Which feature allows administrators to monitor and control devices connected to the network in real-time?

Context Visibility is a critical feature within Cisco Identity Services Engine (ISE) that enables administrators to gain comprehensive insights into the devices connected to their network. This capability allows for real-time monitoring of devices, providing visibility into the device type, operating system, and user identity, among other attributes. By leveraging this feature, administrators can establish a clearer understanding of who is accessing the network and what devices are connecting, which is essential for security monitoring and resource management.

This real-time insight into device connections enables administrators to make informed decisions about network policies, compliance, and security measures. With Context Visibility, ISE can visualize the network environment, empowering administrators to quickly identify anomalies or unauthorized devices, thus enhancing the overall security posture of the organization. This level of monitoring goes beyond simple access control; it provides a holistic view that is crucial for proactive network management.

In contrast to other features mentioned, such as Policy Sets, which define access conditions based on attributes but do not directly monitor devices, or Network Access Devices, which are limited to the hardware utilized for access control, Context Visibility specifically focuses on the monitoring and tracking of devices. Guest Access Management primarily addresses the needs of temporary users, without providing the same breadth of visibility into the entire network environment.
