Glossary: What is a Virtual LAN (VLAN)?

VLANs group devices logically, enabling efficient communication and improving security by isolating traffic in large networks.

A Virtual LAN (VLAN) is a way to logically segment a network, allowing devices to communicate as if they were on the same physical network, even when located in different areas. VLANs reduce congestion, isolate traffic, and improve security - especially in large enterprise environments.
