What is Portmaster?
Portmaster is a free and open-source application firewall that puts you back in charge over all your computer's network connections.
Features:
Monitor All Network Activity Discover everything that is happening on your computer. Expose every connection your applications make and detect evil ones. Finally get the power to act accordingly.
Block Unwanted Connections Many programs connect to the Internet without your knowledge. When you find unwanted connections, you can now simply block them.
Auto-Block via Selected Filter Lists Automatically block ads, trackers and malware hosts via trusted domain-lists, which are also used by Ad-Blockers, etc. Easily change the defaults to fit your needs.
Enforce DNS-over-TLS Even with invasive connections gone, you might not want to share your dns requests out in the open. With the Portmaster, you can easily re-route all your dns queries to a DNS-over-TLS provider of your choice.
Set Global & per-App Settings Make your own rules. Completely cut off applications from the Internet. Or block all p2p connections except for certain apps. Or never connect to specific countries. The Portmaster has you covered.

Blogpost Portmaster VS Simplewall https://safing.io/blog/2022/04/11/portmaster-vs-simplewall/
Interesting program.. shows you connections, the countries they are in, etc. User interface could be a smidge friendlier.. such as when approaching/leaving SPN. I wanted to see if I could use the program as a sort of task killer,, but it isn't meant for that.
This company is the biggest scam. While the Portmaster application is decent, the SPN dos not work properly. I fell for their smooth show and kind and fast customer service. But when i found out the service was not working properly and they wanted to start charging for it, i requested a refund.
Hell started with these guys. All kind of excuses came up why they could not refund and now they even stopped replying all together while still having my money...
Sdly I was forced to contact a company to take legal actions again this scam company.
Be warned! Do NOT give them any cent what so ever. They simply steal your money.
I simply do not beleive you. Probably it was user error, and top of that we are discussing the firewall here, not other services.

Portmaster - a wonderful program that works exactly as promised. Simple and clear graphical interface, display of all currently running processes, detailed information about each connection to a process and clear display of allowed and blocked connections.
It detects application's internet access before other firewalls like simple wall.
