VLANs isolate departments (HR, Finance, Guest, IoT) to contain security breaches and optimize broadcast traffic on corporate networks.
Best practices include separate VLANs for servers, workstations, printers, CCTV cameras, and VoIP phones with inter-VLAN routing controlled by firewall policies.
CloudDevNest configures Cisco, Ubiquiti, and MikroTik equipment with documented VLAN schemas and access control lists.
