To mitigate potential FOCI, Thales Defense & Security, Inc., in concert with the DoD’s Defense Counterintelligence and Security Agency (DCSA), has agreed to a comprehensive series of controls and requirements set forth by the Proxy Agreement (the highest-level FOCI mitigation instrument), subject to oversight by the Government Security Committee (GSC) to ensure independent TDSI management. As such, TDSI is approved to work on the full spectrum of US Government classified and unclassified programs without restriction, and is positioned to support strategic partnerships in the development of key technologies for the defense market. Thales’ Proxy Agreement has been active since 1986, initially as Racal Communications, Inc., making it one of the longest-standing proxy agreements in the US National Industrial Security Program (NISP).
