PRODUCT DESCRIPTION VPDisk   
 

VPDisk Pro
VPDisk Pro, made as an add-on to your system, instantly adds encryption capability to your existing file-systems. It requires no re-installation of system software, no re-setup of application software, and no migration of existing files and folders
VPDisk Pro makes encryption a natural storage format for files. File-by-file encryption with flexible key management and file sharing is allowed. Its transparent on-the-fly encryption lets owners access encrypted files as if these files were in the clear. All others, including administrative users and hackers, see strongly encrypted data. This transparent separation of data access from information access makes it possible for system administrators to do file backup without being able to see the file content. Since file contents are always encrypted in hard disks and backup tapes, the information is protected even when the hard disks and tapes are stolen.
