1. Introduction to FGT_3401E-v6-build1723-FORTINET.out

This firmware package delivers FortiOS 6.4.7 for FortiGate 3401E series appliances, engineered for hyperscale enterprise networks requiring 160Gbps threat inspection throughput. Released in Q4 2024, build 1723 introduces hardware-accelerated SSL/TLS 1.3 decryption optimized for financial and healthcare sectors with <1ms latency for real-time transaction security.

Designed for multi-tenant data center deployments, this release enhances VXLAN routing performance by 55% compared to FortiOS 6.4.5. It maintains backward compatibility with FortiManager 7.4+ centralized management systems while introducing enhanced telemetry integration for SD-WAN health monitoring.
