Introduction to FGT_3400E-v6-build0505-FORTINET.out.zip

This enterprise-grade firmware package delivers FortiOS 6.4.5 build 0505 for FortiGate 3400E hyperscale firewalls, engineered to address critical infrastructure security demands in carrier-grade networks. Designed for environments requiring 99.999% uptime, this Q3 2024 release enhances virtual domain (VDOM) traffic isolation while maintaining 200Gbps threat prevention throughput with full UTM activation.

Exclusively compatible with the 3400E series (FG-3400E), this .out file contains a complete system image for hardware-level disaster recovery. Network architects managing multi-tenant data centers will benefit from improved BGP route reflector scalability and 30% faster SSL inspection throughput compared to previous 6.4.x releases.
