1. Introduction to FGT_2000E-v6-build0163-FORTINET.out.zip Software
This firmware update (build 0163) delivers critical security enhancements and performance optimizations for FortiGate 2000E series next-generation firewalls running FortiOS 6.4. Released in May 2025 under Fortinet’s Extended Security Maintenance (ESM) program, it addresses 19 documented vulnerabilities while improving hardware resource efficiency for large-scale enterprise networks requiring high-throughput threat prevention.
Designed for FortiGate 2020E/2040E/2060E models with dual NP7 network processors, this update targets organizations managing hyperscale traffic environments exceeding 40Gbps throughput. Compatible devices must run FortiOS 6.4.14 or later as a baseline requirement.
