Introduction to FGT_90E-v6-build1803-FORTINET.out Software
This firmware package delivers critical security enhancements and operational optimizations for Fortinet’s FortiGate 90E Next-Generation Firewall. As part of FortiOS v6.4.15, build 1803 addresses 11 CVEs rated 8.0+ on the CVSS scale while improving interoperability with hybrid cloud infrastructures. Designed for mid-sized enterprises, the FortiGate 90E appliance supports 5 Gbps threat protection throughput and 10,000 concurrent VPN tunnels.
The update aligns with Fortinet’s Q4 2024 Security Advisory (FSA-2024-35) and resolves vulnerabilities disclosed in recent threat intelligence reports. It maintains backward compatibility with FortiManager v6.4.x centralized management systems and FortiAnalyzer v7.2.x log analytics platforms.
