IPQS’ proxy detection API is the Internet’s leading source for proxy & VPN connection reputation scoring and data. It identifies high risk connections likely to engage in fraud with the greatest accuracy in the industry and offers a variety of additional features for protecting your website from malicious traffic.
Our IPQS Proxy Detection API is used by gaming communities, e-commerce websites, research universities & institutions, law enforcement, and large financial institutions around the world. The API serves millions of requests per week and is growing as more people find it useful in protecting their online infrastructure.
Identify IP addresses that are most likely to be a bot, proxy, VPN, or TOR node with over 40% greater detection rates than similar services and less false-positives!
Proxies / VPNs allow users to bypass geo restrictions for VOD and OTT content. They also provide an opportunity for fraudulent activity, including creating duplicate accounts and posting spam.
Fraudsters often use proxies to hide their identity and engage in malicious activity while still accessing websites. This is especially true for mobile proxies, which simulate a phone or tablet’s IP address without necessarily needing the device to connect.
In addition, a proxy may be used to access an account on a social media platform or gaming community. This can make it difficult for sites to detect fraud and track user behavior.
A common technique is to compare a browser’s user agent with the IP address of the target website. This can be done by using a WebRTC check or measuring latency on the TCP/IP handshake between the browser and server.
Another way to detect a proxy is by checking if the IP is listed on any blacklists or blocking lists. These aren’t always accurate, but they can be useful for detecting suspicious patterns in a given region.
Unlike many other services, our proxy detection API uses a range of different techniques to identify proxies and VPNs. These include DNS leaks, HTTP header requests, and more.
One of the most common methods for identifying proxies is by comparing the IP time zone against the web page’s location. This can be particularly useful in a country where the proxy is located.
A proxy connection may also leave open ports, which can be a red flag. This is especially true for mobile proxies, since they typically don’t have an internal firewall.
This can be a strong indicator that a user is connecting from a remote location, such as a third country.
Similarly, it can be used to identify a DNS leak, which is a common security and privacy issue for ISPs. This allows them to track the entire internet’s traffic without a user’s knowledge.
Our proxy detection service is designed to be fast, efficient, and accurate. It uses machine learning & probability theory techniques to infer the likelihood of an IP being a bad proxy or VPN with dynamic checks on large datasets. This system is updated regularly to ensure the most accurate results.
