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.

Nobody will be touching your files.

Sentry can activate if your computer has been idle for a specified period of time, if you click it's icon in the system tray, or if you type a set hotkey. Sentry can also automatically be loaded on startup.

This small, 46 KB trigger program can instantly start Sentry by global hotkey, single click, double-click, popup menu, or after an idle period -- just like a Windows screensaver.  Be confident leaving your workstation knowing that Sentry will be protecting it!

If you want, Sentry can tell people why you are gone or where you went.  With this feature turned on, Sentry will prompt you for an away message each time the computer is locked down.  You can enter up to 10 pre-defined away messages to use.

When Sentry starts because your computer has been idle, Sentry will recognize this and not prompt you for a message (because you're probably already gone!)

If someone walks by your workstation while Sentry is running, they can leave a private message for you to read when you return. The message will show up in Sentry's message panel, and after Sentry ends you can browse any messages left for you. Again, Sentry lets you customize the message behavior with colors, fonts, styles, and more.

Have complete control over the colors and fonts within Sentry. Give it your own look!

Graphic customization

You can brand your Sentry Screen with graphics like a company logo, a comic strip, or anything you want.

Sentry lets you run your existing screensavers within Sentry.

This still gives you the robust security features of Sentry, but adds another layer of beauty to it. You can tell Sentry to load a certain ScreenSaver within a specified time after loading Sentry, and also change ScreenSavers afterwards with the ScreenSaver button.

Upon the first run, Sentry will detect all installed ScreenSavers on your computer and load them into an internal list, where you can configure them from within Sentry (ScreenSavers tab)

Bring Sentry with you to your local computer lab, or wherever!  The program easily copies to a portable device such as a floppy, USB Flash Drive, or CD-ROM  for use elsewhere.   
 

After putting Sentry2Go on a USB drive or a CD, Sentry can automatically lock down the hosting computer upon insertion.
