DiamondCS Process Guard is an advanced security system that protects both system and security processes (as well as user-defined processes) from attacks by other processes, services, drivers, and other forms of executing code on your system. The first program of its kind, it is made possible by a kernel-mode driver that securely controls process-to-process access in a relatively simple but technically efficient, safe, and secure manner. Although it is a very powerful program due to its low-level nature, its intuitive graphical interface actually makes it very easy to use for both novice and advanced users alike.
