You can customize the appearance of Umbrella block pages, or redirect to your own custom page altogether. If you do not wish to change anything, you can keep the default appearance.

Once you have created a custom block page appearance setting, you can apply it to your policies as you see fit.

1. Navigate to Policies > Policy Components > Block Page Appearance and click Add.

2. Give your new setting a meaningful and easy to remember name. For example, Corporate Appearance.

3. Select The Same or Differently.
   Different block pages can be presented depending on the type of block, such as whether the reason for the block was due to a content setting, or a destination list entry. Alternatively, you can treat every block type the same and present a generic block page.

3. Click Save.
