Techniques are described herein for clustering network hosts based on their network behavior to create groups of hosts that behave similarly. An anomaly detection model trained on a single group of network hosts is more robust to fluctuations of the behavior of individual hosts when compared to the per host models. When comparing to the group all models that are trained using the behavior of all network hosts, finer anomalies (e.g., stealthy data exfiltration) that would otherwise be hidden may be detected by modelling diversely behaving network hosts.
