Security Status

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

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 for Mac runs inconspicuously in the background and it can also detect network related activity of viruses, trojans and other malware.

Features and Highlights

Silent Mode – Decide Later
There are times where you don’t want to get interrupted by any network related notifications. With Silent Mode you can quickly choose to silence all connection warnings for a while. You can then later review the Silent Mode Log to define permanent rules for connection attempts that occurred during that time.

Research Assistant
Have you ever wondered why a process you’ve never heard of before suddenly wants to connect to some server on the Internet? The Research Assistant helps you to find the answer. It only takes one click on the research button to anonymously request additional information for the current connection from the Research Assistant Database.

Automatic Profile Switching
Rules can be arranged in different profiles like “Home”, “Office” or “Mobile Internet”. This allows you to use different sets of filter rules depending on the network you are currently connected to. Profiles can be activated either manually from the status menu, or automatically, whenever you join a network that’s associated with one of your profiles.

Firewall for incoming connections
Little Snitch for macOS not only reveals any outgoing network connection attempt to make sure that sensitive data doesn’t leave your computer without your consent. The inbound firewall in LittleSnitch provides you with the same level of control for incoming connections.

Note: Requires 64-bit processor. The demo runs for three hours, and it can be restarted as often as you like. The Network Monitor expires after 30 days.

What's new in this version:

Network Monitor:
- New option in context menu of Network Monitor to focus on connections of a particular process
- Connections of other users are now hidden by default in Network Monitor to prevent confusion of having e.g. multiple instances of Safari and Mail (owned by different users) shown in the connection list. You can still enable the display of these connections in the view options menu in the toolbar, by choosing “Show Connections of Other Users”.
- Improved display of connections without an existing allow or deny rule in the connection list, showing a completely empty allow/deny button instead of no button at all
- Improved display of connections via iCloud Private Relay on the map. Since the actual IP address of the server is unknown for these connections, it’s not possible to determine their actual location. Little Snitch therefore collects all these connections under a virtual location labeled “Private Relay”.
- Improved keyboard navigation in connection list to expand the “more items” section by pressing the right arrow key twice
- Improved display of process paths in the inspector view
- Clicking a process path in the inspector now opens a menu offering to show the app in Finder or to copy the path

Configuration:
- Added several new filter options in the rule window, accessibly by long-clicking the filter buttons in the search field
- When viewing the contents of a blocklist, there’s now a new “Used Entries” section (which is shown by default), presenting only those blocklist entries that have been used at least once
- Preventing the search string from getting cleared when switching between different blocklists
- Other new features and improvements
- Improved accessibility via VoiceOver
- Improved Wi-Fi name detection using the CoreWLAN API in favor of other methods. Wi-Fi name detection is required for Automatic Profile Switching
- Improved installer to better handle Agent installation issues
- Further improved detection of Homebrew executable paths

Fixed:
- Fixed a rare crash or hang due to a leak of file descriptors when Automatic Profile Switching is enabled
- Fixed a bug in the littlesnitch rulegroup Terminal command where the requested rule group or blocklist was not found
- Fixed a bug where clicking the “Delete All Redundant Rules” button in the Redundant Rules filter section did nothing
- Fixed an issue causing the map to open with a rather small width after launching the Network Monitor
