Knox Guard

Knox Guard is a Samsung Knox cloud service that enables carriers, retailers, and financial partners to protect their devices and enterprise assets from fraud and theft.

With Knox Guard, you can:

• Detect devices that are offline, possibly due to theft, loss, or the user purposely avoiding network connection.
• Display non-dismissible notification messages.
• Lock devices and restrict USB, Bluetooth, NFC, factory resets, and firmware updates.
• Block Android Debug Bridge (adb) communication and access to the Developer Options menu.
• Remove devices from Knox Guard when they no longer need to be secured.

You can use these features through the Knox Guard console or the Knox Guard REST API, which enable you to integrate these capabilities into your organization’s public or private web service.
