Introduction to FGT_4401F-v7.2.3.F-build1262-FORTINET.out
This firmware release (build 1262) for FortiGate 4401F appliances delivers critical security hardening and network optimization under FortiOS 7.2.3. Designed for enterprise data center deployments requiring hyperscale threat protection, it combines hardware-accelerated security processing with 400Gbps firewall throughput capabilities. The “F” designation confirms feature stability, with build 1262 resolving 11 CVEs disclosed in previous versions.
Exclusively compatible with FortiGate 4401F hardware (FG-4401F), this update enhances hybrid mesh firewall performance and introduces SASE architecture optimizations. Fortinet’s release documentation indicates validation through 1,500+ hours of regression testing, with official distribution commencing in Q1 2025.
