MDM stands for Mobile Device Management, which is a system that performs compliance checks and remote wiping on mobile devices. MDM allows administrators to enforce security policies, monitor device status, and remotely manage devices in case of loss, theft, or compromise. MDM can also integrate with other Cisco security solutions, such as ISE, AMP, and Umbrella, to provide enhanced protection and visibility for mobile devices. References:
