FGT_80F-v6-build1378-FORTINET.out.zip: FortiOS 6.4.12 Security Update for FortiGate 80F Series

​​Introduction to FGT_80F-v6-build1378-FORTINET.out.zip Software​​

This firmware package delivers critical security enhancements and system optimizations for FortiGate 80F series next-generation firewalls under FortiOS 6.4.12. Designed for small-to-medium business networks, build 1378 addresses 12 documented vulnerabilities while introducing hardware-accelerated threat detection capabilities validated by FortiGuard Labs.

Exclusively compatible with FortiGate 80F hardware variants (80F/80F-3G4G/80F-POE), this release maintains backward compatibility with configurations created in FortiOS 6.2.x. Deployment records indicate phased distribution began in Q3 2025 through Fortinet’s authorized partner network.

​​Key Features and Improvements​​
