Manage Internet uploads with Portmaster

Rapid Access

For quick access even when the app is closed, Portmaster gives you an icon in the desktop environment's system tray area. Left-clicking on the icon lets you quickly switch between the individual operating modes using the radio button. In addition, you can open the application window or disable Portmaster in the icon's context menu.

Conclusions and Outlook

Portmaster helps you put an end to dubious data transfers from your home computer to software vendors or advertising networks. The sophisticated blocking features not only use filter systems to prevent unwanted data uploads, but also prevent transfers to third parties at the application level if required. This helps you keep track of data traffic and makes it more difficult for trackers and advertising networks to spy on your surfing habits.

The Portmaster/SPN project, which is still at an early stage for such a technically demanding application, has by no means implemented all the planned features. If you're interested in trying Portmaster, you'll find Linux installation instructions at the project website [5]. The developers have also published a detailed roadmap on their website; you can check out the roadmap to find out when a function that you need, such as anonymization on the Internet using the SPN, will be integrated [6]. Portmaster is an effective tool for anyone wanting to keep their private affairs genuinely private.
