DEKSI USB Security is a security software for blocking all USB devices that are connected to your computer or to a computer connected to a network. This kind of tool is very useful in order to prevent data theft in a firm. It can detect all types of removable storage devices connected to a PC such as USB drives, memory cards, flash disk, portable hard disk, etc, and prevent them from being connected to your computer.
