if you allowed that to happen you either did not set firewall rules strict enough
The argument was that the vlans force a device through the firewall so that the firewall can protect it. But for that to happen, like you said the firewall wasn’t strick enough or didn’t have a defense against a 0 day.
So the vlan doesn’t do anything either way. Either the firewall works in which case you don’t need vlans to force local traffic through them a second time or they don’t work in which case again the vlan did nothing.
