At first glance holding a door for someone is an innocent act because it is a matter of courtesy. However, this event may have grave consequences for an organization from theft of equipment or intellectual property to harassment or a violent crime.
Organizations use the following strategies to mitigate tailgating:
- Conducting security training for employees
- Implementing anti-tailgating devices which limit entry to a single person at a time (such as mechanical or optical turnstiles, revolving doors, photosensors, mantraps, etc.)
- Video surveillance with facial recognition technology
- ID verification at entrance
