What Does a Security Guard Do?

The work is built on three verbs: observe, deter and report. A visible guard discourages theft and trouble. An alert guard notices something unusual early. A good guard records it and tells the right person. Most of the day is quiet, and the value lies in what does not happen.

Many guards work at a door, gate, lobby or loading dock, checking who comes in. That can mean checking names against a list, looking at identification, issuing visitor passes, checking tickets or bags where the venue requires it, and turning away people who are not allowed. The guard follows the client's rules; they do not make them up.

On a patrol a guard walks or drives a route, checks doors and gates, looks for hazards such as unlocked entries, water leaks or fire risks, and notes anything out of place. Some sites use check points that the guard scans on each round so there is a record. Patrols suit large or multi-building sites where a single post cannot see everything.

A written record is one of the most useful things a guard produces. A log shows when rounds were done, who visited, what was found and what action was taken. If there is a break-in, an injury or a dispute, the log gives the client, the police and sometimes a court a clear account. Reports should be factual, timed and written as soon as possible after the event.

Police officers are government employees with powers of arrest and investigation. A security guard is a private person hired by a client, with the same basic rights as any citizen plus the client's authority over private property. Laws on detention differ by state, and guards are generally trained to call the police rather than act themselves. Our page on detention and arrest explains the general principles.

Unarmed guards do all of the work above without a firearm. Armed guards hold an additional license and carry a weapon, and are used for higher-risk work such as cash handling. Unarmed guards typically cost $35 to $60 an hour on XGuard and armed guards $55 to $95, with each professional setting their own rate.

Beyond the core tasks, guards often do smaller things that make a site run well. They greet visitors, give directions, help with lockups and openings, check that lights and doors work, escort staff to their cars at night, respond to alarms, and keep an eye on equipment deliveries. At an event they may help with queues, answer questions and assist first aid teams.

Guards also act as the eyes and ears of the client. A guard who notices a broken lock, a fire exit blocked by boxes or a person loitering near an entrance can prevent a bigger problem. That is why good guards are patient, observant and comfortable writing things down.

Finally, guards must know the limits of the job. They follow the client's written instructions, avoid physical contact unless safety requires it, and call the police or emergency services when something is beyond their role. Knowing when not to act is as important as knowing what to do.
