IPinfo’s VPN Detection API Service
VPNs, proxies, Tor, and private relays are commonly used by fraudsters and bad actors to conduct malicious activities such as click fraud, credit card chargebacks, and other forms of fraud. IPinfo’s privacy detection API helps businesses detect these users by identifying connections coming from VPNs and proxies. Not all VPNs or proxy connections are bad — some are used by employees on the go to access their company network from home, for example, or by travelers who want to stay secure on public Wi-Fi.
VPN Detection API Service: Ensuring Your Website Remains Secure
VPN detection is essential for websites that need to ensure their customers’ data is not masked by VPN or proxy connections. There are a number of methods to identify VPNs, from simple ones like comparing the browser timezone with the server’s geographic region to more sophisticated methods such as TCP/IP fingerprinting and DNS lookups.
ipXapi’s VPN detection API service utilizes a unique approach that requires no JavaScript execution and works on live traffic, meaning it does not introduce any friction to the user experience.

This eliminates the need to create a separate list for each individual VPN service and eliminates false positives, which is an important consideration when evaluating a new detection method. The result is a faster and more reliable detection method that provides accurate results and is suitable for a wide range of use cases.…
