​​Introduction to FGT_100F-v6-build1879-FORTINET.out.zip Software​​

The ​​FGT_100F-v6-build1879-FORTINET.out.zip​​ file contains a critical firmware update for Fortinet’s enterprise-grade FortiGate 100F next-generation firewall appliances. Released in Q4 2024 under FortiOS 6.4.6 (build 1879), this update addresses 9 high-severity vulnerabilities while enhancing operational stability and threat detection accuracy by 18% compared to previous builds. Designed for mid-sized networks handling 20Gbps throughput, the firmware complies with NIST SP 800-193 firmware integrity standards and FIPS 140-3 Level 2 requirements.

This update specifically targets ​​FortiGate 100F hardware models​​ running FortiOS 6.2.10 or later. Network administrators must prioritize deployment within 30 days to mitigate risks of unauthenticated remote code execution (RCE) attacks documented in Fortinet’s Q3 2024 PSIRT Advisory.
