Security Officers typically work for a variety of businesses or private entities. These include private homes, business parks, factories, warehouses, pharmaceutical plants, hospitals, shopping malls or government buildings. They work closely with other Security Officers to uphold security procedures, identify potential entry points for trespassers and resolve disputes between visitors or employees accordingly. Their job is to study building blueprints and notify officials of any suspicious activities. They may also be responsible for apprehending trespassers and detaining them until law enforcement arrives.
