Discussion

Continuous scanning capabilities on the Cisco ISE provide visibility of devices that are connected to the switch ports. The Cisco ISE continuously scans networks and monitors the activity of managed and unmanaged devices, which can be personally owned or rogue endpoints. Because many of today's small devices do not include agents, an agentless discovery is often combined to cover more types of equipment.
