Case Study: OLX achieves 10x more accurate fraud detection with SHIELD

OLX Sets a New Standard in Privacy-Secure Fraud Prevention with 10x More Accuracy

OLX, Brazil’s largest marketplace for consumer goods, vehicles, and real estate, needed a way to stop fraud in real time without adding friction for legitimate users or collecting sensitive identity data. To address this challenge, OLX partnered with SHIELD and its device-first fraud intelligence platform, including SHIELD Device ID and fraud intelligence signals.

With SHIELD embedded, OLX strengthened its fraud prevention with device-level detection that identified fake accounts, bots, emulators, and coordinated fraud rings while preserving user privacy. The results included 10x more accurate fraud detection, 99.8% of fake accounts blocked in real time, and 100% compliance with privacy regulations, along with lower fraud losses and improved user trust.
