Introduction to FGT_140E_POE-v6-build0484-FORTINET.out

This firmware release (FGT_140E_POE-v6-build0484-FORTINET.out) delivers critical security patches and hardware optimizations for Fortinet’s FortiGate 140E Power over Ethernet (PoE) series appliances. Designed for small-to-medium branch networks requiring advanced threat prevention, this Q2 2024 update addresses 8 CVEs identified in FortiOS 6.0.x while enhancing NP6lite security processor efficiency.

Specifically developed for FortiGate 140E-POE hardware running FortiOS v6.0.13+, this build resolves vulnerabilities in SSL-VPN portals and improves threat prevention throughput by 16% through ASIC-accelerated packet inspection. The update aligns with Fortinet’s Q1 2024 security advisory addressing firewall bypass risks in PoE-enabled edge devices.
