The reason we were talking about on-prem is because we're talking about the effort of doing these things yourself vs farming it out to a third party.
If you're a security engineer responsible for securing only:
1. a public website
2. stuff that can be ip whitelisted and/or use mTLS
Consider yourself very lucky. Most orgs need to expose a lot more than that.
Almost no companies farm their security out to third parties. The era of MSSPs is long dead, except for small non-IT businesses like mom-and-pop law firms.

No, in fact there are only 2 kinds of connections:
1) public, necessarily allows anonymous/unauthenticated connections
2) non-public, doesn't need to allow unauthenticated connections
Name a service, and I can tell you which one it is.
Or put another way, there are authenticated and unauthenticated services. If you can authenticate someone at the application level, you could do it at the network level.
Most places have combined them at some boundary, for ease of access, but there is no case in which an authenticated application endpoint (even /login) has to allow unauthenticated network access to it.
And in all seriousness, name a service that is not a public website, but cannot use mTLS or IP allowlisting.
SFDC? mTLS. Customer webhooks? IP whitelisting. Data warehouse? PtP VPN.
