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 IP address forensic analysis API is the most comprehensive tool online to identify IP address connections with a high probability of malicious intent.

How Does this Service Work?
Our system 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. Our blacklist of IP addresses is updated hourly to include the latest emerging threats from hijacked computers and open proxies to and 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.
