The General Directorate for Internal Security, DGSI, is a French security agency. It is charged with counter-espionage, counter-terrorism, countering cybercrime and surveillance of potentially threatening groups, organisations, and social phenomena.
The agency was created in 2008 under the name Central Directorate of Interior Intelligence, DCRI, merging the Direction centrale des renseignements généraux (RG) and the Direction de la surveillance du territoire (DST) of the French National Police. It acquired its current name in 2014, with a small structural shift: contrary to the DCRI which was part of the National Police, the DGSI reports directly to the French Ministry of the Interior.
The DGSI is headed by General Director Patrick Calvar. The agency is informally known as the "RG", a nickname formerly used for the Direction centrale des renseignements généraux which merged into it.
