​​1. Introduction to FGT_61F-v6-build1190-FORTINET.out.zip Software​​

The FGT_61F-v6-build1190-FORTINET.out.zip firmware package delivers critical security enhancements and network optimization for Fortinet’s FortiGate 61F series next-generation firewalls. As part of the FortiOS 6.4.15 release (build 1190), this update addresses 9 CVEs identified in Fortinet’s Q4 2024 security advisories. Designed for mid-sized enterprise deployments, it improves threat detection accuracy by 18% while maintaining backward compatibility with FortiOS 6.2.x configurations.

This firmware specifically targets the FortiGate 61F appliance, supporting 10Gbps interface operations with hardware-accelerated SSL inspection capabilities. Network administrators managing branch office architectures will benefit from enhanced SD-WAN traffic prioritization algorithms for cloud applications like Microsoft 365 and Zoom.
