Tailgating is a physical security breach that occurs when an unauthorized person follows an authorized employee into a restricted area—often without the employee even noticing. It’s a form of social engineering, exploiting human error and lack of awareness to bypass access control systems. This kind of attack can lead to major consequences, including data theft, system sabotage, or reputational harm. Fortunately, businesses can defend against tailgating by implementing stronger physical security policies, technologies like biometric authentication, and regular security awareness training.
Tailgating is a social engineering attack that hackers use to gain unauthorized access to password-protected or off-limits, software-protected physical locations. An attacker closely follows an authorized employee into a secured area—exploiting human error and lapses in security protocols.
Organizations at risk include:
Tailgating attackers often try to “blend in” by engaging employees in conversation or mimicking their behavior. They may wait for someone to open a door, then quickly slip inside—causing a physical security breach that can lead to data theft, sabotage, or reputational damage.
Tailgating is sometimes confused with piggybacking, but there is a key difference:
Both fall under the umbrella of social engineering and present serious risks to company security.
Let’s say a contractor shows up wearing a fake badge and carrying a coffee tray. They wait near a secure door and strike up friendly conversation with an employee walking in. As the employee swipes their badge and opens the door, the contractor quickly follows—impersonating a legitimate visitor. No one questions it.
In this case, the attacker bypassed access control measures without hacking any systems. The breach occurred because of human error, not a technical flaw. These situations highlight the importance of surveillance systems and proper security awareness training.
Social engineering refers to manipulating people into compromising security measures. It leverages psychological tactics to trick employees into giving away sensitive data, granting access, or making unsafe decisions. These attacks happen online, in-person, or through phone calls and can be used for:
A robust anti-tailgating strategy includes:
Train employees to challenge unfamiliar individuals, never hold the door open for strangers, and immediately report suspicious activity.
One overlooked risk of tailgating? It often goes hand-in-hand with credential sprawl, where employees share login access or physical keys. Implement a least-privilege model and regularly audit access levels to minimize exposure.
