This policy setting controls whether users see a security warning when they open custom Document Information Panels that contain a Web beaconing threat. InfoPath can be used to create custom Document Information Panels that can be attached to Excel workbooks, PowerPoint presentations, and Word documents. 

If you enable this policy setting, you can choose from three options for controlling when users are prompted about Web beaconing threats: 

- Never show UI 

- Always show UI 

- Show UI if XSN is in Internet Zone 

If you disable or do not configure this policy setting, the behavior is the equivalent of setting the policy to Enabled -- Never show UI.
