Introduction to FGT_200E-v6-build0419-FORTINET.out Software

This firmware update delivers enterprise-grade security enhancements for FortiGate 200E Next-Generation Firewalls, designed for mid-sized networks requiring multi-gigabit threat protection. As part of FortiOS 6.4.19 released in Q2 2025, the build addresses 18 documented CVEs including vulnerabilities in SSL-VPN authentication protocols and IPv6 packet fragmentation handling.

Specifically optimized for the FG-200E hardware platform, this version introduces hardware-accelerated deep packet inspection while maintaining FIPS 140-3 Level 2 compliance. Network administrators managing distributed workforces will benefit from improved SD-WAN path selection algorithms and automated threat intelligence synchronization with FortiManager 7.6+ ecosystems.
