In my opinion, ISE/NAC technology plays a key role in Zero Trust. With a dissolving network perimeter due to cloud services and IoT, the importance of security visibility and controls for endpoints and users becomes even more critical. With ISE you can identify and profile the devices on your network, assess their posture or in zero trust terms – their trust levels, and ensure corporate resources are accessed securely. Segmentation is important in Zero Trust – ISE allows you to deploy software based segmentation controls in your network, and provide a richer level of context through user identity to influence firewall policies that take into account more than a device IP address.
