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:

  • Allowlisting: Only URLs added in this filter can be viewed on the device browser, while all other URLs are blocklisted (restricted from viewing on the device browser).
  • Blocklisting: URLs added in this filter cannot be viewed on the device browser, while all other URLs are allowlisted (can be viewed on the device browser)

Other than restricting URLs, Web Content Filter also provides the option of restricting content, whereby websites with malicious content are automatically blocked irrespective of whether the website URL has been allowlisted or blocklisted. Web Content Filter is applicable for Non-Samsung devices running 5.0 or later versions, only if provisioned as Profile Owner or Device Owner and Samsung devices running 5.0 or later with Knox version 2.6 or later. To check the Knox version, go to Settings -> About Device -> Knox version.For Samsung devices running on Android 6.0 and above, legacy enrollment is sufficient for web content filter to function.

  • 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.
  • In Non-Samsung devices, Web Content Filter is applied only to Chrome and not to other browsers. In Samsung devices, Web Content Filter is applied to all the browsers on the device.
