The primary role of security guards is safeguarding the client’s property. The security guards adopt a preventive approach rather than a reactive one meaning that they act as a deterrence to crime and disruptions on the assigned location by watching out for looming danger and suspicious activities or persons.

The security guards or security officers may be employed in a variety of settings, such as private premises, public building, museums, or banks. The duties may vary depending on the site they are deployed at, but the primary responsibility remains the same- to uphold security protocol.

Along with the preventive role, a guard is also equipped with a patrol guard tour system to report the on-site movements to maintain a proper record of the tasks performed during patrols, and incidents to avert a future recurrence. Also, it serves as a medium for alarm response, communication, and data collection and management.
