A security gate is a physical access control device that prevents unauthorized entry into buildings or restricted areas. Circular or mantrap-style gates allow only one person to pass at a time, effectively preventing tailgating, where an unauthorized person follows an authorized person through a secured entrance. They are commonly installed at server room or sensitive area entrances as a key physical security measure.
