Core Network Insight is an automated breach defense system that empowers security teams to identify infected devices with certainty, address threats faster by prioritizing high-risk devices, and block active infections. It monitors network traffic to automatically discover advanced threats, verify which devices have been breached, and assign a risk level to each infected device in order to contain threats instead of simply chasing alerts. Network Insight uses multiple techniques over time, such as understanding network behavior and applying threat intelligence, to produce actionable intelligence on breaches with more certainty than relying on any single detection method.
