Device Fingerprinting

Fraudsters often change or mask the information they use when purchasing to pass as a legitimate order. Device fingerprinting allows us to counteract fraud abuse by analyzing hundreds of device and browser data points to uniquely identify and track devices that transact on your site. This allows us to quickly identify and block known bad devices, allowing legitimate orders and customers through. And with over 10 billion tracked devices in our network, we are able to provide superior decision accuracy and fraud protection.
