Introduction to FGT_200E-v6-build1778-FORTINET.out Software

This firmware package (FGT_200E-v6-build1778-FORTINET.out) delivers FortiOS 6.4.3 for FortiGate 200E series appliances, targeting branch office networks requiring 50-80 Gbps threat-protected throughput. Released under Fortinet’s Sustained Engineering Program in Q3 2024, this maintenance build addresses critical vulnerabilities while enhancing interoperability with SD-WAN ecosystems.

Exclusively compatible with FortiGate 200E hardware, the update supports deployments where hybrid WAN optimization and zero-trust access converge. The firmware aligns with NIST SP 800-193 resilience standards and Fortinet’s quarterly security hardening cycle, making it ideal for enterprises balancing security and operational continuity.
