Case Study: Aargauische Kantonalbank cuts false positives by 90% and boosts fraud detection with NetGuardians' NG|Screener

Aargauische Kantonalbank - Customer Case Study

Aargauische Kantonalbank, a Swiss regional bank with 31 branches and nearly CHF23bn in assets, needed a faster, simpler fraud-mitigation system that could analyze high-volume payments (around 120,000 transactions on busy days) and integrate with its Avaloq core banking platform. After reviewing options, the bank evaluated NetGuardians’ machine-learning solution NG|Screener to replace its complex rule-based, partly in‑house process.

NetGuardians implemented NG|Screener (with Swisscom as implementation partner), integrating it into AKB’s payment channels and Avaloq; the rollout completed in late 2018. Within seven months the system analyzed more than five million transactions, blocked ten times fewer legitimate payments while improving fraud detection, and delivered a 90% reduction in false positives versus the previous controls—resulting in a scalable, user‑friendly solution that met Aargauische Kantonalbank’s requirements.
