The Defense Counterintelligence and Security Agency (DCSA) is under the authority, direction, and control of the Under Secretary of Defense for Intelligence. It protects America’s trusted workforce and trusted real and virtual workspaces. The DCSA joins two missions: personnel vetting and critical technology protection. Vetting personnel and protecting technology are supported by counterintelligence and training, education, and certification functions. The DCSA services over 100 Federal entities, oversees 10,000 cleared companies, and conducts approximately 2 million background investigations each year.

The DCSA ensures the safeguarding of classified information used by contractors on behalf of the DOD and other executive branch agencies under the National Industrial Security Program. It oversees the protection of conventional arms, munitions, and explosives in the custody of DOD contractors; evaluates the protection of selected private sector critical assets and infrastructures; and recommends measures needed to maintain operations identified as vital to the DOD. The agency makes clearance determinations for industry and provides support services for DOD Central Adjudicative Facilities. It provides security education, training, and proactive awareness programs for military, civilian, and cleared industry to enhance their proficiency and awareness of DOD security policies and procedures. The DCSA also integrates counterintelligence principles into security countermeasures missions and supports the national counterintelligence strategy.
