Why you don't need a VPN or not?
-
@Obsolesce - Right, I have an edge firewall for the WAN to the LAN where all endpoints on the wired network (servers and clients) reside, but I am wondering how to move to a tighter circle to get the servers segregated from the clients.

Segregated how or in what sense? So they cannot communicate to each other?

That involves making network services available with a different method.
IE: Files served from NextCloud instead of a file server.

@Obsolesce - So they are not wide open (with the exception of the Windows firewall).

OK, so if I am not doing that, there is no point to make a change?

The second diagram shows the red security perimeter, housing "Servers, SANs, etc. All applications, files, and every other resource needed". What is securing the perimeter?

Generally VPN in the form of HTTPS connections.

@wrx7m said in Why you don't need a VPN or not?:
@scottalanmiller So in a transitional phase of moving away from LAN-centric practices, I have Windows firewall enabled on all Windows clients and Windows servers. Is that it, or would I have servers behind a hardware firewall with an ACL?
Firewalls are nearly always a good thing. Not always necessary, but rarely "bad". Certainly you want the OS firewalls on servers and desktops, always. LANless won't mean necessarily dumping your hardware firewalls, they are necessary as the routing layer, anyway. So using ACLs and NATing are going to continue to be useful.
The key difference is ensuring that they are a "secondary defense layer" and not a primary one. Make sure you'd feel safe putting your server on the Internet... then add that hardware firewall as icing, not as your security cake.
-
@travisdh1 said in Why you don't need a VPN or not?:
LANless is about making everything accessible through web services.
And securing them as if they will be accessed over the Internet.
But not web services, necessarily, although commonly. Accessed as if they are remote is a better way to phrase it.

Do you really want "servers versus clients?" Making servers secure individually is great, but generally servers need to talk to clients more than to other servers. Keeping servers away from each other is often more important than keeping servers away from clients. Same deal with clients, they almost never should talk to each other, but constantly must talk to servers.

LANless requires removing LAN-based approaches. I understand you are talking about a transition period.
But some things, like SMB shares and Active Directory are LAN-based at their cores and really have to effective way to be made LANless, even transitionally.
I mean you can do something like taking ZeroTier and encapsulating SMB and creating a poorly performing LANless file sharing service in that way. But it is hokey and won't behave all that well. SMB is just not suited to that, it was designed with the thought that LAN containment would always define it.

No. Web isn't more secure. Web might be easier to secure and to make LANless, but only because people are used to thinking of web as LANless and SMB as LAN-based. So assumptions go a long way.
NextCloud is not LANless only when used via web, but when used other ways, too.

I think that this diagram can be misleading. It's showing a single service. But in a normal LANless infrastructure, you'd have a "red zone" for every workload, rather than just one, it might be dozens.

So, would you say more like the previous comment where it would be services/servers with their own, respective perimeters? If so, what is the perimeter built from?

Clients can't talk to other clients per the Windows firewall rules I've configured. I will have to audit the servers to identify and prevent unnecessary communication between them.

Generally just firewall and service rules. The service should be secure itself without relying on access to the LAN on which it sits to protect it.
