Introduction to FGT_240D_POE-v6-build0457-FORTINET.out

This firmware package (FGT_240D_POE-v6-build0457-FORTINET.out) delivers critical security updates and hardware optimizations for Fortinet’s mid-range FortiGate 240D Power over Ethernet (PoE) series appliances. Designed for enterprise branch offices requiring advanced threat protection, this Q1 2025 release addresses 12 CVEs identified in FortiOS 6.0.x while optimizing NP6lite security processor efficiency.

Exclusively compatible with FortiGate 240D-POE hardware running FortiOS v6.0.12+, this build focuses on mitigating SSL-VPN vulnerabilities and improving threat prevention throughput by 17% through ASIC-accelerated packet inspection. The update aligns with Fortinet’s Q4 2024 security advisory addressing firewall bypass risks in PoE-enabled devices.
