We want to use Cisco NAC and need to check if client Desktop has a firewall installed. This may be not the default Windows Firewall.
Is there some Windows registry key that can be checked?

For non-Windows firewalls, you can use WMI API to detect the presence of a firewall if it’s registered with Windows.
And you can use this little gem to detect if it’s actually on or off.
For Windows Firewall detection, it’s INetFwMgr and friends.
