Credant Mobile Guardian 5.1 Enterprise Edition

Originally published online in another form

Microsoft's Encrypting File System has its limits--it doesn't support detailed data management and cannot keep information secure when it's legitimately (or not) copied to PDAs and removable storage media. Other encryption tools aim to do better, with most taking the full-disk encryption approach. The Credant Mobile Guardian (CMG) takes a different route. It lets administrators define policies that list which file types and directories should be encrypted, which encryption standard should be used, whether to encrypt data copied to removable storage media and much more.

The data-encryption process is completely transparent to end users, and concerns over data loss from lost or corrupted encryption keys is addressed through automatic key escrow on the enterprise server when the keys are first created.




CMG Web Interface allows for easy management of enterprise policies for all desktops, laptops, and PDAs.

There are trade-offs in choosing Credant's approach over the full-disk approach, though. File directory information on desktops, laptops, PDAs and removable storage media is accessible. On the other hand, with a full-disk-encryption product, booting the OS decrypts the hard drives. Credant avoids that by not encrypting the Windows and Program Files folders, so rebooting is possible. The files and folders you do encrypt are decrypted only as needed.
