How to get a security guard license in Massachusetts

Massachusetts licenses security companies rather than individual unarmed guards; the licensing agency is the Massachusetts State Police: the colonel of the state police grants watch, guard or patrol agency licenses (M.G.L. c. 147, s. 25). Employers explain what their own guards need.
