Completely redesigned Network Monitor
The new map view in Network Monitor shows realtime information about all current and past network connections and their geographic location. It provides powerful filtering and selection options helping to assess particular connections based on the server’s location.
It’s now also possible to create and change rules with a single click right from within the Network Monitor. This is especially useful in conjunction with the new Silent Mode. You may run Silent Mode for a while, then later create rules for connections that occurred during that time (those connections are displayed with a blue Allow/Deny button).
An application’s connections shown in the connection list are now displayed grouped by domain, making it easier to create rules that match an entire domain instead of just a single host. But it’s still possible to drill down to the host-level of each connection.
The connection information is persisted across restarts of the application (i.e. logout/login or restarting the computer).
While the Network Monitor window is open, the app has a Dock icon and it’s shown in the Command-Tab app switcher of macOS.
A new “Since Timestamp” filter allows to temporarily clear the connection list, and to show only connections that occurred after the filter was turned on. The filter can be activated by choosing “Since Timestamp” from the filter menu in the search field, or by pressing Command-K.
You can choose between a light and a dark appearance of the Network Monitor window. The desired appearance can be selected in the View > Appearance menu in the menu bar.
Improved Connection Alert
In Little Snitch Preferences > Connection Alert you can now choose the options that shall be preselected when a new connection alert is shown.
It’s now possible to choose if the created rule shall be effective in the current profile or in all profiles.
The details sections now shows code signature information for the connecting process.
The Connection Alert now offers an “Only local network” option if a connection attempt was made to an address in the local network.
