Overview: The Security Department is responsible for all security at SCP Foundation facilities, being responsible for the safety of all personnel, anomalies, and equipment. SecDep is also responsible for capturing newfound SCPs that don't require the expertise of MTFs; the units that conduct these operations are called Recovery Teams.
They use a P90 and a Glock 17 as a sidearm.
As many of the anomalies they are assigned to are dangerous or unknowingly dangerous, the SciD usually utilizes Class-D personnel to perform designated tasks; commonly for research purposes. Many can result in death or extreme danger, which is typically where the Security Department steps in to eliminate the threat.
Much of the SciD's staff are recruited from various places within the scientific community, particularly those who discover something anomalous in their field of study. The SciD is occasionally stereotyped as having little to no morals, only being kept in check by the Ethics Committee; however, this is far from the truth, as most truly depraved staff are turned into Class-D or simply terminated.
While there are many other departments in the SCP Foundation dedicated to scientific studies regarding the anomalous, the SciD is mainly nondescript scientific research that isn't monitored by any specific department dedicated to a certain study.
