But if you look at that above link that you posted
http://www.symantec.com/business/whole-disk-encryption
This excerpt from the top states:
PGP® Whole Disk Encryption from Symantec provides organizations with comprehensive, high performance full disk encryption for all data (user files, swap files, system files, hidden files, etc.) on desktops, laptops, and removable media. The encrypted data is protected from unauthorized access, providing strong security for intellectual property, customer and partner data. Protected systems can be centrally managed by PGP Universal Server simplifying deployment, policy creation and distribution and reporting.
Notice the bottom part that I put in bold. Talking about purchasing a PGP Universal Server to centally mange and deploy Whole Disk Encryption.
I'm sorry for the confusion, but I would probably direct your question at our Sales team. Since they are the ones who would have sold you the product.
