What is a major benefit of utilizing Virtual Domains (VDOMs) in a FortiGate firewall?

Utilizing Virtual Domains (VDOMs) in a FortiGate firewall primarily serves the function of separating network and security policies within the same physical device. This separation is crucial in multi-tenant environments where different teams or departments may have distinct security requirements and varying levels of network access needs.

By implementing VDOMs, administrators can create virtual instances of the FortiGate firewall, each with its own set of security policies, configurations, and network segmentations. This allows for tailored policies that fit specific organizational needs, without the need for multiple physical devices. This most notably enhances security management, as all policies can be managed centrally while still ensuring that data and traffic for different virtual domains remain isolated from each other, reducing the risk of cross-contamination or data breaches.

While separation of network and security policies is a clear benefit, other options like increased hardware costs, enhanced user interface options, and reduced complexity in device configuration do not accurately reflect the advantages provided by VDOMs. In fact, deploying VDOMs can lead to cost savings since multiple virtual firewalls can run on a single physical unit rather than investing in additional hardware.
