"Security is integrity."

— Citadel Security motto

Citadel Security, known more commonly as C-Sec, was the official law enforcement organization on the Citadel, and one of the three uniformed services of the Citadel Defense Forces. Beginning as a volunteer force, C-Sec was reformed into a professional law enforcement agency in 382 BCE, and in 299 BCE was merged with the Citadel Defense Forces. With all the powers and abilities of a police service on any other Council world, C-Sec enforced the law, policed the many Wards and kept the peace. Like other police services, it possessed a basic volunteer police division and the special tactics division, and was headed by an Executor who only answered directly to the Council or Spectres.
