Special Technical Support firmware

Special Technical Support firmware was formerly known as Top3 builds. When Special Technical Support (STS) firmware is running on FortiGate instead of General Availability (GA) firmware, it is labeled as STS in the FortiOS GUI and CLI, and warning messages about the risks are displayed. STS builds are signed by Fortinet.

This example shows how to use the FortiOS GUI and CLI to identify when FortiGate is running an STS build of firmware.

See also BIOS-level signature and file integrity checking.

To view an STS build in the GUI:

1. Log in to FortiOS. A warning message is displayed.

   

2. Click I Understand The Risk to acknowledge the warning and complete the login process.

3. View the STS build label and warnings:

   • Go to Dashboard > Status > System Information widget to view the red (STS) label in the Firmware field, for example, 7.4.1 build4291 (STS).

     

   • Hover over the FortiGate name on the left corner of the banner to display a tooltip. The Version fields displays (STS), for example, 7.4.1 build4295 (STS).

     

   • Click admin on the top-right of the banner to display a menu. The (STS) label appears at the end of the version, for example, 7.4.1 build4295 (STS).

     

   • Hover over the exclamation mark beside STS on the top-right of the banner. A Special Technical Support (STS) firmware installed warning is displayed.

     

To view an STS build in the CLI:

1. Log in to the CLI. The console prints the following warning message:

   Login: admin
   Password
   ******WARNING: This is a Special Technical Support (STS) firmware.******
   STS firmware is issued by Fortinet to select customers in order to provide features and fixes that are not yet generally available. Plesae use caution when running STS firmware in production and consult with authorized Fortinet support personnel regarding configuration changes, fabric integration, and firmware upgrades.

2. Get the system status.

   In this example, the STS build is identified by (STS) and a certified firmware signature.

   # get system status
   Version: FortiGate-201F v7.4.1,build4295,230817 (STS)
