About Us


DCSA is the security agency in the federal government dedicated to protecting America’s trusted workforce and trusted workspaces — real or virtual. DCSA joins two essential missions: Personnel Vetting and Critical Technology Protection, supported by Counterintelligence and Training, Education and Certification functions. DCSA services over 100 federal entities, oversees 10,000 cleared companies, and conducts approximately 2 million background investigations each year.

Personnel Vetting: DCSA’s Personnel Vetting mission delivers efficient and effective background investigations, continuous vetting, and adjudications to safeguard the integrity and trustworthiness of the federal and contractor workforce. DCSA conducts background investigations for 95% of the federal government, including 105 departments and agencies. Additionally, DCSA adjudicates 70% of the federal government’s adjudicative determinations.

Critical Technology Protection: DCSA provides oversight to approximately 10,000 cleared companies under the National Industrial Security Program (NISP), ensuring that the sensitive and classified U.S. government information they are entrusted with and the critical technologies they develop are properly protected. DCSA ensures that companies are adequately protecting their facilities, personnel, and associated IT systems from attacks and vulnerabilities.

Counterintelligence: Counterintelligence crosscuts both the Personnel Vetting and Critical Technology Protection missions to identify and stop attempts by our nation’s adversaries — foreign and domestic — to steal sensitive national security information and technologies, keeping U.S. government leaders and stakeholders informed of these threats.

Training, Education and Certification: DCSA is comprised of nationally accredited training centers that provide security training, education, and certification products and services for security professionals across the federal government and industry.
