Little Snitch 3.0 preview - Alerts you to outgoing networking connections.. (Demo): "

Little Snitch 3.0 is currently in beta. For the latest stable release, see Little Snitch 2.5.3. Little Snitch 3 requires Mac OS X 10.6 or later; 2.5.3 requires 10.4 or later.

Little Snitch alerts you to outgoing network connections.

A firewall protects your computer against unwanted guests from the Internet. But who protects your private data from being sent out? Little Snitch does!

As soon as you're connected to the Internet, applications can potentially send whatever information they want to wherever they want.

Sometimes they do this for good reason, on your explicit request. But often they don't. Little Snitch allows you to intercept these unwanted connection attempts, and lets you decide how to proceed.

Little Snitch informs you whenever a program attempts to establish an outgoing Internet connection. You can then choose to allow or deny this connection, or define a rule how to handle similar, future connection attempts. This reliably prevents private data from being sent out without your knowledge. Little Snitch runs inconspicuously in the background and it can also detect network related activity of viruses, trojans and other malware.

Further Improvements

• In order to support multiple simultaneous logins, processes are distinguished by the user account that started the process. Rules can be created so that they apply to processes running on behalf of the current user, on behalf of a system account such as e.g. root, or on behalf of any account.
• 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.
