Manage Block Pages

  • Click 'Configure' > 'Policy Settings' > 'Block Pages'

Block pages are shown to end-users when they attempt to visit a site that is banned by one of your policies. This includes users of endpoints in your protected networks, and all roaming endpoints.

  • You can create any number of block pages and apply them to different policies.
  • You can customize the content and behavior of block pages. The available options are:
  • Show the same block page for all types of of rule violation
  • Show different block pages for category, security and blacklist rule violations
  • Display custom block message(s) with your custom banners
  • Redirect users to a specific webpage
  • You need to install the Secure Internet Gateway SSL certificate on all protected endpoints. This so the block page displays correctly over HTTPS connections.

    Step 1 - Configure Block Page Content


    First, choose whether to show a single block page or different block pages:

    • Show a single page for all blocked domains - A same block page is shown regardless of the type of rule is violated.
    • Show different pages for blocked domains - Show specific block pages when a certain type of rule is violated. You can show different pages for category rule breaches, security rule breaches and blacklist rule breaches:




    • You can type a custom message for each page if required.
    • Alternatively, you can use the default message of 'Please contact your system administrator for your access policy'
    • You also have the option to redirect to a different URL instead. Please specify the full URL if you use this option. For example, https://www.example.com/security-redirect-page.php

    Step 2 - Upload Your Logo

    • The interface shows the Secure Internet Gateway logo on the block page by default.
    • You can change this to your own company logo by uploading a suitable .png or .svg file
    • Click 'Upload Image' under 'Choose Logo'. Browse to the location of your image and click 'Open'




    Note: Max. file size = 50 kb. Images must be in.png or .svg format
