You should already know that an effective firewall is essential, protecting your computer while it’s connected to the internet. But did you know that Windows Firewall is a viable solution built into the Windows operating system?
Windows Firewall offers all the functionality you’d expect from a firewall, including application filtering, packet filtering, and circuit-level filtering. While this filtering is mainly designed to deal with incoming connections as opposed to outbound traffic, it’s an effective way to secure your desktop.
In addition, Windows Firewall is an excellent choice for enterprise. You can deploy configurations through your AD Group Policy, login scripts, and unattended setup scripts, enforcing your firewall policies across every Windows PC.
