Advanced Proxy
Detection API Service

Online frauders hide their IP addresses through Proxies, Tor nodes, & VPN connections to conceal their location and true identity details. IPQ's free proxy detection service can prevent frauders with spoofed IP addresses from accessing critical pages of your site such as purchasing a product that could result in an expensive chargeback, creating fraudulent accounts, advertising click fraud, evading country specific filters, or performing malicious actions on other conversion points.

IPQ's proxy detection API is the most comprehensive tool online to identify IP address connections with a high probability of malicious intent. This includes IP addresses that are open proxies, anonymous proxies, Tor nodes, VPNs, hosting providers, spammers, criminal networks, malware & spyware, botnets, and other undesirable connections that are highly inclined to engage in malicious activity.

How Does this Proxy Detection Service Work?

IPQ's Proxy Detection service analyzes the IP address and other forensic factors of the connection to determine if the user is hiding behind a spoofed IP or is attempting to frequently change their device. We actively maintain an IP addresses threat blacklist that is updated hourly to include the latest emerging threats from hijacked computers and open proxies to other sources of malicious IPs. We also remove IP addresses from our database that are no longer threats to reduce the chance of a false-positive result.
