Configuring Data Leakage Prevention

Note Data Leakage Prevention is not supported for Endpoint Web Control.

The Configuration > Global Policy > Data Leakage Prevention page allows appliance administrators to enable or disable posting capabilities for their users on select webmail sites, and on sites categorized as Blogs & Forums.

When your users attempt to send a webmail message or post a message to a blog, and you have data leakage prevention enabled, they could very likely see an error message generated by the webmail or blogging site rather than a notification page from the Web Appliance itself.

To manage Webmail control:
1. Click On to the right of Webmail control to prevent your users from sending webmail on the listed sites.
  
  This feature applies to the following webmail sites: Google Mail (Gmail), Yahoo! Mail, Windows Live Hotmail, and AOL Mail.
