Little Snitch for Mac

Overview

Little Snitch is a compact utility for macOS that watches your system and network traffic, identifying applications that might be sending sensitive data off your machine. Unlike standard security tools, it specializes in monitoring outbound connections so you can see which processes are communicating over the internet.

How it differs from traditional protection

A conventional firewall primarily blocks incoming threats such as viruses and malware. It generally does not give you visibility into which programs on your computer are transmitting data out to external servers. Little Snitch fills that gap by focusing on outgoing connections and giving you control over them.

Core features

• Customizable rules that let you allow or block specific connections
• Real-time alerts when an application attempts to reach the internet
• Visual connection history and charts showing network activity over time

Keep your confidential information secure

By combining alerts, configurable policies and visual activity summaries, Little Snitch helps you detect and stop programs that might be leaking personal or sensitive information. Use it to gain transparency and control over your system’s outbound network behavior.
