Detect proxies, VPNs, and TOR connections using real-time IP reputation data. Enrich any IP address lookup with risk, geo-location, connection type, and more to improve fraud detection and prevent advanced cybercrime including click fraud, account takeover, and other high-risk behaviors.

VPN & proxy detection API  have become increasingly sophisticated within the past few years, utilizing proxy and VPN connections to commit online scams and other illegal activities. Companies need a way to identify these types of connections so they can flag them as suspicious for further investigation and block access to their services, websites, or networks.

One way is to use a VPN & proxy detection API, such as the IPQS solution that includes a database of proxies, VPN providers, and other anonymizers with daily updates. This can be incorporated into the front-end of fraud prevention measures, to help reduce risk and protect user privacy without interrupting legitimate business operations or spooking real users.

Anonymous Traffic Detection API: Safeguard Against Suspicious Online Activity

For example, a sports streaming service can use this data to geo-block IP addresses from regions where piracy of regional events is often committed. Then, when a new unauthorized connection attempts to access their system, the API can trigger an alert or additional authentication steps based on this information to better protect against unauthorized activity.

For ad tech, this data can also improve targeting by ensuring that ads are served to a user based on their actual location, rather than the apparent location of a VPN server. This can help protect against fraudulent clicks and other fraud associated with the practice of using VPNs to hide their true identity while clicking on advertising.
