Did you know that many applications on your Mac secretly send data to the internet – often without you noticing? This is exactly where Little Snitch comes in: a powerful network monitoring software that gives you full control over your Mac's network traffic.
What is Little Snitch?
Little Snitch is a firewall software for macOS that monitors every single network connection. As soon as an application tries to establish a connection to the internet, Little Snitch shows you a notification – and you decide whether the connection is allowed or blocked.
Key Features at a Glance
1. Real-Time Monitoring
Little Snitch shows you in real-time which applications are trying to access the internet. You can see exactly:
- Which app wants to establish a connection
- To which server the connection is going
- What data is to be transmitted
2. Allow or Block Connections
For each new connection request, you can decide whether to allow or block it. You have the choice between:
- Allow/block once
- Allow/block permanently
- Allow for a specific time
3. Create Custom Rules
Little Snitch allows you to create detailed rules for individual applications. You can, for example, specify:
- Allow only specific domains
- Allow connections only in a specific network (e.g., home network)
- Block certain ports
4. Silent Mode
When you're working with focus and don't want to be disturbed by notifications, activate Silent Mode. Little Snitch then automatically applies your predefined rules without interrupting you.
5. Integrated Network Monitor
The Network Monitor gives you a detailed overview of all active connections. You can:
- See which applications are currently transmitting data
- View the amount of data transferred
- Analyze connections in real-time
Why is Little Snitch Important for Your Privacy?

With Little Snitch, you stay in control and decide for yourself which data may leave your Mac. This not only protects your privacy, but also helps block unwanted advertising trackers.
