Name: Little Snitch
Mac Platform: Intel
OS version: 10.8 or higher
Greatly improved support for iOS Simulator apps in Connection Alerts, Network Monitor and Configuration. Read our blog post for details on how iOS Simulator apps are now handled in Little Snitch.
Added support for showing iOS App Extension icons.
Improved handling of via connections:
Connection alerts now show a cancel button if either the parent or the via process is terminated.
Until Quit rules are now valid until both the parent process and via process have terminated.
OS X Yosemite changed how incoming ssh connections are handled. Incoming connections are no longer handled by sshd directly but instead by launchd. On OS X Yosemite, this version of Little Snitch automatically converts existing rules to ensure incoming SSH connections work as expected.
Little Snitch menubar item no longer occupies space when disabled.
Fixed: The process owner in Network Monitor Snapshots was “root” instead of the actual user in many cases. Snapshots now store the user’s names and show them correctly.
Software update checks are now using HTTPS. We will gradually enable HTTPS for all other connections to our servers in the near future.
Little Snitch... 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.
