What is Sift Science Device Fingerprinting?

Using a new fake account, username, or email address for each fraud attack is as easy as pie. Using a different device? Not so simple. That's why we fingerprint and track all devices used across our global customer network.

Sift Science Device Fingerprinting uniquely identifies and tracks every device that accesses your site. Once you know which devices are used by the bad guys, blocking them is a piece of cake. Get started in minutes; you'll be employee of the month before your free trial even expires.
