Prior to 2011, the DSS Academy provided security training to Department of Defense (DoD) and other U.S Government personnel, employees of U.S Government defense contractors, and when sponsored by authorized DoD components, employees of foreign governments. In 2011, the CDSE Training Division assumed these functions.

CDSE Training Division operates under the management of the Defense Counterintelligence and Security Agency (DCSA), formerly the Defense Security Service (DSS) and focuses on the training and education of internal DCSA security workforce as well as external security professionals within industry and the U.S Government.
