What is Tailgating?

Tailgating in cyber security is a physical security breach where an unauthorized person enters a restricted area by closely following someone who is allowed to enter.

It is a social engineering risk because it exploits politeness, distraction, busy entry points, or weak physical security controls rather than a software vulnerability. In enterprise environments, cyber security tailgating can expose devices, servers, documents, networks, and employee workstations to unauthorized access.

How does it work?

A tailgating attempt usually happens at a door, lobby, elevator, turnstile, loading bay, or shared office entrance. The attacker may walk in behind an employee, carry boxes to appear harmless, pretend to have forgotten a badge, or blend into a group during peak hours.

Once inside, the risk moves beyond the doorway. The person may access unattended devices, plug into a network port, view confidential information, steal hardware, or gather details for a later attack.

Tailgating vs piggybacking

Tailgating usually means the authorized person does not knowingly allow the intruder in. Piggybacking is often used when the authorized person knowingly or carelessly permits another person to enter without proper verification.

Both risks require layered controls. Access controls, security awareness, visitor processes, badge checks, surveillance, and locked workstations all reduce cyber security tailgating exposure.

How Hexnode supports tailgating prevention

Hexnode supports tailgating prevention by helping organizations reduce the endpoint impact of unauthorized physical access. Through UEM, teams can enforce screen lock rules, encryption, password policies, application restrictions, USB controls, compliance checks, and remote actions across managed devices.

Hexnode also helps with endpoint security audit workflows by giving IT teams visibility into device compliance status, policy enforcement, installed applications, patch posture, and risky devices that may need immediate remediation.

When should organizations use it?

Organizations should address cyber security tailgating when employees, contractors, visitors, vendors, or shared-office users can physically access areas where business systems or sensitive data are present.

It is especially important for regulated industries, hybrid workplaces, data centers, healthcare facilities, schools, warehouses, and offices with many visitors. A good program combines employee training with physical access control and endpoint safeguards.
