Advanced Proxy
Detection API Service

Block Proxies & VPNs with the Best Proxy Detection Tools!

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 and creating headaches such as credit card fraud & chargebacks, fraudulent accounts, advertising click fraud, evading country specific filters, scraping sensitive content, abusive comments and SPAM, affiliate marketing fraud, or performing other types of nefarious actions.

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, residential proxies, and other undesirable connections that are highly inclined to engage in malicious activity.

How Does Our Proxy Detection Service Work?

IPQ's proxy detection service can be queried via an API lookup or through our user dashboard to instantly reduce fraud. The IP address and other forensic factors of the connection are analyzed to determine if the user is hiding behind a spoofed IP, tunneled connection, or is attempting to frequently change their device. Over 20 data points, including proxy status • recent abuse • organization • detailed geo data • fraud score • VPN connection • Tor connection • crawler status, and similar details are returned for each proxy API lookup to provide a detailed analysis for each request. IPQ's threat blacklists are actively maintained and updated in real-time to include the latest emerging threats from hijacked computers, open proxies, residential botnets, & other sources of high risk connections. We also remove IP addresses from our database that are no longer threats to reduce the chance of a false-positive result which is a significant issue for other proxy detection service providers and can greatly limit legitimate traffic.

Fraud Scoring and Proactive Fraud Prevention

The anti-fraud industry has different approaches for dealing with fraud. IPQ believes that the best way to manage fraud is to completely prevent it from happening in the first place as this saves time and has a higher success rate in reducing fraud overall. Rather than review post-analysis reports or receive notifications after fraud has been committed, IPQualityScore can prevent fraud and high risk behavior in real-time. This approach allows you to block proxy and VPN connections and adjust scoring settings in real-time. All of our anti-fraud tools also return a real-time "fraud score" so that users with a fraud score in a high risk threshold are detected and flagged for review or redirected away from critical parts of a site like a registration or payment page, comments section, click funnel, etc. This results in fewer problems with managing users, clients, & advertisers. Let IPQ automate your quality control and greatly reduce time spent on cleaning up abuse such as manually detecting duplicate users, clearing SPAM, blocking high risk users, and in general less headaches so you can focus on more productive tasks.

IPQ's Proxy Detection API can accept additional information to enhance the "fraud score" accuracy. We recommend passing the user agent (browser), user language, and additional details found on the user dashboard into each API request. Full transaction info including billing, shipping, and credit card data can optionally be scored as well. This gives us greater insight than just examining an IP address so we can give you the most accurate prediction of fraudulent behavior for each lookup. IPQ's fraud scoring combined with the status of the lookup as a proxy connection, VPN connection, or Tor connection is a proven solution to preventing fraud and abuse.
