IPQS – The Best Proxy Detection Web Service
Using a IP proxy detection web service is hidden, meaning websites cannot determine where you are located. This is particularly dangerous for e-commerce websites where fraudsters can hide their real location to commit various types of fraudulent activity, such as fraud chargebacks, fake account registrations or advertising click fraud.
Some online services offer a free Proxy detection web service, which checks the user’s IP against a list of known proxies and warns the user that they may be using a proxy. This method of checking proxies is useful, but it’s not foolproof and there are multiple ways to use a proxy without getting caught, including using VPNs and mobile data network connections.
Benefits of IP Proxy Detection Web Services
The best proxy detection methods are based on analyzing HTTP headers and other signals. These can reveal clues such as a mismatched OS, which is usually caused by a proxy or a mobile device. One example is the open source satori project, which fingerprints a device by examining the contents of TCP/IP packets sent and received from the web browser to detect if the browser is using a proxy.
IPQS’s proxy detection API uses proprietary honeypots & traps, blacklists, forensic analysis and client feedback to provide the most advanced proxy detection in the industry with unrivaled accuracy rates for residential proxies, private proxies, Tor nodes, VPN providers, datacenter proxies, botnets and similar risky shared connections abused by the worst fraudsters online. The API can score users beyond just their IP address for the best performance, and also scores based on device information and transaction history to prevent false-positives that are common with other proxy detection solutions.
