Open The Secure Browser
Open Enigm Link from the official USB. The desktop app prepares the protected environment and presents two primary modes:- Secure browser: opens Enigm Command in an isolated temporary browser window.
- Secure boot: guides compatible computers into the Enigm Link Boot OS environment.

Confirm Protected State
The secure browser flow should show that the temporary session is prepared and that the environment is protected. The protected state indicates that Enigm Link has prepared the controlled environment and validated the required product state. A normal network connection alone is not enough; protected state depends on Enigm Link environment preparation and product validation. The lower-left status pill indicates the current environment state:Environment protected
The protected environment is ready and the secure browser can be opened.
Protecting environment
Enigm Link is still preparing the environment. Wait until protection completes.
Environment not protected
The environment is not protected. The secure browser remains unavailable until protection is restored.

Secure Boot Flow

Shut down completely

Connect the USB

Power on the computer and open the boot menu immediately. Common keys include 
F12, F11, F10, Esc, or Option on Mac.
4
Choose the Enigm USB
Select the Enigm Link USB entry. If the same USB appears twice, select the 
UEFI option.
5
Wait for the protected environment
Let the USB load until the protected browser opens. Enigm Link runs isolated from the installed computer session.

6
Finish safely
Sign out of Enigm, shut down from the protected environment, and remove the USB only after the machine is completely powered off.

Troubleshooting
Common user-facing cases:- The environment is not protected: wait for Enigm Link to finish preparing the environment, then retry from the official USB.
- The update button appears: run the update from inside Enigm Link and keep the USB connected until completion.
- The USB appears twice in the boot menu: select the
UEFIentry. - The boot menu does not appear: restart and try the boot-menu keys shown by the product flow.

- Enigm Command account controls.
- User verification decisions.
- Host-device security awareness.
- Safe handling of downloaded files or credentials.
