DNS to Nowhere
If you have gone through the process of setting up DNS-based security for your home (Pi-Hole) or enterprise (Cisco Umbrella) network that’s awesome, you have greating increased the security of that network.
If done right this will give you the ability and visibility to see what is happening and control what’s going on with your network with clients that use internal DNS. If you have not take the time to identify, update, and block clients from using external DNS servers, you have a gap in your DNS security.
