Tailgating occurs when someone enters a controlled area without completing the intended access process, often by following an authorized person.
At a glance
- Access control is a recognized security function involving movement of people and vehicles.
- The property should define who is authorized and how visitors are verified.
- Security communication should remain professional when stopping or questioning someone at an entrance.
What this means in practice
The official rules establish a baseline, but a workable security assignment still needs property-specific decisions. The client and provider should turn general requirements into clear instructions about what is checked, who can authorize exceptions, what must be documented and when another authority takes over.
Questions to confirm
- Does the property require every person to badge or sign in?
- How should staff respond when a door is held open?
- Is the entrance design creating repeated confusion?
Picture this at your property
An employee badges into a restricted office and holds the door for someone they assume is a coworker. A clear site rule and polite verification process can address the gap without treating every mistake as hostile behaviour.
The value of the example is the decision process: identify what is known, what remains uncertain, who has authority, and what information should be preserved for follow-up.
Practical takeaway
The strongest security process is usually the one that makes responsibilities, observations and escalation clear. That creates a service that can be understood and reviewed without overstating what security can guarantee.
