For organizations relying on Fortinet’s FortiGate next-generation firewalls (NGFWs), the phrase "latest FortiGate firmware" represents more than a simple software update. It is the frontline defense against emerging zero-day exploits, a gateway to cutting-edge SD-WAN and SASE features, and a compliance requirement for many regulated industries.
