IGEL OS 11.06 or higher offers strong device encryption that is derived from a user password. The encryption is applied to all partitions that can contain user data, e.g. browser history or Custom Partitions.
Important Notes on Downgrading
If you have encrypted your IGEL OS 11.06 device, downgrading to IGEL OS 11.05 or lower will imply data loss on the following partitions, due to different partition schemes:
Browsing history of the browsers Firefox and Chromium
Custom Partitions
The device settings and the UMS connection are preserved.
The device encryption password must be entered by the user.
Instructions
In the UMS configuration dialog or the local Setup, go to Security > Device Encryption.
