Little Snitch is a host-based application firewall for macOS. It can be used to monitor applications, preventing or permitting them to connect to attached networks through advanced rules. It is produced and maintained by the Austrian firm Objective Development Software GmbH.
Unlike a stateful firewall, which is designed primarily to protect a system from external attacks by restricting inbound traffic, Little Snitch is designed to protect privacy by limiting outbound traffic.[2] Little Snitch controls network traffic by registering kernel extensions through the standard application programming interface (API) provided by Apple.[3]
Aug 04, 2016 Take control of your Mac! Little Snitch 3 is the best, strongest firewall for macOS that protects your privacy! Little Snitch 3 works on macOS Sierra, OSX El. Mar 02, 2020 Little Snitch License Key is the best-ever opportunity to monitor malevolent activities even if you know or not. You can view your network traffic flow from the MAC network. It tells you about the network rules why it blocks the site and what is the problem. Youill spend some early days training Little Snitch, but the payoff in the long run is that no data will leave your computer without your consent. That provides a lot of peace of mind.
If an application or process attempts to establish a network connection, Little Snitch prevents the connection. A dialog is presented to the user which allows one to deny or permit the connection on a one-time or permanent basis. The dialog allows one to restrict the parameters of the connection, restricting it to a specific port, protocol or domain. Little Snitch's integral network monitor allows one to see ongoing traffic in real time with domain names and traffic direction displayed.
The application (version 4) received a positive 4.5/5 review from Macworld.[4]

Assuming you’ve downloaded the Little Snitch Disk Image (.dmg file) to your Downloads folder, open a new Terminal window and enter the following command to verify the cryptographic signature of the downloaded file:
codesign --verify -R='anchor apple generic and certificate leaf[subject.OU] = MLZF7K7B5R' ~/Downloads/LittleSnitch*.dmg
If the result of this command is empty (no error message is shown), the file is intact and properly signed by Objective Development.

However, if an error message is shown (like “not signed at all” or “failed to satisfy specified code requirement(s)”), this indicates that the file was maliciously modified and is no longer signed by Objective Development. In that case you should NOT open the disk image file.
