Security guards are professionals responsible for protecting property, assets, and individuals. They monitor premises, conduct patrols, and ensure safety by preventing unauthorized access. Security guards often work in various settings, including shopping malls, office buildings, and events. In addition to physical presence, security guards may use surveillance equipment and report incidents to law enforcement when necessary. Their training can include conflict resolution, emergency response, and first aid, making them essential for maintaining a secure environment in both public and private spaces.
