All of our security officers must pass a background investigation that includes criminal, credit, and reference checks and drug screening. They must be of sound character, demonstrate good judgement, and present a neat and professional appearance. We hold our armed security officers to the highest level of standards. These officers must possess a minimum of two years security experience and successfully complete a firearms re-qualification program annually. They are also required to demonstrate knowledge of their legal authority and the limitations of an armed security officer. Additionally, Cambridge security officers are trained in the de-escalation of force, including how to take a non-violent approach using verbal skills to handle violent or potential violent situations.
