This is bad architecture. Let me show you why.

 

I have Comcast. Most of my clients do, too -business and executive homes. In 100% of cases when we walk in the door and see this very basic internet architecture, we know that you're already hacked. Why? Comcast, Frontier, Verizon, Spectrum; it doesn't matter who you use, this architecture provides ZERO protection from what's happening on the internet. 

Take six and a half minutes out of your day and watch this short cybersecurity education burst. I think you'll find it useful.
