Why Should I Block Proxies?

Proxies allow a user to mask their IP address and assume a digital identity that is not representative of their true identity. For example, one user in Russia could control thousands of IP addresses in the US, performing malicious actions such as creating fake accounts, submitting user generated SPAM (comments, posts, etc.), and engaging in fraudulent transactions. These actions could look entirely natural and would be difficult to filter from your legitimate users without impacting the user experience. By blocking proxies with IPQS, the process is much more difficult for a fraudster to perform malicious actions and engage in abusive behavior. Instantly improve your user quality and transaction quality by filtering proxies and other connection anonymizers in real-time.

Can IPQS Proxy Detection Block Residential Proxies?

Yes, IPQualityScore's proxy detection service can fully detect residential proxies and stealthy connections that are difficult to distinguish from a legitimate user with a residential connection. With the naked eye, one would never be able to detect a residential proxy. Luckily, IPQS has easy-to-use tools that can detect these risky connections with precision accuracy. Residential proxies are usually the preferred choice for fraudsters when engaging in duplicate account fraud, scraping, payment fraud, and similar types of mischievous activity.

Quick Integration for Blocking Proxies

IPQS provides a simple API that you can use to query if an IP address is a proxy or VPN connection, or if the IP address has been involved in any recent abuse across our network. Additional details such as the browser, user language, and other parameters can also be examined to increase detection rates. Access over 20 data points through our flexible APIs.
