Case Study: MONIX cuts fraud by 57% and lowers CAC with AppsFlyer Fraud Protection

How MONIX reduced fraud by 57% and cut CAC by 13.4%

MONIX, a Bangkok-based fintech company behind the FINNIX AI lending app, was scaling user acquisition while facing growing mobile ad fraud risks such as click injection, install hijacking, and bot traffic. These issues were inflating costs, distorting campaign performance, and making it difficult for the team to measure ROI accurately or expand confidently across ad networks.

To address this, MONIX implemented AppsFlyer’s fraud protection solution, including Protect360, to detect and block fraudulent attributions in real time. With AppsFlyer, MONIX reduced its fraud rate by 57% and lowered CAC by 13.4%, while also improving data integrity, strengthening ad network relationships, and enabling more confident expansion into new UA channels.
