privacy firewall

The privacy firewall tag on WindowsForum.com covers discussions about software that monitors and controls network traffic on Windows PCs to enhance privacy. A recent thread examines Portmaster, a free open-source privacy firewall from Safing that visualizes per-app connections, enforces custom rules, encrypts DNS by default, and applies system-wide tracker and malware blocklists. The thread highlights the need for careful configuration and notes known quirks with DNS and VPN compatibility before relying on such a tool for a production workstation. This tag is relevant for users interested in Windows network security, per-application firewall rules, and privacy-focused traffic filtering.
