You might be surprised, but Windows Firewall is a powerful firewall. Personally I use BitDefender Internet Security or Commodo Firewall, but if I had a client that wasn’t wanting to use a firewall I would definitely would use Windows Firewall. Unfortunately, Windows Firewall doesn’t offer a user-friendly interface and there some features are missing from the firewall that most firewall software has.
This is where Windows Firewall Notifer comes in. Windows Firewall Notifier adds features to the Default Windows firewall by adding a way to handle outgoing connections and displaying (almost) real-time information about the current connections.
How Windows Firewall Notifier Make Windows Firewall Better
Windows Firewall just doesn’t run along side the default firewall or even run in the background all the time. It somehow adds itself into actual Windows Firewall.
When you install Windows Firewall Notifier, it will activate Windows Firewall if its deactivated and by default its set to block all outgoing traffic. The software then creates a log of all outgoing connections then triggers a notification popup asking what you want to do with each out going connection. Image Source: How-To Geeks
