I dunno - I was at an organization that got booted off of the Internet for various reasons - and while it was a pain for some tasks, it didn't have quite the impact I expected it would have.

So yes, we have WAY too much shit on the Internet that has zero reason to be there - and we have way to many connections and content flowing between orgs without any kind of assessment as to what the content is, it's authenticity, etc.

The vast majority of ransomware incidents happen via spearfishing over email - pretty nuts that literally one erroneous click by a user can take down an entire network.

Think about that. Talk about inherent fragility!

I think this idea has some merit.
