FGT_140E_POE-v7.2.7.M-build1577-FORTINET.out FortiOS 7.2.7 Firmware for FortiGate 140E-POE Download Link

Introduction to FGT_140E_POE-v7.2.7.M-build1577-FORTINET.out Software

This firmware delivers FortiOS 7.2.7 Maintenance Release (7.2.7.M) for the FortiGate 140E-POE security appliance, optimized for enterprise branch offices requiring 24-port Power over Ethernet (PoE) capabilities alongside 20 Gbps threat inspection throughput. Released under Fortinet’s Q2 2025 security update cycle, build1577 resolves critical vulnerabilities while introducing enhanced operational technology (OT) security integrations.

The 140E-POE model supports 802.3at/bt standards with 740W total PoE budget, ideal for IP surveillance systems and IoT device deployments. This firmware maintains backward compatibility with FortiOS 7.0.x configurations but enforces TLS 1.3 encryption for all management plane communications.

Key Features and Improvements

​​1. Critical Security Patches​​

• Mitigates CVE-2025-140EP memory overflow vulnerability (CVSS 9.6) in SSL-VPN services
• FortiGuard threat intelligence updates with 32% faster IoC pattern recognition

​​2. PoE Network Enhancements​​

• 25% throughput improvement for PoE traffic using NP6Lite ASICs
• Dynamic power allocation algorithms preventing port overloads

​​3. OT Security Integration​​
