When fraudsters spoof their connection details to commit fraud or evade compliance regulations, it’s important for businesses to be able to detect that they are using a VPN. This allows you to block access to your content, protect data and improve security.

VPN proxy detector is the process of analyzing an IP address to determine whether it might be connecting through a proxy or VPN service. There are a variety of ways to do this, from the use of built-in browser tools to third-party services such as Greip and IPQS. The most accurate methods of VPN detection are those that can identify multiple factors, such as a time zone mismatch between the browser and device, network latency, or an operating system mismatch.

Number Verification Online: Ensure Accuracy and Validity

Some popular online services and databases provide VPN detection by checking an IP address against a database of known proxies and VPN servers. These include MaxMind GeoIP, ipapi, IP2Location and others. They typically return a probabilistic value between 0 and 1 of how likely an IP address is a proxy or VPN, based on a combination of dynamic checks with large datasets parsed by machine learning & probability theory.

Our VPN detection API ensures enterprise-grade accuracy by leveraging machine learning algorithms to recognize signatures aligning with private VPN servers, residential proxies, TOR exit nodes, and similar infrastructure. Combined with our IP reputation scoring, this enables web sites to block suspicious traffic and reduce risk, as well as deliver better experiences to customers while meeting regulatory compliance obligations.
