Sentry locks down your computer on demand so it stays secure when you aren't using it. No other programs can be opened, no browser history can be snooped at, and nobody will be touching your files while you're gone. Sentry can even take messages from people who dropped by your workstation while you were away. You can customize the appearance of your screen while Sentry is running, and have your favorite Ecrans de veille run within the program. Sentry can launch from a Système tray icon, a global hotkey, or after your computer has been idle (no keyboard/mouse input) for a certain amount of time. The Sentry2Go feature lets you copy the program to removable media such as a floppy disk, USB flash drive, or CD-rom, allowing you to quickly lock any public workstation you may be using. Sentry is ideal for people in workplaces who may have to leave their Système unexpectedly and don't want co-workers to snoop around in their files. It's also useful for teachers, parents, etc, who don't want the kids messing with their computer if it's left on.
