PSI Security Service is a licensed security guard company in Atlanta, Georgia, providing armed and unarmed officers, vehicle and bike patrol, construction site security, lobby security, and temporary guard services across the Atlanta metropolitan area since 1989. As a locally owned and operated security guard company in Atlanta, we serve businesses of all sizes — from financial institutions and commercial buildings to warehouses, stadiums, and healthcare facilities.
Our officers are fully licensed by the State of Georgia under the Georgia Board of Private Detectives and Security Agencies. Every PSI officer completes state-required training, including CPR, loss prevention, behavioral response, and defensive driving, before deployment. We are one of the few security patrol companies in Atlanta that combines static guard deployment with 24/7 mobile vehicle coverage under a single, locally managed program.
Deploy the right level of protection for your site. All armed officers are Georgia-certified and matched to your specific risk profile.
Our Atlanta-based dispatch team operates around the clock. Emergency deployments can be mobilized within 24 hours across the metro area
No regional call centers. PSI’s management team is available directly to every client — a level of access that national companies simply cannot match.
Vehicle patrols use GPS-tracked mobile units with real-time communication with dispatchers, verified checkpoints, and digital incident reporting.
Unlike national chains that manage Atlanta accounts from out-of-state offices, PSI’s management team lives, works, and operates entirely within the metro area. When a client calls, they reach the people directly responsible for their security.
At PSI Security Guard & Security Patrol Service, we deliver value by understanding your requirements and providing outstanding security services, including uniformed officers, vehicle and bike patrols, construction security, temporary security, and more.

Atlanta businesses frequently experience after-hours trespassing, vehicle and cargo theft (particularly around logistics and distribution hubs), organized retail crime, construction site equipment theft, and unauthorized access to commercial properties. PSI recommends a layered security approach — combining uniformed officers, vehicle patrols, and access control measures — to deter, detect, and respond to these risks effectively.
PSI Security operates 24 hours a day, 7 days a week, with a dedicated local Atlanta dispatch team. For emergency or temporary security needs, we can typically mobilize qualified officers within 24 hours of your request. For ongoing contract programs, deployment follows an agreed schedule tailored to your site’s requirements.
Pricing depends on several factors: number of officers required, shift hours and coverage pattern, service type (armed vs unarmed), site complexity, and contract duration.
