Introduction
Network analysis allows insurers to identify patterns of behaviour that extend beyond individual claims or customers. Fraud networks often reuse people, addresses, devices, or suppliers, making relationship-based analysis essential for uncovering organised activity.
As fraud becomes more coordinated, network analysis has become a core detection capability.
What Network Analysis Is
Network analysis examines how entities are connected over time and across events. In insurance, these entities may include:
- Claimants
- Policies
- Vehicles
- Devices
- Repairers or suppliers
Connections between these entities can reveal shared behaviour that indicates elevated risk.
Why Network Analysis Matters
Reviewing claims in isolation often hides repeat or organised fraud. Network analysis enables insurers to:
- Identify fraud rings
- Detect repeat offenders
- Surface hidden connections
- Prioritise high-impact investigations
This broader view significantly improves detection effectiveness.
Network Analysis in Practice
Modern network analysis platforms use graph-based models and visualisation tools to help investigators explore relationships intuitively. Combined with entity resolution, these tools ensure networks are accurate and meaningful.
Investigators can quickly move from a single claim to the wider network context.
From Detection to Prevention
Beyond investigation, network insights support prevention by identifying shared infrastructure, common suppliers, or recurring patterns. Addressing these root causes helps reduce future fraud exposure.
