how it works_

One API to block bots across your platform

Man-in-the-Middle attack detection across web and mobile

Identify, differentiate, and prevent automated threats across your platform with Fingerprint. See how our best-in-class bot detection can solve your challenges:

Fingerprint analyzes 100+ device and network signals and assigns a unique visitor ID to every device, letting you tie sessions to the same trusted environment. This helps detect hijacked sessions and block fraud before it affects your users. Our MitM Attack Detection Smart Signal also flags intercepted requests to Fingerprint servers on mobile so you can spot replay attacks.
