Challenge

Fraudsters have moved beyond simple stolen cards; they now use complex networks of synthetic identities and circular transactions. The client's existing systems lacked the "social" context of transactions.

The challenge was to analyze trillion-scale relationship graphs in real-time.

The outdated surveillance infrastructure resulted in critical vulnerabilities:

  • High false-positive rates causing customer friction.
  • Inability to detect networked or circular fraud patterns.
  • Legacy systems unable to handle sub-15ms latency requirements.
  • Massive operational costs for manual fraud investigation.

The organization needed a paradigm shift from transactional analysis to relational intelligence.

The Solution

Real-time Graph-AI Surveillance

WebbyButter built a custom Graph-based AI surveillance layer that sits directly on the client's transaction stream. By mapping every transaction to a massive, real-time relationship graph, the system can identify suspicious "clusters" and anomaly patterns.
