Professor Xavier Crettiez teaches a unique course at Sciences Po Saint-Germain, training both young students and active members of the French secret services in intelligence and global threats. The course, developed after the 2015 Paris terrorist attacks, aims to identify and counter various threats, including organized crime and political violence. It attracts interest from both intelligence agencies and private companies, with a notable increase in female students. The course emphasizes practical skills over romanticized notions of espionage.
