The Defense Counterintelligence and Security Agency (DCSA) is the entity responsible for personnel security clearances, facility clearances, and safeguarding classified information within the United States defense industrial base. Therefore, contact from DCSA typically indicates an involvement with national security matters, such as a background investigation, security incident reporting, or verification of information related to a security clearance.
DCSA’s functions are vital to protecting sensitive government information and ensuring that individuals with access to classified materials are trustworthy and reliable. This mission is essential for national security and the integrity of defense programs. Historically, these functions were managed by various agencies before being consolidated under DCSA, reflecting the importance of a unified approach to counterintelligence and security.
