Final answer:
Cortex XDR uses the Behavioral analytics engine and the Security analytics engine to process and correlate data for detecting threats.
Step-by-step explanation:
The two engines employed by Cortex XDR to process data that is collected for correlation are the Behavioral analytics engine and the Security analytics engine. The Behavioral analytics engine is responsible for evaluating behaviors in the network and on endpoints to detect anomalies that could indicate a threat. On the other hand, the Security analytics engine focuses on analyzing large volumes of data and applying threat intelligence to identify potential threats. These combined efforts effectively protect against sophisticated attacks by correlating data from various sources and providing a comprehensive security posture.
