Which node enables Cisco ISE to share contextual information on a device with Cisco Stealthwatch?

The Monitoring and Troubleshooting Node (MNT) primarily focuses on collecting and storing operational logs and monitoring data for auditing and troubleshooting within ISE, not for actively sharing contextual data with external security platforms.

An Inline Posture Node is a specialized Policy Service Node responsible for enforcing network access and posture policies, particularly for inline traffic redirection, and does not serve as the primary mechanism for sharing contextual information with other security systems.

The Cisco pXGrid (Platform Exchange Grid) Controller within ISE acts as the central point for sharing real-time contextual information, such as user and device identity, group assignments, and security posture, with integrated security products like Cisco Stealthwatch. pXGrid provides a secure, publish-subscribe framework for this bidirectional data exchange.

The Policy Administration Node (PAN) handles the centralized management, configuration, and database for Cisco ISE, but it is not the functional component responsible for real-time contextual information exchange with external systems like Stealthwatch.
