Little Snitch by Objective Development is a powerful macOS firewall and network monitoring tool that gives you full control over your Mac’s internet connections. It monitors all incoming and outgoing traffic in real time and alerts you whenever an application attempts to connect to the internet, allowing you to allow or block connections instantly.

Designed for privacy-conscious users, developers, and security professionals, Little Snitch acts as an application-level firewall for Mac. It reveals hidden network activity, prevents unauthorized data transmission, and helps you stop trackers, ads, and suspicious connections before any data leaves your system.

With advanced rule management, DNS encryption, and detailed network insights, Little Snitch is widely recognized as one of the best firewall apps for macOS for monitoring and controlling outbound connections.
