    I may not be exactly, or as good as GlassWire, but as a lightweight, free and open-source alternative it definitely provides a very decent and totally unbiased firewall, giving maximum protection to the end-user over which apps and services have access to the open internet.

    It's Open Source and the internals are much better documented, no security tool is perfect but at least here if you're a professional you can see how to works to know what it is and is not capable of. However with GlassWire they just give generic help desk responses whenever you ask questions, either because they don't know or are just trying to cover it up for marketing.

    It's just like glasswire except for the fact that portmaster has more features than glasswire, and it is also for more advanced users.
