Web Content Filter
The Web Content Filter configuration provides the ability to enable web content filtering on supervised iOS devices. You can specify one or more permitted as well as blocked URLs. Once the web content filter is configured, the web URLs that devices attempt to access would be allowed or denied based on filter.
AutoFilter Mode
Under autoFilter mode, the Safari browser will automatically filter out unsafe URLs and will restrict accessing those URLs.
Whitelist Mode
Under whitelist mode, you can specify permitted URLs for iOS devices. These URLs are saved on devices as bookmarks. You can also specify a bookmark folder location relative to the root folder on the device.
