  • When no user is logged in, all connections which are not covered by an existing rule are automatically denied. Rule suggestions are created for these connections and can be reviewed in Little Snitch Configuration.
  • If you can't login without network access (e.g. network accounts), the system can be restarted in Permissive Mode where all connections are allowed before the first user logs in. Allow-rules are automatically created so that future logins succeed. Permissive mode is also used during the first restart after installation, but not after upgrades.
  • All components are code-signed.

  • Changes since Release Candidate (3871)

  • Help is now available for Little Snitch.
  • Fixed an issue where Ask-Rules could cause a Connection Alert to be shown even in Silent Mode.
  • Fixed a bug where the Connection Alert wrongly indicated that the process terminated.
  • Fixed an issue where rules created from the Connection Alert were for process owner "System" instead of the current user.
  • Connection Alert now honors modifier keys that were held before the alert was shown.
  • Fixed unexpected change of filter scope when creating rules from rule suggestions.
  • Fixed potential crash of Little Snitch Network Monitor when deleting connections from the list.
  • Little Snitch Network Monitor can now be activated with LaunchBar. Simply add /Library/Little Snitch/Little Snitch Network Monitor.app to LaunchBar's index.

Little Snitch tells you when a program tries to send info to the internet so you can see whats going on in the background! You start an application that tells you that a new version is available. You suddenly realize that with every start this application connects to the developer's server. Even statistics information about your computer may be sent this way. Little Snitch helps you avoid this situation. Trojan horses - i.e. programs transmitting unconsciously data stored on your computer - can be detected by Little Snitch and prevented on the transmission of data.

Features:

  • Prevents applications from "phoning home"
  • Protects you from trojans, worms, and other network parasites
  • Shows which applications send information over the internet
  • Provides a higher level of security for the paranoid

"Reply to David Barnhouse:"

I think all you need to do is go to System Preferences (click the Apple in upper-left of screen, click "System Preferences").

2. Then click Accounts.

3. Next click your account (your username).

4. Click the "Login Items" tab near the top-middle of the window.

5. Finally, click on "Little Snitch . . " (if it's there) and click the - (minus) that is close to the bottom of the window.

That should keep Little Snitch from running when you start your machine or log in.

Pros
  • Great for intermediate and expert users who want to know what's going on with their machines.
Cons
  • Frequent pop-ups can be baffling for novice users.
