See every connection your Mac apps make and block the ones you did not allow
PacketWarden is a Mac firewall and network monitor for you if you want to see where apps connect, limit their network access, and investigate background data use.

What you get
You decide which app connections get through and see what happens in the background.
You get a view of where your Mac apps send data, so you can investigate background activity instead of guessing. PacketWarden shows outgoing connections as they happen, including destinations and data transferred. You can also receive an alert when an app contacts a server it hasn’t used before.
You can cut off an app’s network access, block a domain across all apps, or require approval before any connection gets through. Curated blocking lists help you reduce ad, tracker, and telemetry traffic. When you need unrestricted access temporarily, you can pause protection without deleting your rules.
You can look back through connection history and bandwidth charts to find apps transferring data quietly. Search by app or host, separate blocked traffic from allowed connections, and export records to CSV for review. Your connection history stays on your Mac, with no account or traffic-data upload required.
