Tailgating is one of the most overlooked security risks faced by businesses today. It might seem harmless at first—a visitor or unauthorised individual slips through the door right behind an employee. But what feels like a moment of politeness can create serious vulnerabilities. Tailgating opens the door to theft, data breaches, and even threats to employee safety.
The good news is there are ways to stop it in its tracks, and the most effective solution lies in the use of security portals. But before we get to that, let’s break down why tailgating happens and what can be done about it.

What Is Tailgating and Why Does It Happen?
Tailgating occurs when someone follows an authorised person into a secure area without permission. It often happens because employees feel awkward denying entry or assume the person behind them has legitimate access.
The issue is particularly concerning in environments where sensitive information or valuable assets are at stake. For UK businesses, complying with regulations like GDPR makes preventing tailgating even more critical. Whether you run an office, a hospital, or a data centre, failing to secure your entrances can lead to serious financial and reputational damage.
Why Is Tailgating a Problem for Businesses?
The consequences of tailgating go far beyond someone wandering into the wrong part of your building. It can lead to:
- Data breaches: An unauthorised person could gain access to confidential files or servers.
- Theft or damage: Equipment, stock, or sensitive assets could be stolen or vandalised.
- Employee safety risks: Tailgating opens the door to potential physical threats.
In short, tailgating is a threat no business can afford to ignore.
What Steps Can Businesses Take to Prevent Tailgating?
1. Educate Employees
It might sound basic, but ensuring employees understand the risks of tailgating is crucial. Simple actions like reminding staff not to hold doors open or asking them to challenge anyone without credentials can make a big difference. Training sessions or even posters near entrances can reinforce these behaviours.
2. Implement Surveillance and Barriers
CCTV cameras are a great first step. Not only do they act as a deterrent, but they also provide valuable evidence if an incident occurs. Physical barriers like turnstiles or speed gates add an extra layer of control, ensuring that only authorised individuals can pass through.
3. Upgrade to Security Portals
For the ultimate protection against tailgating, nothing beats a security portal. These advanced systems ensure that only one person can enter at a time, completely eliminating the risk of tailgating. Let’s look at why they’re the best option.

Why Are Security Portals the Best Solution?
A security portal is more than just a door—it’s an intelligent access control system. With interlocking doors, only one person can pass through at a time, and each entry requires verification, whether through a keycard, PIN, or biometric scan.
Here’s why they’re so effective:
- They stop tailgating entirely: The interlocking mechanism prevents anyone from sneaking through.
- They’re adaptable: Security portals can be customised to suit your building’s layout and aesthetic.
- They integrate advanced tech: From biometrics to real-time monitoring, they provide cutting-edge security.
For businesses in the UK, security portals are particularly useful in environments like corporate offices, data centres, and healthcare facilities, where unauthorised access could have severe consequences.
