Introduction to FGT_90E-v6.M-build2000-FORTINET.out Software
The FGT_90E-v6.M-build2000-FORTINET.out firmware represents Fortinet’s latest security-hardened release for its FortiGate 90E Next-Generation Firewall, designed for branch offices and small enterprises requiring enterprise-grade threat protection in a compact form factor. As part of FortiOS v6.4’s Maintenance Release (v6.M) branch, this build delivers 15 Gbps firewall throughput with enhanced SSL inspection capabilities – a 20% performance improvement over previous builds.
Officially released on February 28, 2025, this firmware specifically targets the 90E hardware platform, addressing 4 critical CVEs identified in Fortinet’s Q4 2024 security audit cycle. It maintains backward compatibility with Security Fabric integrations while introducing new IoT device profiling capabilities for operational technology (OT) networks.
