Symantec this week announced two new data encryption options. One is file-based encryption for use with Dropbox, and the second is an extension to the Apple iOS mail client to encrypt and decrypt documents. The new products will be available in January. The encryption for Dropbox files can also be used without setting a group policy as well as the company setting its own policy on the service. The second product to be out is expected to cost $225 per user, but the popularity of Dropbox prompted work on file encryption.”]
