Apple’s macOS Firewall is a handy tool for users who need a high level of security, as it blocks unauthorized Internet connections from reaching your Mac.

Lulu is a free macOS application designed to complement macOS’ firewall by adding automatic blocking for all outgoing Internet connections.

Additionally, when the VirusTotal icon in the alert window is clicked, LuLu will query VirusTotal’s servers using the process’s hash and display the detection rate for that process.

You can also click the Process Hierarchy icon to quickly view the parent name and PID of the process if you need more information about the process you want to create the remote connection to.

After completing the process analysis, you can click the Block or Allow button to create a new firewall that LuLu can use in the future to allow or prevent applications from creating network connections in the future.

The list of rules can be accessed by launching the application or by clicking on the rules entry in the LuLu status bar item. In the Rules window, you can add new firewall rules using the Add Rule button, or delete any of them by clicking the X icon next to the entry.
