Meridian Bank (SEA) engaged VFACE to modernise its fraud detection stack. The existing system relied on static rule sets authored in 2017, producing over 1,200 false positives per day. VFACE deployed an IBM Watson-backed anomaly detection pipeline that learns from transaction patterns in real time, integrated with the bank's core banking system via a low-latency API layer. The model was trained on 36 months of labelled transaction history and validated against a held-out dataset before promotion to production.
