Sophos SafeGuard Disk Encryption for Mac offers full-disk encryption (FDE) for the Mac. FDE scrambles the entire contents of a disk drive, rendering it unrecoverable without access to the encryption key used. Sophos relies on its own user accounts set up as User and Admin categories, which means extra account management instead of using Mac OS X authentication. SafeGuard is a good choice for anyone who prefers not to rely on Apple for their encryption needs for whatever reason.”]
