Windows Firewall
PC network guardian
Windows Firewall is a security feature built into Microsoft Windows that monitors and filters network traffic, blocking unauthorized connections while allowing legitimate ones.
It acts as a barrier between a computer and potential threats from the internet or local networks: Windows Firewall blocked an incoming connection.
Most users leave it enabled by default.
