Supplemental Security Force

Campus Security Officers (CSOs)

CSOs are non-sworn officers who provide valuable adjunct safety and security services. The CSOs perform various roles that are preventative in nature and support our mission of providing a safe and secure environment.  They act as an extra set of eyes and ears for the patrol officers and are an additional resource to our community members. Under the supervision of the duty supervisor, CSOs patrol the buildings and grounds of the university, provide escorts and transportation for university personnel, enforce parking regulations and provide access control at various fixed points throughout the University.


Contract Security Officers

Contract security officers are non-sworn personnel who are used primarily at interior fixed positions at buildings on campus. Contract Security Officers work for Allied Barton, a private firm contracted by the university, to provide supplemental safety and security services. Allied Barton officers are posted at various buildings on the Medford/Somerville campus including Tisch Library, Tisch Sports Center, Cabot Center, Aidekman Arts Center and the TAB Building.
