Customizing the Block and Notification Pages

Steps

  1. To begin, go to Email and Block & Notification Pages:

  2. Expand the URL Sandboxing section, browser isolation is best used with the Prompt for Analysis and Uncategorized URL notification pages.
  3. Click HTML Editing.

  4. Edit the code to add the ability to send the URL environment variable to Forcepoint RBI. Here is a sample reference code. Replace <yourrbiaddress> with your Forcepoint RBI URL.

  6. Click Save.

  7. Click Preview to verify that the HTML code is valid.

    The link will not work in Preview mode as it requires an actual website URL to be sent from Forcepoint. Send an email through Forcepoint Email Security with a URL that will be detected as suspicious to trigger the response page. Clicking the link on the actual response page will launch the rewritten URL and send the original URL to browser isolation for safe viewing.
  8. To restore the block page back to the original, click on Revert to Default and then click Save.
