Proxy Detection Database

Download The Most Accurate Proxy Detection Database

Anonymized IP addresses such as proxies, Tor exit nodes, & VPN connections enable users to conceal their location and true IP address, making it difficult to accurately extract a user's true identity. The IPQS proxy detection database makes it easy to identify high risk IPs against those used for privacy while browsing online. Unparalleled accuracy provides the most intelligent proxy detection results without impacting genuine users of your audience.

IPQS proxy detection database is the leading IP Reputation data set to easily distinguish riskier IP addresses with a history of fraudulent behavior or a high probability of malicious intent. This includes IP addresses that are open or anonymous proxies, Tor nodes, VPNs, hosting providers & data centers, botnets, residential proxies, and other undesirable shared connections that are highly inclined to engage in unwanted actions.

What are the Benefits of a Proxy Database?

Proxies, VPNs, and Tor connections are the primary enablers of fraudulent traffic. Abusive users, fraudulent clicks, stolen credit cards & chargebacks, duplicate accounts, user generated content SPAM (such as marketplaces, forums & blogs), and similar mischievous behavior is conducted through proxy connections.

Deploying a proxy detection database on-premises immediately allows your software to identify high risk users and transactions. Greatly reduce headaches from fraud and abusive behavior and ensure users are acting in good faith.

The IPQS anonymous IP database accurately captures all types of malicious IP addresses including anonymous proxy servers, VPN providers, datacenter proxies, residential proxies, and other types of web proxies. Confidently deploy VPN detection in addition to identifying the usual proxy types.
