Case Study: Major Europe Operating Bank achieves 71% detection of social engineering fraud on its mobile app with Nethone

How we decreased fraud rates for a major bank operating in Europe & Asia

Major Europe Operating Bank, a major bank operating in Europe and Asia, faced rising social engineering attacks on its mobile banking app and was unhappy with its rules‑based anti‑fraud setup. The bank required a fast (≤500 ms) and fully compliant solution that respected strict national data‑localization and privacy laws, so it engaged Nethone and its advanced fraud prevention solution.

Nethone deployed an ML‑driven system combining digital fingerprinting (5,000+ signals) and behavioral biometrics, integrated to meet GDPR and national localization requirements while processing traffic in the EU. In a 500k‑user PoC (80M monthly transactions) Nethone detected 71% of fraud attempts, delivered a 500 ms median response time, recorded just 0.026% false positives and demonstrated potential transaction rejection as low as 0.028%, blocking numerous high‑value attacks and surfacing real‑time insights via its control panel and API.
