Fraudsters use proxies to conceal their true IP address when making online transactions, which makes them highly valuable targets for detection tools. Many services offer a proxy detection feature that uses ping tests and other criteria to determine whether an IP is behind a tunnel. While this may help detect proxies, it can miss some, and is often time-consuming.

Proxy Detection with transaction scoring is to look for patterns in the HTTP headers. For example, a large geographical delay in response times could be a clear indicator that a connection is not direct. This kind of info is easily accessible through a proxy detection API, and it can be used to inform rules engines and fraud models.

Some services also provide additional contextual information about the proxy. This can include details about the type of proxy (cache, corporate, residential), its ISP, and its history of usage. These are additional points that can be added to an overall IP score and can improve the accuracy of ecommerce fraud filters.

AbstractAPI’s real-time Proxy Detection API gives websites and apps access to this risk data, including an instant proxy check with a range of options for detecting proxies, VPNs, and TOR connections. This API is ideal for use in a wide variety of industries, from verification during login to streamlining the process of verifying customers’ identity during purchase. It’s available as a simple JSON or XML response, and it can be triggered by user actions such as registrations, clicks, transactions, and more.
