Security Guards keep customers and employees safe at businesses, malls and events. Private Security Guards usually occupy one of two positions: static guards, who remain on watch in a single location, or mobile guards, who patrol the grounds and make sure no one is in an unauthorized area.

Security Guards are called when someone makes threats, shoplifts or otherwise causes trouble. While some guards have the power of arrest, others detain lawbreakers until the local police arrive. Similar security jobs include positions such as armed security guards.
