Although security officers differ greatly from police officers, military personnel, federal agents/officers, and the like, Australia and the United States have a growing proportion of security personnel that have former police or military experience, including senior management personnel. On the other hand, some security officers, young people in particular, use the job as practical experience to use in applying to law enforcement agencies. Here are some of the duties and functions of Security Guard.

Many security firms and proprietary security departments practice the "detect, deter, observe and report" methodology. Security officers are not required to make arrests, but have the authority to make a citizen's arrest, or otherwise act as an agent of law enforcement at the request of a police officer, sheriff, and others.

In addition to the methodology mentioned above, a private security officer's primary duty is the prevention and deterrence of crime. Security personnel enforce company rules and can act to protect lives and property. In fact, they frequently have a contractual obligation to provide these actions. Security officers are often trained to perform arrest and control procedures (including handcuffing and restraints), operate emergency equipment, perform first aid, CPR, take accurate notes, write detailed reports, and perform other tasks as required by the contractee they are serving.

Many security officers are required to go through additional training mandated by the state for the carrying of weapons such as batons, firearms, and pepper spray (e.g. the Bureau of Security and Investigative Services in California has requirements that a license for each item listed must be carried while on duty). Some officers are required to complete police certification for special duties.

Security personnel may also perform access control at building entrances and vehicle gates; meaning, they ensure that employees and visitors display proper passes or identification before entering the facility. Security officers are often called upon to respond to minor emergencies (lost persons, lockouts, dead vehicle batteries, etc.) and to assist in serious emergencies by guiding emergency responders to the scene of the incident, helping to redirect foot traffic to safe locations, and by documenting what happened on an incident report.

Patrolling is usually a large part of a security officer's duties. Often these patrols are logged by use of a guard tour patrol system, which require regular patrols. The most commonly used form used to be mechanical clock systems that required a key for manual punching of a number to a strip of paper inside with the time pre-printed on it.
