Whenever a user attempts to navigate to a blocked site, they will be presented with a page notifying them that they are attempting to access a blocked site and that they should get in touch with an administrator if they believe this has happened in error.
If desired, there are various components of the block page that can be customized.
Creating a new block page appearance setting

Creating a new block page appearance

Umbrella offers to display the same block page for all pages, in addition to displaying a different page for sites that were blocked by a category, destination list, phishing, or security setting.
After choosing whether or not to show a different block page depending on what type of request was being blocked, select what will display when a block page is encountered. If desired, enter a custom message to display, or redirect users to a different page.
