Hello Everyone,

write to ask if is possible to implement a GPO, which allow us to prevent the user to browsing on any website, except a 'Trusted Site Zone' list.

We have a domain-based environment - Client: Win10 1809 Kiosk Mode - IE 11.

Thanks in advance,
Kind Regards
Giovanni

    Open up Group Policy Management Console (GPMC).
    Create a New Group Policy Object and name it Restrict Internet Access.
    Edit and navigate to: User Configuration -> Preferences -> Windows Settings -> Registry and create a New Registry Item.
    There are 4 registry items we need to create/update: ProxyEnable, ProxyServer, ProxyOverride, AutoDetect

    Hi,
    Thank you for posting in our forum
    Internet Explorer has simple but serviceable cookie controls. There are two main areas we’re interested in: managing site status and toggling the cookie acceptance. First let’s look at how to whitelist a site. Click on Tools [the gear icon in the corner on newer versions] > Internet Options > Privacy > Sites. Here you’ll find the Per Site Privacy Actions menu, which allows you to white or black list web sites.
    Manually entering every site you’d like to whitelist is a bit on the kludgy side, so we’re going to semi-automate the process by toggling the cookie settings. Visit Tools [gear icon] > Internet Options > Privacy, and under Settings, click Advanced.

    Hi,
    Thank you for the update.
    According to my knowledge, with proxy settings is a safer way.
    Recommend you to use this method
