The challenge
What organisations face
Rules-based fraud engines struggle with instant payments, synthetic identities and fast-moving attack patterns. Static thresholds generate high false-positive volumes, frustrating genuine customers and overloading investigation teams, while new fraud typologies slip through until rules are manually rewritten. Risk committees also need to understand why a transaction was blocked before trusting machine learning.
The solution
What VulcanTech engineers
VulcanTech would engineer an event-streaming pipeline that enriches each transaction with device, behavioural and network features, scores it against gradient-boosted and graph-based models, and returns a decision within the payment window. Reason codes accompany every score. A feature store, champion-challenger deployment, drift monitoring and an analyst case console complete the platform, with full decision logging for audit.
Expected outcomes
What changes for the business
- Fewer genuine customers declined at the point of payment
- Analyst effort focused on the highest-risk alerts
- Explainable decisions ready for model risk review
