1. Introduction to FGT_800D-v6-build0365-FORTINET.out Software
This firmware release delivers mission-critical security updates and infrastructure hardening for FortiGate 800D enterprise firewalls operating in high-traffic environments. As part of FortiOS v6.0’s extended support branch, build 0365 resolves 18 documented vulnerabilities while introducing hardware-specific optimizations for the 800D’s NP6XLite network processors.
Specifically engineered for the 800D hardware platform, this version enhances threat protection capabilities with 40 Gbps SSL inspection throughput and 25% faster IPS signature matching compared to previous v6.0 builds. Network administrators managing financial institutions or healthcare data centers should prioritize deployment to address critical risks in SSL-VPN and IPv6 routing subsystems.
