​​Introduction to FGT_1800F-v7.0.9.M-build0444-FORTINET.out Software​​

The ​​FGT_1800F-v7.0.9.M-build0444-FORTINET.out​​ firmware is a mission-critical update for FortiGate 1800F series next-generation firewalls, engineered to address 21 documented vulnerabilities while enhancing hyperscale data center performance. Released under FortiOS 7.0.9 in May 2025, this build specifically targets organizations requiring 100 Gbps+ threat inspection throughput with zero-trust network access (ZTNA) compliance.

Optimized for the FortiGate 1800F hardware (480 Gbps firewall throughput), this firmware integrates NP7 network processor optimizations and AI-driven threat intelligence from FortiGuard Labs. It resolves critical vulnerabilities in SSL-VPN services while introducing hardware-accelerated TLS 1.3 decryption capabilities.
