ShieldLabs is fraud detection and prevention with enterprise-level functionality and no enterprise pricing. Find risky users under any masking, stop multi-accounting, account sharing and takeovers, and score your traffic quality.
A JS snippet collects 300+ device and network signals and cross-checks them, with 99.9% identification accuracy and 99.9% risk signal detection accuracy. Shortly after a visit, ShieldLabs delivers a risk score from 0 to 100 and the named risk signals behind it over webhooks and the API. Multi-accounting, account sharing, account takeover and impossible travel are detected out of the box, each at medium or high confidence, with bot and AI traffic detection alongside.
