Yeah that's also what I would recommend, PVLAN if you have Cisco
switches or others that support the same.
Alternatively, you could create a unique VLAN for every single port,
but that'd be a real pain to setup.
"The PVLAN edge (protected port) is a feature that has only local
significance to the switch, and there is no isolation provided between
two protected ports located on different switches. A protected port
does not forward any traffic (unicast, multicast, or broadcast) to any
other port that is also a protected port in the same switch.
Therefore, it provides isolation. Traffic cannot be forwarded between
protected ports at Layer 2. All traffic passing between protected
ports must be forwarded through a Layer 3 device."
