Defense Counterintelligence and Security Agency

**Our Role** We protect America's trusted workforce, trusted workspaces, and classified information. To do so, we have two fundamental missions: personnel vetting and industrial security. Supporting these two core missions are counterintelligence and insider threat and security training. For over 50 years, our agency has used each of these missions to meet the threats of our nation's adversaries. **How We Serve** DCSA is the largest investigative service provider in the federal government supporting over 100 federal entities. We oversee 12,500 cleared facilities under the National Industrial Security Program (NISP). We rely on the following directorates to ensure the security of our nation's technologies and information: **Personnel Vetting:** We deliver efficient and effective background investigations, continuous vetting, and adjudications. In doing so, we safeguard the integrity and trustworthiness of the federal and contractor workforce. We conduct background investigations for 95% of the federal government, including 105 departments and agencies. We also adjudicate 70% of the federal government's adjudicative determinations. **Industrial Security:** At DCSA, we oversee 12,500 cleared facilities under the National Industrial Security Program (NISP). We make sure companies are protecting their facilities, personnel, and associated IT systems from attacks and vulnerabilities. **Counterintelligence and Insider Threat:** Counterintelligence and insider threat supports both our personnel vetting and industrial security missions. Counterintelligence focuses on foreign insider threat, while Insider threat is focused on internal threat. In this mission center, we identify and stop attempts by our nation's adversaries to steal sensitive national security information and technologies. **Security Training:** Our agency is comprised of nationally accredited training centers. These centers provide security training, education, and certifications for security professionals across the federal government and industry.
