Web Content Filter


MDM lets you control the contents that can be viewed on the browsers of managed devices using Web Content Filter. Web Content Filter lets you Blocklist or Allowlist URLs as explained below:

Other than restricting URLs, Web Content Filter also provides the option of restricting content, whereby websites with adult content are automatically blocked irrespective of whether the website URL has been allowlisted or blocklisted. Web Content Filter is applicable for Supervised devices running iOS 7.0 or later versions. Enabling Automatic restriction of inappropriate content ensures that inappropriate content is restricted on the devices. Apple restricts inappropriate content based on blocklisted keywords such as adult content, and content to be restrained from children below 18.

  • Blocklisted URLs can be still be accessed if the corresponding app is present on the device. For example, even if all Facebook URLs have been restricted, users can still access Facebook, if the app is installed on the device. To prevent this, the apps must be blocklisted as explained here.
  • Blocklisting/allowlisting HTTP version of the URL automatically Blocklists/Allowlists the HTTPS version of the URL and vice-versa.
  • If a blocklisted URL is redirected, then the restriction will not be applied on the redirected URL, unless it is also blocklisted
  • Wild card-based URLs such as *.example.com, https://*.com etc., are not supported.
  • Mobile version of the URL and country based domain extensions should be considered as separate URLs. Example : facebook.com, facebook.co.uk, m.facebook.com, etc
