macOS Defensive Apps


  • ​Little Snitch: It will monitor every connection made by each process. Depending on the mode (silent allow connections, silent deny connection and alert) it will show you an alert every time a new connection is stablished. It also has a very nice GUI to see all this information.
  • ​LuLu: Objective-See firewall. This is a basic firewall that will alert you for suspicious connections (it has a GUI but it isn't as fancy as the one of Little Snitch).
