Which antivirus and attack definition update options are supported by FortiGate units?

The option indicating that updates can be manually downloaded from the support site is supported by FortiGate units. This method allows administrators to directly source antivirus and attack definition updates when needed, providing greater control over the update process. It is especially useful in environments where internet access may be limited or where a more curated update approach is preferred.

Updating manually can help ensure that the specific versions of the definitions are applied, and allows organizations to maintain consistency across multiple devices by applying the same updates at scheduled intervals. This approach also facilitates cybersecurity auditing processes, as all updates can be tracked and managed more systematically.

Other options do exist for updating antivirus and attack definitions, but they rely on different mechanisms. For example, pulling updates from FortiGate or pushing them from FortiAnalyzer represents automated processes that may not provide the same level of control as a manual download. Using the CLI command to execute updates is more technical and might not be the preferred approach for all users, making manual downloads a more accessible and manageable option overall.
