Signifyd is a commerce fraud protection platform that combines ML fraud detection with a financial guarantee — when Signifyd approves an order and the order later turns out to be fraudulent, Signifyd reimburses the merchant for the chargeback. This guaranteed fraud protection model aligns Signifyd's incentives with merchants: Signifyd absorbs the cost of fraud on approved orders.
The Signifyd Commerce Network is the ML foundation — a consortium of merchant transaction data from thousands of global retailers providing the behavioural patterns needed to distinguish legitimate customers from fraudsters at order approval speed. Network effects make the model more accurate as more merchants share anonymised signals.
ML order decisioning analyses hundreds of signals per order — device fingerprinting, IP geolocation, email and payment history, shipping behaviour, and order characteristics — producing a real-time fraud score and approval decision in milliseconds. Chargeback rates for Signifyd-approved orders are dramatically lower than industry averages.
Account takeover protection monitors login and account activity for behaviour indicating compromised credentials — detecting account takeover attempts before fraudulent orders are placed.
Abuse prevention extends beyond fraud to policy abuse — detecting coupon stacking, return fraud, and loyalty programme abuse from customers who exploit promotions rather than commit traditional payment fraud.
Signifyd AI runs as ml platform software built around data workflows. Users typically start with a prompt, upload, or connected data source, and the underlying model handles the heavy lifting before returning a result you can refine or export. It's available on web and api.
