Introduction to FGT_100EF-v6-build1066-FORTINET.out Software
This firmware release (build 1066) delivers critical security and performance updates for FortiGate 100EF series appliances operating under FortiOS v6 architecture. Designed for mid-sized enterprises requiring multi-gigabit threat protection with 10GbE connectivity, this version addresses 9 CVEs identified in previous FortiOS 6.4.x deployments while introducing hardware-accelerated security processing optimizations.
Compatible exclusively with FG-100EF hardware platforms, the update enhances SSL inspection capabilities and improves SD-WAN orchestration efficiency. Network administrators managing distributed office networks or healthcare systems will benefit from its enhanced threat prevention accuracy (up to 5 Gbps) and reduced administrative overhead through automated policy management features.
