Developed by Fresh Software and designed to support Windows systems, Sentry is an application that helps users to protect their digital data by locking their systems, while they are away. This tool prevents snooping and unauthorized access to a user’s system. This tool also allows users to leave a message at your workstation in your absence. You can customize the program using HTML and use it in combination with your favorite screen saver. You can launch this utility either from the system tray, using hot-keys, or automatically when your system has been idle for a specified time. You can also use this utility on a LAN to lock multiple computers.
