Contract security refers to an organization that vends their security services for an organization that needs to protect their assets using physical security (manpower) with a degree of technology, if applicable.


Most of the USA’s critical infrastructure systems are privately owned and are protected using private security officers (Strom et al. 2010). Large and small businesses, residential housing, educational facilities, governmental agencies, and other segments of business may decide for a variety of reasons to outsource security by hiring a company or guards to protect employees, property, and customers.
