What is the primary function of private security guards?

The primary function of private security guards is to protect property, assets, and individuals. This role encompasses a variety of responsibilities, such as monitoring premises for unauthorized access, ensuring the safety of employees and customers, and safeguarding physical assets from theft or vandalism. Security guards are present to deter criminal activity through their visible presence and to respond effectively in emergencies or concerning situations.

Although other functions like enforcing laws and detaining suspects can be part of a security guard's duties, they primarily serve to maintain a safe environment and protect the interests of the organization or individuals they are hired to serve. Conducting investigations is also not their core responsibility; that typically falls under the domain of law enforcement or specialized private investigators. Therefore, protecting property, assets, and individuals encapsulates the essential purpose of private security guards.
