Introduction to FGT_140E_POE-v7.0.9.M-build0444-FORTINET.out

This firmware delivers critical security enhancements and operational optimizations for the FortiGate 140E-POE series, Fortinet’s compact next-generation firewall designed for small-to-medium businesses and branch offices requiring Power over Ethernet (PoE) support. Released under Fortinet’s Q2 2025 security advisory cycle, this build introduces improved threat detection for IoT devices and hardware-accelerated traffic inspection for multi-gigabit networks.

​​Supported Hardware​​:

  • FortiGate 140E-POE (FG-140E-POE) with integrated NP4 security processors
  • Models with 16x PoE+ ports (IEEE 802.3at compliant)

The “v7.0.9.M-build0444” designation indicates a maintenance release (M-build) with extended validation for environments requiring 24/7 uptime. Version sequencing aligns with Fortinet’s April 2025 security patch cycle.

Core Security & Operational Enhancements
