The Windows Firewall API is used by over a billion Windows users world-wide including information security professionals, and IT pros. Would you trust someone to disable that firewall and replace it with unknown and untested technology?
We would not, and that’s why we chose to use the Windows Firewall API for GlassWire.
The blocking part of GlassWire is a tiny part of the application. Most people are excited about GlassWire because is visualizes their network activity and reveals suspicious app activity. One of the first people to download our software found malware their antivirus had completely missed, and this was completely unrelated to the Windows Firewall API.
I see no email from you? You can contact us privately here https://www.glasswire.com/contact/ with your order information. Please don’t post your private order info to the forum, thanks.
Also you said the Windows Firewall crashed and is unusable. This is easy to fix. Go to the Windows Firewall control panel and choose “restore defaults” then reboot your PC.
Another nice thing about the Windows Firewall API is that even if the third party app using it is killed, the firewall can still block. Third party firewall applications can’t usually claim that ability. Also our firewall continues to work on startup before GlassWire even starts. Most other firewalls can’t do that either.
