Case Study: Cdiscount reduces account takeovers and payment fraud with LexisNexis Risk Solutions (ThreatMetrix)

ThreatMetrix Helps Cdiscount Detect Fraudulent Activity

Cdiscount, France’s leading e‑commerce retailer and marketplace with nearly 9 million customers and a catalog of some 40 million products, faced rising fraud as online transactions grew: account takeovers, payments with stolen card credentials, automated bot attacks and the risk of driving good customers away with excessive friction. The company needed to protect saved payment data, stop fraud without blocking legitimate shoppers, and reduce chargebacks and manual reviews.

Cdiscount deployed LexisNexis ThreatMetrix digital identity intelligence—combining device, location and behavioral signals (SmartID, TrueIP, mobile SDKs, Champion/Challenger testing and professional services)—to build a persistent digital identity and flag anomalous activity in near real time. The result was a significant reduction in account takeovers and payment fraud (detecting 95% of potential losses), fewer 3‑D Secure step‑ups, targeted blocking of bot attacks, and greater confidence to accept more legitimate orders and offer split‑payment options only to trusted customers.
