Security guards protect people, property, and facilities from theft, vandalism, and other threats. They monitor security cameras, control access, respond to incidents, and write reports. Modern security work increasingly uses AI-enabled surveillance, alarms, access-control systems, and other security technology.
A high school diploma or equivalent is typically required. Training and licensing requirements vary by location and may include security training, first aid, CPR, or specialized training for armed security work.
Security guards work in offices, stores, hospitals, schools, industrial facilities, airports, residential buildings, and other locations. The work can involve standing, walking, monitoring cameras, and responding to incidents. Evening, overnight, weekend, and holiday shifts are common.
Security remains important as organizations protect people, property, and information. AI-powered cameras, remote monitoring, biometrics, and access-control technology are changing the work, creating opportunities for guards who are comfortable with modern security systems.
