1. Introduction to FGT_2000E-v6-build1778-FORTINET.out
The FGT_2000E-v6-build1778-FORTINET.out firmware package delivers critical security enhancements for Fortinet’s FortiGate 2000E series next-generation firewalls, designed for large enterprises requiring high-density threat prevention and multi-gigabit throughput. This release addresses 14 CVEs identified in Fortinet’s Q2 2025 Global Threat Report while optimizing hyperscale network performance.
Exclusively compatible with FortiGate 2000E chassis systems, this build (v6-build1778) operates under FortiOS 6.4 architecture. The release date of March 25, 2025 marks it as the third maintenance update (6.4.3) for the 6.4 firmware branch, succeeding build 1732 which suffered from memory allocation vulnerabilities.
