Introduction to FGT_140E_POE-v6-build0457-FORTINET.out
This firmware package provides critical security updates and performance enhancements for Fortinet’s 140E-POE series next-generation firewalls. Released under FortiOS 7.6 branch on March 25, 2025, it resolves 14 documented vulnerabilities while optimizing Power over Ethernet (PoE) management capabilities for network edge deployments.
Designed for medium-sized enterprises and distributed campuses, this build supports advanced threat protection features including SSL inspection and intrusion prevention. It maintains backward compatibility with configurations created in FortiOS 7.4.x while introducing new API endpoints for automation workflows.
