Checking the current FortiOS firmware

1. To check which firmware version you’re using, go to the Dashboard and view the System Information widget, which shows the current Firmware.

   

2. To find out if a new FortiOS version is available, go to System > Firmware. If new firmware is available, a notice appears under Current version.

   When a new FortiOS version is released, it may not be listed on your FortiGate right away. If this occurs, download the firmware from Fortinet Support, then use Upload Firmware to upgrade your FortiGate.
