Detect VPN PHP – How to Detect VPN and Proxy Usage

detect VPN PHP

VPNs are widely used for privacy and security purposes. However, they can also be abused for fraudulent activities like identity theft and credit card fraud. As a result, it is critical for online businesses to detect VPN and proxy usage to minimize fraud risk.

Using detect VPN PHP is an effective way to help identify visitors and users who may be hiding their true IP addresses. This method uses an IP2Proxy database or Web service to look up the proxy status of a given visitor’s IP and return an indication of whether it is likely that they are using a proxy server.

How to Continuously Detect VPNs with PHP

A disadvantage of this method is that it only returns the proxy’s IP, not the visitor’s. This means that it will not be able to filter visitors based on their true location. However, it can be combined with other methods for more robust detection of suspicious activity, such as IP blocklist matching and browser bot detection.

Another potential issue is that this detection will only work for IP addresses that are known to be associated with proxies and VPNs. This is because these connections will hide the HTTP_X_FORWARDED_FOR and HTTP_CLIENT_IP headers, which would otherwise indicate that a visitor is using a proxy. As a result, it is important to test this method with real traffic on your own website before implementing it in production. The simplest way to do this is by requesting the location of the user’s server and checking that the time zone of their reported timezone matches with the time zone of the region corresponding to the IP geolocation.
