 - Web Content Filtering is restricted to specific browsers via process name. This means that web content filtering doesn't work when there is a local proxy application in place (such as Fiddler), due to the originating process name being masked. Web content filtering does not function in isolated browser sessions (i.e. Microsoft Defender Application Guard). 
 
-- Web Content Filtering is based on Network Protection. Blocking in third-party browsers requires that the browser be configured [properly to enable content inspection](network-protection#required-browser-configuration). Because full URLs are not available in third-party browsers, blocking access to certain web applications may require creating a custom block indicator for the application's login page. Keep in mind, such a block might block users from accessing other services associated with the same website.

 - Web Content Filtering classifies billions of URLs, but new sites are added every day, and new sites may not be immediately detected. Even after a site is categorized, the content on any site may change at any time. Classifying a site's content is inherently a subjective process. Given these constraints, you should expect that new sites may not be immediately categorized, and a site's category may be changed at any time. For full control over your users' access to sites, create a Custom Indicator to allow or block the site.
