Knox Guard 22.03 release notes

Last updated July 26th, 2023

Improvements to device lock based on IMSI change

A new IMSI Lock menu is available under the SIM control page. This feature allows customers to enable or disable IMSI policies regardless of whether MCC/MNC information is provided. This feature is implemented in the case where the IMSI is changed after a different SIM card is inserted into the device.

Updates to Knox Guard menu labels

To support more use cases, the menu labels on the Knox Guard portal now use more general terms. For example, Default lock screen now displays as Lock screen.

Device lock and wipe

For missing or stolen devices, IT admins can lock and wipe the contents of the device through Actions > Wipe out. The device wipes as soon as it connects to a server. This action is irreversible.
