A security guard's primary role is to ensure the safety and security of the premises they are assigned to. Their responsibilities include patrolling the area to monitor for suspicious activity, protecting the property from theft, vandalism, or other threats, and controlling access by verifying identities and checking credentials. They also monitor surveillance equipment, report incidents or safety hazards, and respond promptly to emergencies, such as fires or medical situations, by notifying authorities and providing assistance when necessary. In addition to these duties, security guards often offer customer service by helping visitors, answering questions, and directing them to the right locations. Their presence is essential in maintaining a secure and orderly environment for both the property and individuals on-site.
