Free VPN usage is rising across the UK, mostly driven by recent regulations limiting access to certain online content, and will most likely become even more prevalent in 2027 with further regulations on the horizon. However, using a free VPN introduces real cyber security risks when it carries over into the workplace.
In business, using a free VPN is not a harmless workaround. It affects how security tools operate and can expose your company to additional and avoidable risk.
Platforms like Huntress, and other modern cyber solutions rely on spotting unusual behaviour. This includes logins from new locations, unfamiliar IP addresses, and changes in user patterns. These signals help identify potential attacks early.
When a user connects through a VPN, their location can appear to change instantly. A user based in Burnley might suddenly appear to be logging in from another country. From a security standpoint, this triggers an alert, as it should.
The issue begins when this behaviour becomes normal, particularly with free VPN services.
If users regularly connect through free VPNs, security tools start generating a high volume of alerts. Over time, this leads to alert fatigue. Security teams are faced with repeated warnings that turn out to be harmless, making it harder to identify genuine threats that may happen. Think of the Boy Who Cried Wolf story here.
Alert fatigue is not just frustrating. It introduces real risk. Important alerts can be missed, delayed, or ignored. When that happens, real threats are more likely to go undetected.
There is also a loss of visibility. Effective cyber security depends on understanding what normal user behaviour looks like. If free VPNs constantly change how users appear online, that baseline becomes unreliable. Detection tools become less accurate, increasing both false positives and the chance of missed incidents.
The Hidden Risks of Free VPN Services
Free VPNs also introduce far more risks in their own right.
Many free providers fund their service by logging user activity or injecting ads into traffic.
Some send data through insecure or unknown infrastructure. In a business environment, this can expose sensitive data and create serious compliance issues.
There is also a lack of accountability. With free VPNs, there is no contract, no service guarantee, and little to zero transparency around how data is handled. This creates a blind spot for IT teams and can undermine internal security policies.
By contrast, paid VPN providers such as NordVPN are not risk free, but they are more predictable. Their infrastructure and IP ranges are more widely recognised, which can make them easier for security tools to handle and monitor. Even so, unmanaged use of any VPN still creates unwanted challenges.
What UK Businesses Should Do Instead
For UK businesses, the message is clear. The rise in VPN usage may be driven by external factors, but free VPNs introduce avoidable risk into the workplace.
Unmanaged use disrupts monitoring, increases alert noise, reduces visibility, and can expose sensitive company data.
Businesses should have clear policies in place and ensure only approved, trusted VPN solutions are used where necessary. These should be deployed and managed at a company level, not left to individual users.
This keeps monitoring effective, reduces unnecessary noise, and allows security teams to focus on genuine threats.
In cyber security, too many false alarms can be just as dangerous as none at all.
