  If you set it up incorrectly you can perform an attack called vlan hoping.

  You also need to setup Firewall rules to properly isolate zones

  VLANs are for organizing traffic, not authorization of traffic.

    Only if you don’t set it up correctly. You should set which devices are allowed to set which vlans and then make sure client devices aren’t authorized to send or receive tagged packets.

    You then combine that with a firewall only needed traffic allowed.
