What is the primary benefit of using VLANs in FortiGate configurations?

Using VLANs in FortiGate configurations primarily enhances security and management of network segments. VLANs (Virtual Local Area Networks) allow network administrators to segment a physical network into multiple logical networks, enabling better control over traffic flow and security. Each VLAN operates as an independent broadcast domain, which helps to isolate sensitive data and communications from other parts of the network.

By using VLANs, organizations can enforce policies specific to each segment, making it easier to manage security measures, such as access controls and firewall rules. This segmentation is crucial for preventing unauthorized access, containing potential breaches, and simplifying the application of security measures tailored to different departments or user groups within an organization.

While VLANs can indirectly support other aspects like reducing broadcast traffic, simplifying cabling, or adding to available IP address space, their primary role and most significant benefit lie in enhancing security and management capabilities of the network.
