Introduction to FGT_4401F-v7.0.9.M-build0444-FORTINET.out
This firmware package delivers FortiOS 7.0.9M for FortiGate 4401F series next-generation firewalls, addressing critical security vulnerabilities while enhancing enterprise network protection capabilities. Released under Fortinet’s quarterly security advisory cycle, this build specifically resolves 12 CVEs identified in SSL-VPN, IPSec, and web filtering subsystems since January 2025.
Designed for high-performance security operations centers, the 4401F chassis platform benefits from improved threat detection latency (measured at 3.2μs throughput improvement) and extended compatibility with SD-WAN Orchestrator v5.3+ configurations. The “M” designation indicates this maintenance release contains security patches without major feature changes, making it ideal for organizations requiring stable operations continuity.
