private disk multifactor is a disk encryption program that secures confidential data on laptops, usb disks and other endpoint devices. it combines the industry standard nist-certified aes 256-bit encryption, an innovative disk firewall mechanism, 64-bit platform compatibility, usb disk portability and smart card authentication into a low-cost and easy-to-deploy solution. it provides proactive protection against viruses, trojans, adware, spyware and unauthorized network access. sensitive data are not only encrypted, but are protected with dekart's innovative disk firewall mechanism: a unique technology that creates a white-list of 'trusted' applications allowed to access the encrypted disk. if a specific application is not found in the white-list of programs, it will be unable to read or alter the confidential information stored on the virtual encrypted disk. support for smart card and biometric devices provides an added layer of data protection by storing the user's private decryption key or strong password on a smart card or usb stick. so if, for example, a laptop is lost or stolen, there will not be any risk of data being compromised. this encryption software is compatible with virtually any version of windows, including the latest 64-bit releases of windows xp and windows 2003. the encryption program's mobility allows it to be used in conjunction with a broad range of portable media, for instance: usb flash drives,external hard disks, flash memory cards, dvds, or digital mp3 players, such as the ipod. private disk multifactor becomes a true usb disk encryption program, as it can be launched directly from the removable media, without having to be installed on the computer, meaning that you can work safely with your data, no matter where you are.
