Fraudsters use proxies to hide their true location, which can result in geo-blocking, account takeover and other forms of fraud. Combining fingerprinting with proxy detection ensures that user authentication is always based on an actual device connected to the Internet, rather than a masked connection. This also helps prevent click fraud, ad fraud and other types of bot activity that can eat up advertising budgets or erode the quality of a user experience.
The Proxy Detection integration overview detects anonymous proxy connections to help you stop attacks on your website. The service analyzes the request header and examines corroborating information, such as browser type and version, OS and other factors. The service also scans incoming connections to look for clues, such as DNS leaks or large response times.
Proxy Detection Integration Overview: Step-by-Step Guide
The Proxy Detection feature is integrated with the Fingerprint JS agent, which enables precise visitor identification without using cookies. This enhances security and fortifies the Fingerprint JS against interference from many ad blockers, which often obfuscate or compress JavaScript code to obscure their activities.
The Fingerprint JS agent can be configured to send Proxy Detection data in the header of every request. This can be used with risk scoring to identify patterns and flag suspicious behavior that can be further investigated by other security layers. For example, combining fingerprinting with proxy detection can help prevent multi-accounting and bonus abuse in online gaming, where users might create multiple accounts to avoid geo-restrictions and claim bonuses.
