Issue: Some Web sites might allow PDF files that contain data which violates a policy to be printed from within the browser. The user will not receive notification of a policy violation and no incident will be logged in the Symantec Data Loss Prevention reports. This issue can occur when viewing a PDF through an internet browser such as Microsoft Internet Explorer or Mozilla Firefox.
This is a problem related to viewing a remote PDF in a Web browser. Depending on the Web browser and how the PDF is hosted on the Web site, the remote PDF cannot be scanned for a policy violation.
