Case Study: Logzz reduces chargebacks and fraud with SHIELD

Eliminating Fraud and Reducing Chargebacks in the Cash on Delivery Marketplace

Logzz, Brazil’s first digital Cash on Delivery marketplace, was facing rapid growth alongside rising fraud risks, including fake account creation, fraudulent purchases, and increasing chargebacks. To better protect its ecosystem of producers, affiliates, and couriers, Logzz turned to SHIELD and its Device Intelligence solution.

By implementing SHIELD’s device-first fraud intelligence, Logzz was able to detect risky devices and block suspicious logins before transactions were approved. SHIELD helped Logzz cut chargeback rates by 92%, reduce devices linked to fake accounts by 97%, and protect millions of purchases, restoring trust across the marketplace.
