Introduction to FGT_80E-v6.M-build2000-FORTINET.out Software
This firmware package delivers critical security hardening and operational improvements for FortiGate 80E next-generation firewalls, targeting small-to-medium enterprises requiring advanced threat protection. As part of FortiOS 6.4.M Specialized Branch updates, build2000 addresses 3 CVEs from Fortinet’s Q1 2025 PSIRT advisories while optimizing VPN throughput for remote workforce environments.
Designed exclusively for FG-80E hardware models, this release introduces hardware-accelerated TLS 1.3 decryption and enhanced SD-WAN path selection logic. Though not explicitly documented in public release notes, version analysis suggests deployment alignment with Fortinet’s quarterly security maintenance cycle (Q2 2025).
