Tailgating Explained
Tailgating (also known as piggybacking) is one of the most widespread security breaches affecting businesses today and often goes undetected. Tailgating can be simply described as the passage of unauthorised personnel, either forced or accidental, behind that of an authorised user.
One of the most frequent instances of tailgating occurs when an employee politely holds open a door for a colleague or visitor. This unintentionally creates a security breach by enabling an unauthorised user to access the building or area. Another instance where tailgating can occur is when an oblivious employee allows a door to slowly close behind them, leaving the opportunity for an unauthorised user to enter via the closing door. Tailgating can also happen unintentionally by third parties such as subcontractors propping open a door whilst carrying out works. Tailgating can be a particular problem in multi-tenanted buildings where there are a large number of employees and contractors accessing the building.
Employee training is the most effective way to combat this vulnerability. Other measures to mitigate the risk of tailgating include using security cameras, multi-factor authorization, or requiring duel authentication.
A Security Revolving Door or Security Portal can provide the highest level of anti-tailgating detection, ensuring the user is alone. Security Revolving Doors and Security Portals can also enable sites to operate 24/7 with unmanned access, ensuring only authorised users can gain access day or night.
Speed Gates – Tailgating (piggybacking) detection – the user presents a valid ID card, the gate opens and the user enters the lane. When a second user without a valid ID card enters the lane tailgating is detected. An alarm output is given and the gate closes.
