A ACI Worldwide Case Study
TEB, one of Turkey’s largest banks after its merger with Fortis Turkey, faced a growing and increasingly sophisticated fraud threat across cards, POS, ATM, internet and telephone channels while relying on disparate tools that couldn’t provide a single, fast view of suspicious activity. To consolidate and modernize its fraud defenses, TEB selected ACI Worldwide’s ACI Proactive Risk Manager™.
ACI Worldwide deployed Proactive Risk Manager across all major payment channels and enabled bespoke extensions — real‑time card blocking with SMS/IVR callbacks, integrated monitoring of call‑center and online transactions, and rapid rule‑based detection — giving TEB a consolidated, flexible fraud platform. The ACI Worldwide solution helped TEB detect more than 92% of card fraud and protect over €3.7 million in transactions, establishing one of Turkey’s most advanced fraud‑fighting capabilities.
