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:
- Connections from helper processes that are contained within an app bundle are now attributed to their parent app in the connection list of Network Monitor, so they no longer show up as separate, nested connections
- The connection list now shows more useful names for XPC helper processes running from a temporary, random path which may no longer exist
- Improved information shown in the inspector’s header section when an app group or app extension is selected

Configuration:
- The rule list now shows an info text overlay for empty search and filter results (explaining why the list is empty)

Connection Alert:
- If the Network Extension frameworks provides the URL leading to a connection, this information is now shown in the details section of the connection alert

Bug Fixes and Improvements:
- Improved the installation process to initiate a retry sequence if the Agent process did not start after installation
- Fixed a missing localization in the Endpoint Security installation dialog on macOS Sonoma. This bug prevented the installation of the Endpoint Security system extension on Sonoma.
- The “Select All” and “Deselect All” commands no longer worked in Network Monitor
- The Command-Delete keyboard shortcut for removing connections from the connection list no longer worked in Network Monitor
- Fixed the incorrect appearance of another “Private Relay” label, shown in the map
- Fixed an issue causing updates of the geolocation database to happen too often or not at all
- Fixed a display issue in Network Monitor when hovering certain elements in the inspector with the mouse, causing the displayed icon to overlap with the underlying text
