Windows11firewallcontrolplus

is a third-party security utility developed by Sphinx Software designed to extend and enhance the native Windows Defender Firewall. Unlike the basic on/off toggle of the default Windows firewall, this tool provides outbound notification-based filtering , per-application rule management, and granular control over network traffic. It serves as a middle ground between the simplistic Windows firewall interface and complex enterprise-level solutions like hardware firewalls or advanced endpoint protection.
