters, FBI field offices, Department of Homeland Security (DHS) Headquarters and Fusion Centers, and other federal government entities. DSAC also expands the U.S. private sector’s ability to protect its employees, assets, and information by providing ongoing access to security information and a network of security experts, as well as continuing education for corporate chief security officers (CSOs) and intelligence analysts.

In the fall of 2005, a steering committee composed of CSOs from a number of the country’s largest corporations began meeting with Bureau officials and members of the State Department’s Overseas Security Advisory Council (OSAC) at FBI Headquarters. The committee’s objective was to create a domestic security organization modeled after OSAC to connect private sector security experts with each other and to serve as a vehicle for exchanging information with the Bureau. The FBI agreed to set up and lead this Domestic Security Alliance Council, which was officially approved by the FBI Director in December 2005.
