Cortex Xpanse provides visibility over remote workforce risks by identifying customer assets on residential networks. This allows organizations to monitor and secure assets that are outside of the traditional corporate network, which is particularly important as more employees work remotely and connect from various locations.

Managed Threat Hunting combines world-class threat intelligence with Cortex XSIAM (Extended Security Intelligence and Automation Management) technology to help identify attackers. This service provides proactive threat hunting capabilities, allowing security teams to detect advanced threats and respond to potential attacks with the help of expert analysts and automated tools.

The best option for providing 24/7 monitoring of Cortex XDR, given that the customer only has staff available during business hours, would be Managed Detection and Response (MDR). MDR services provide continuous monitoring, detection, and response to security incidents, even outside of business hours, by leveraging expert security teams to manage and respond to threats when the customer's internal staff is unavailable.
