Deploying the Cortex XDR agent during a Cortex XSIAM proof of value (POV) is important because it provides telemetry for stitching and analytics. The agent collects endpoint data that is essential for detecting and correlating threats, enabling advanced analytics and providing the necessary context to improve incident response and decision-making in the security environment.

The Live terminal capability in Cortex XDR allows the immediate termination of an anomalous process or the entire process tree during the investigation of a security event. This feature helps analysts take swift action to stop potentially malicious activity on the endpoint in real-time.
