1. Introduction to FGT_200E-v6-build0484-FORTINET.out Software

This firmware release (build0484) delivers critical security updates and system optimizations for FortiGate 200E series next-generation firewalls operating on FortiOS 6.4. Validated through Fortinet’s Security Fabric integration program, the update resolves 8 documented vulnerabilities while enhancing threat detection capabilities for enterprise branch office deployments.

Specifically engineered for FG-200E hardware appliances, this firmware revision became generally available on May 10, 2025. It maintains backward compatibility with existing FortiOS 6.4 configurations while requiring 4GB RAM and 128GB SSD storage for optimal performance in medium-traffic network environments.
