WatchDox is an enterprise-focused solution to the growing need for secure document sharing and mobile collaboration.

You can browse through workspace folders, see all documents in your WatchDox Exchange inbox, designate documents or folders for automatic sync, annotate documents, and render documents in any format. WatchDox protection allows the document owner or enterprise admin to wipe out or restrict access to documents at any time – even ones that have been forwarded or downloaded previously.
