Introduction to FGT_240D-v6-build0484-FORTINET.out.zip Software
This firmware package delivers critical security updates and performance enhancements for FortiGate 240D next-generation firewalls under FortiOS v6.0.15, specifically designed for medium-sized enterprises requiring robust network protection. Released as part of Fortinet’s extended support cycle, this build addresses 9 CVEs while optimizing hardware resource utilization for environments with up to 1.4 million concurrent sessions.
Compatible exclusively with FortiGate 240D (FG-240D) appliances manufactured after 2019, the firmware supports FortiOS v6.0.x Long-Term Support (LTS) branch until December 2026. System administrators managing distributed retail networks or healthcare infrastructure will benefit from its backward-compatible security policy framework and improved threat intelligence integration.
