Introduction to FGT_200E-v6-build1319-FORTINET.out Software

This firmware update delivers critical security patches and network optimizations for Fortinet’s 200E series Next-Generation Firewalls, specifically engineered for mid-sized enterprises requiring 10Gbps+ threat inspection capabilities. Released under FortiOS 6.4.15 branch in Q1 2025, build 1319 addresses 14 CVEs while enhancing SD-WAN performance for hybrid network environments.

Designed for FG-200E appliances deployed in distributed office networks, this maintenance release combines hardware-specific optimizations for NP6 network processors with backward compatibility for existing security policies. The update particularly benefits organizations using 200E models with 10GbE interfaces for high-density VPN deployments.
