A plea... Deanna and I have been running this site since 2008 and lately we're seeing a big increase in users (and cost) but a decline in percentage of users who donate. Our ad-free and junkware-free download site only works if everyone chips in to offset the revenue that ads on other sites bring in. Please donate at the bottom of the page. Every little bit helps. Thank you so much. Sincerely, your Older Geeks: Randy and Deanna Always scroll to the bottom of the page for the main download link. We don't believe in fake/misleading download buttons and tricks. The link is always in the same place. Portmaster Free v2.2.1 👉 Take complete control of your computer's network traffic and protect your privacy. Portmaster Free is a powerful open-source application firewall and privacy manager that lets you see, understand, and control every network connection made by your computer. Instead of simply allowing or blocking Internet access, Portmaster provides detailed visibility into which applications are communicating, where they are connecting, and what protocols they are using. Designed with privacy in mind, Portmaster automatically blocks many trackers, advertisements, malware hosts, and unwanted telemetry across your entire system rather than just within your web browser. It also secures DNS requests, provides extensive per-application and global network controls, and gives advanced users the flexibility to create highly customized filtering rules. Unlike traditional firewalls that focus mainly on inbound threats, Portmaster concentrates on outbound traffic, helping you identify applications that quietly phone home, collect telemetry, or communicate with unexpected servers. Whether you're a privacy enthusiast, security researcher, or simply want more insight into your computer's network activity, Portmaster offers one of the most comprehensive free solutions available. The free edition includes all core privacy and firewall functionality. Premium Safing features such as SPN (Safing Privacy Network), investigative tools, and priority support are optional and not required to use Portmaster's primary firewall and privacy capabilities. Features: Monitor every incoming and outgoing network connection Interactive application firewall with per-app network permissions System-wide blocking of ads, trackers, and malware domains Secure DNS requests using encrypted DNS-over-TLS Create global and application-specific firewall rules Block individual domains, IP addresses, countries, or connection types Restrict peer-to-peer traffic to selected applications View detailed connection history and network statistics Control Internet access with simple allow and block rules Automatic filter list updates for improved protection Open-source software with publicly available source code Automatic background updates for intelligence data and components Supported operating systems: Windows 10 (64-bit), Windows 11 (64-bit) Ubuntu (64-bit), Debian (64-bit), Fedora (64-bit), Arch Linux (64-bit), Linux Mint (64-bit), other modern 64-bit Linux distributions Supported languages: English Changes: v2.2.1 06-11-26 New: Initial support for Apple Silicon (macOS ARM64) Apple notarization support Support for additional Linux distributions Improved Linux installer and packaging Improved Windows installation and service handling Better update handling and reliability Improvements: Improved DNS monitoring Improved application detection Better network compatibility Improved stability and performance Numerous user interface refinements Fixes: Multiple Windows, Linux, and macOS bug fixes Numerous firewall, networking, DNS, and UI fixes Various stability and reliability improvements throughout the application  This download is for the Windows 64bit version (very bottom of page).
