Introduction

When Forcepoint web protection policies are used to block a user from accessing a website or cloud application, a block page is displayed in the user’s browser. This block page is constructed from a series of HTML, CSS, and JavaScript files. You can customize the block page to adapt it to the needs of your organization and your end users.

It is helpful to have HTML, CSS, and JavaScript knowledge before attempting to create custom block pages. Excellent HTML and CSS reference information is available from w3schools.com.

The articles in this collection describe how to use the default block pages supplied with your on-premises web protection software as a template for creating your own customized block pages. It is also possible to:

• Create your own HTML files from scratch, then configure Filtering Service to pull in content from those files when it generates a block page.

  See Using an alternate block page on another machine in the Administrator Help.

• Display custom content in the top frame of a block page only, without customizing the entire block page.

  See Creating alternate block messages in the Administrator Help.

• Customize the block pages used by the hybrid service.

  See Customizing hybrid block pages in the Administrator Help.
