Disk Defensor is a transparent(on-the-fly) disk/cd encryption system,which combines with AES 256-bit encryption.It can make a disk partition encrypted on the windows system or create some new virtual disks and cds.Using this encryption software does not require any particular actions or change in your routine activities.After encrypted, all the operation for this encrypted disk is as the same as a normal disk, when read and write, the decryption and encryption engine is running at background and transparently. Disk Defensor doesn't allow you to read and write the right data on the disk partition until the disk is unlocked with the correct password. The contents of the encrypted disk are well protected by Disk Defensor, a unique data protection mechanism that guards your data from Trojans, viruses or other types of malware.It is really a time-proven solution for encrypted data storage and backup.
