What is the main benefit of using VLAN tagging with access points?

Using VLAN tagging with access points primarily allows for the creation of separate firewall policies for different SSIDs. This means that each SSID can be associated with a unique VLAN, enabling more granular control over network traffic and security settings. By isolating different types of traffic—such as guest access, employee access, and IoT devices—network administrators can apply specific security measures and policies tailored to each user group.

This capability enhances security and operational efficiency since it allows for the segmentation of users and devices on the network. Each VLAN can enforce rules such as bandwidth limitations, access controls, and even different types of threat detection, reducing the attack surface and allowing for a more secure environment.

While signal strength, management simplicity, and overall speed may be influenced by network design and equipment choices, they are not the primary advantages provided by VLAN tagging. The real value lies in the enhanced flexibility in managing traffic and ensuring appropriate security measures through tailored firewall policies for each VLAN tagged SSID.
