Relationship Graphing
An AI technique that maps and analyzes normal communication patterns and business relationships to detect anomalies indicative of fraud.
Overview
To catch advanced Business Email Compromise (BEC), you must know what 'normal' looks like. Relationship Graphing utilizes AI to continuously learn who talks to whom, what topics they discuss, and what tone they use. If an employee suddenly receives an urgent wire transfer request from the 'CEO'—but they have never communicated directly before, or the sender is using a new device or unusual language—the relationship graph flags it as an anomaly. PhiShark integrates this behavioral baseline with NLP to instantly validate complex impersonation attempts.
