About Knox Guard

Knox Guard is a cloud-based solution that protects you against theft, loss, or financial default on your mobile devices. Using Knox Guard, you can set granular restrictions on the devices such as enable/disable certain SIMs, lock a device when it hasn’t been online for a defined period of time, send payment overdue reminders and much more.

Knox Guard supports Samsung mobile devices running Knox version 3.2.1 or higher.

Key Knox Guard features include:

  • Notifications — To remind users about missing or overdue payments, you can send notifications to Knox Guard enrolled devices.
  • Blink reminders — You can remotely send blinking, non-dismissible, payment reminder messages to delinquent devices until their payment status is restored to good standing.
  • Lock and unlock devices — Knox Guard can lock down a device as a last resort payment recovery option. Once locked, the device’s USB, Bluetooth, NFC, FOTA, factory reset, and binary flashing capabilities are restricted. Once the user’s payment subscription is restored to good standing, you can unlock the device and restore all functionality.
  • Send firmware update reminders — To encourage users to update their device’s firmware to the latest version, you can send update reminders.
  • Block or unblock Android Enterprise provisioning — You can block device provisioning on Knox Guard activated devices, preventing them from enrolling into Android Enterprise.

To review a device’s status flow once it’s added to the Knox Guard console, see the Knox Guard status flow.
