​​Introduction to FGT_90E-v6-build1175-FORTINET.out Software​​

This firmware update (build 1175) delivers critical security enhancements and operational optimizations for FortiGate 90E series firewalls running FortiOS 6.x. Released in Q4 2024, it addresses multiple high-severity vulnerabilities while improving network performance for small-to-medium enterprises.

Compatible exclusively with FortiGate 90E hardware models (FG-90E, FG-91E), this update aligns with Fortinet’s December 2024 security advisories. System administrators managing distributed networks should prioritize installation to mitigate risks associated with unpatched SSL-VPN services and memory allocation flaws.
