A data center under construction must stop tailgating at its employee entrance. The architect proposes a small vestibule with two electronically interlocked doors: the second door will not unlock until the first has closed and the user's badge is validated. Which physical access control should the organization deploy to meet this requirement?
A mantrap-also called an access control vestibule-uses two interlocking doors that operate sequentially. An authorized individual badges at the outer door; that door must close before the inner door unlocks, ensuring only one person can enter and preventing tailgating or piggybacking. Turnstiles, CCTV, or single card readers do not provide the same single-person verification or door interlock capability.
