Case Study: Major Digital Financial Services Company eliminates credential stuffing and 6.4M token replay attacks while reducing false positives with Arkose Labs

Financial Trading Platform Stops Attackers, Reduces False Positives with Arkose Labs

Major Digital Financial Services Company, a leading digital trading platform serving millions of customers, was hit by a surge of automated threats as traffic grew 20x: large-scale account takeover (ATO) attempts, fake account creations, token replay attacks, and overwhelmed security teams that produced high false positive/negative rates. To address this, the company engaged Arkose Labs and its platform for web and mobile protection.

Arkose Labs deployed its detection engine across the client's web and mobile flows, applying risk-based automated friction, token validation, and ongoing tuning to classify traffic and harden APIs. Arkose Labs’ solution eliminated credential stuffing, stopped 6.4 million token replay attacks in the first weeks, maintained good-user throughput, reduced identity fraud and related costs, and delivered actionable visibility for continued adaptation to evolving attacks.
