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.

HOW IT WORKS_

Prevent iGaming bonus abuse and multi-accounting with Fingerprint

Fingerprint helps you detect and block repeat signups from the same device, even when fraudsters use incognito mode, VPNs, or device resets. Get real-time Smart Signals for VPN detection, bot activity, and abnormal signup velocity — so you can keep bonuses for real players.

Stop multi-accounting for iGaming promotions

Fraudsters create multiple accounts to claim bonuses again and again, draining your promotional budget. Fingerprint helps you spot and block repeat signups from the same device, even if fraudsters use incognito mode, change IP addresses, or reset their device. This keeps your bonuses for real players and makes your promotions more effective.
