Building Security Breach Prevention

Tailgating is a physical security vulnerability where an unauthorized person slips into a restricted area by closely following an authorized employee through an entryway. Attackers rely on normal human courtesy or distraction—such as an employee holding a door open or failing to notice someone right behind them.

Technology can help prevent tailgating attacks by controlling access to sensitive areas and entrances, incorporating video surveillance, and enabling digital visitor identification. Door Detective is an anti-tailgating device that eliminates the blind spot in traditional access control systems by ensuring that only one authorized person can pass through an open door per credential, in the approved direction.
