The Problem

The business problem
we had to solve.

The client needed to reduce manual review pressure, detect new fraud patterns earlier and keep decision latency low enough for customer-facing financial workflows.

The solution WebSenor delivered

WebSenor built a modular scoring service with event ingestion, model-assisted risk bands, rules fallback, reviewer queues, audit trails and dashboards for operations and leadership.
