I`m a long time user of this software on Windows XP OS and very contend with it. Since March 2007 I upgraded to version 3.9 which is the latest version compatible with Vista 32bit and the software has been optimized in its routines so that the on-the-fly encryption/decryption process is now faster. I find that the features of this software like: the possibility of hiding of an entire operating system inside the free space of another operating system, pre-Boot authentication, multiple OS boot support (Microsoft), no size limitation for encrypted disks, steganography in order to hide data into picture, Trojan and keyboard sniffer protection preventing passwords from being sniffed / captured (red screen modus), anti dictionary and brute-force attack mechanisms, USB-Token authentication at pre-boot level, recovery disk for "disaster recovery" and the fact that it is easy to install, deploy and use makes this product a valuable one to use.
