When fraudsters access your website through a proxy, they’re masking their true IP address. This allows them to bypass fraud checks that normally prevent repeat fraudulent activities such as account takeovers or card testing. Detecting the use of a proxy in an order can help merchants understand whether an individual is engaging in high-risk behavior and flag the order as suspicious.
Detect anonymous proxies the use of proxies requires sophisticated technology that analyzes an entire order and its header information. There are a number of proxy detection solutions that work to identify if an IP address is using a proxy by comparing the incoming IP to lists of known proxies and VPNs. Some of these services also compare the IP to the country and state where the device is located, in addition to looking for common obfuscation techniques such as base64 encoding.
iPrism’s solution provides an in-depth look at the world of anonymous proxies and how they operate. Rather than relying on a static list of proxies and VPNs, iPrism’s solution proactively identifies an anonymous proxy through its unique architecture which examines the incoming HTTP request context and focuses on what’s missing from that compared to a typical web server. In addition, iPrism uses real-time methods to detect proxy settings and automatic anonymous proxy detection to provide a multi-layered approach for defending against attempts at circumventing network Internet security via browser-based proxies. This reduces the amount of manual effort required by your IT team to monitor and block proxies.
