The Problem

Cookies expire in 7 days. IPs rotate every session. Fingerprints last months.

Modern fraud prevention relies on tools designed for a different era. Cookie-based identification breaks the moment users clear their browser or switch to incognito mode. IP blocking is bypassed by any VPN. Fraud rings know every rule in your stack — and route around them automatically. Fingerprint builds persistent, hardware-level device IDs that survive cookie clears, IP changes, browser resets, and incognito mode. The same visitor profile, regardless of how they try to hide.

Built for security teams. Ready in an afternoon.
