How many Virtual Domains (VDOMs) are supported on a default FortiGate configuration?

In a default FortiGate configuration, the system supports up to 10 Virtual Domains (VDOMs). VDOMs allow you to partition a single FortiGate device into multiple virtual units, each functioning as an independent firewall with its own policies, configurations, and administration.

This capability is particularly useful for organizations that require separation of environments, such as separating different departments, customers, or even different network segments, while still utilizing the same hardware. By assigning a unique set of policies and resources to each VDOM, users can enhance security and performance tailored to specific needs.

It's essential to keep in mind that the maximum number of VDOMs supported can vary based on the specific FortiGate model and licensing, but the default setting for many common models is indeed 10. This makes it an attractive feature for many users looking to leverage multi-tenancy without needing additional hardware resources.
