A security guard is a person employed by an organization or individual to protect their assets from a variety of hazards by enforcing preventative measures. These assets may include property, people, equipment, money, housing societies, etc. Guards protect them by maintaining a high-visibility presence to deter illegal and inappropriate actions. They may do that by looking for signs of crime or other hazards and taking action to minimize the damage. The actions can include warning and escorting trespassers off property, reporting incidents to clients, reporting to emergency services, and informing police or emergency medical services as appropriate.
