Introduction to FGT_200E-v6-build0528-FORTINET.out.zip
This critical firmware update delivers essential security hardening and operational improvements for Fortinet’s FortiGate 200E next-generation firewall platform. Designed for small-to-medium enterprise networks, build 0528 resolves 7 documented vulnerabilities while maintaining backward compatibility with FortiOS 6.2.x architectures. The update targets organizations requiring robust threat prevention in 5Gbps network environments with advanced SD-WAN capabilities.
Released under Fortinet’s Q4 2024 security maintenance cycle, this build extends hardware lifecycle support through 2027. The firmware utilizes Fortinet’s fourth-generation Security Processing Unit (SPU4) architecture, maintaining 4.8 Gbps firewall throughput with full deep packet inspection enabled.
