Pro Tools

Browser Fingerprinting

Our fingerprinting approach is the most advanced in the market and employs many cutting-edge methods of browser identification.

Geolocation

Every identification API request will provide the geolocation of the current visitor, including geoposition, city, country, timezone and ISP information.

Bot Detection

Our bot probability value will tell you the likelihood of a current visitor being a programmed headless agent to help identify bot traffic on your site.

Anonymous User Identification

Every visitor to your website is assigned a permanent visitorID that can be used to identify visitors trying to change their identity via proxies or other techniques.

Incognito Mode Detection

FingerprintJS Pro tracks whether visitors are using incognito mode, and can accurately identify users across incognito browsing sessions.

API & Webhooks

In addition to browser fingerprinting, FingerprintJS Pro's server-side API processes and analyzes vast amounts of data, searching for patterns and re-occurrences of fraudulent activity.
