Portmaster is a free and open-source application firewall and privacy suite for Windows and Linux desktops. It intercepts all network traffic at the packet level to monitor connections, block trackers and malware, enforce secure DNS, and apply per-app rules, with an optional paid onion-routing network (SPN).
Use cases
- block apps from phoning home
- block ads and trackers system-wide
- encrypt all DNS queries with DNS-over-TLS
- monitor which applications make network connections
- set per-application firewall rules
- restrict app connections to certain countries
- replace my VPN with per-connection privacy routing
When to choose
- you want automatic, default-on privacy protection on a Windows or Linux desktop
- you need visibility and control over every application's network activity
- you want system-wide tracker and malware blocking beyond the browser
- you prefer fully local, auditable open-source privacy tooling
When to avoid
- you need a firewall for servers or headless environments
- you require macOS or mobile support
- you need only a simple VPN without per-app control
- you cannot run kernel-level packet interception on your machine
