1. Introduction to FGT_4401F-v6.M-build2095-FORTINET.out

This firmware package delivers FortiOS 6.4.17 for FortiGate 4401F series appliances, specifically engineered for hyperscale data center deployments requiring 200Gbps threat inspection throughput. The build 2095 update focuses on operational continuity in multi-tenant environments, featuring non-disruptive security service upgrades and extended hardware lifecycle support until Q3 2032.

Designed for carrier-grade networks, this release enhances VXLAN routing performance while maintaining backward compatibility with FortiManager 7.4+ centralized management systems. The firmware exclusively supports FortiGate 4401F hardware appliances with dual NP7 network processors, providing deterministic latency below 5μs for financial trading networks.
