Your network settings stay as they are.

How GuardianBlock works

In your browsers

  • Browser policies

    Browsers show “Managed by your organization”. That organization is GuardianBlock.

  • The GuardianBlock extension

    In Chrome, Edge, and Firefox, kept on.

  • Guest mode, Incognito, InPrivate

    Chrome Guest mode is off. Incognito and InPrivate are off on a standard Windows account.

  • A native messaging host

    Connects the extension to the service.

On Windows

  • Two Windows services

    GuardianBlock Service and GuardianBlock Recovery Monitor, each of which restarts the other after an unexpected stop.

  • A tray app

    Starts when you sign in and shows protection status.

  • An App Control policy

    On the protected Windows account, blocks known alternative browsers from running.

  • One entry in Installed apps

A laptop you also use for work.

A personally owned PC qualifies when setup finds no device management or policy conflicts.
