When administrators search for the "latest FortiGate firmware," their primary driver is usually a specific CVE. The last 12 months have seen high-profile vulnerabilities that make upgrades mandatory.

The most frequent mistake organizations make is assuming they can upgrade from FortiOS 6.4 to 7.4 directly.
