The Intel ISST Extension (by Everest) is a driver related to (ISST), which is part of Intel's advanced management and monitoring system for enterprise environments. This technology is designed to provide insights into system health, performance, and power usage for Intel-based systems. "Everest" refers to a system monitoring software used in conjunction with Intel ISST to gather and display data on various system parameters, particularly for servers and workstations.

Intel ISST can be used in enterprise and data center environments to monitor the overall health of the system, including CPU utilization, thermal status, power management, and other metrics, while "Everest" (a software by Lavalys) provides the tools to interface with and visualize this data.
