What Network Monitor does

Network Monitor is a personal firewall for the Mac you SSH from, deploy from, and leave running. It shows which process connects to which server, where that server is, and lets you allow or deny it.

• A live list groups connections by app, with host, address, port, and protocol.
• A map draws arcs from your Mac to each server. Cities come from an offline database.
• Rules match an app, a host, a domain, an IP, a network, a port, and a protocol.
• The menu bar shows open connections and switches the mode.

Tagline: A personal firewall for developers.

Requirements

• macOS 15 (Sequoia) or later
• The app in /Applications before the system extension can activate
• One approval under System Settings → General → Login Items & Extensions

Turn the filter on

The list and the map show traffic on their own. Blocking starts after the filter is approved.

1. Move Network Monitor to /Applications.
2. Open the app and choose Settings → Filter → Install & Enable Filter.
3. Approve it in System Settings → General → Login Items & Extensions.
4. Pick a mode from the menu bar.

Modes

An alert can allow or deny once, for 15 minutes, until quit, or forever. A tighter rule wins. If two rules tie, deny wins.

Map and geolocation

Server cities come from a database stored on the Mac. No IP address is sent out to look up a location. Your Mac's location is only the origin of the arcs.

Privacy

There is no account and no analytics in the app. Rules and connection history stay on the Mac. Details: Network Monitor privacy policy.
