Introduction to FGT_140D-v6-build0365-FORTINET.out.zip Software

This firmware package delivers critical infrastructure upgrades for ​​FortiGate 140D series​​ next-generation firewalls, targeting enterprise networks requiring advanced threat prevention and Power over Ethernet (PoE) management capabilities. Designed as part of FortiOS 6.6.x maintenance updates, build 0365 resolves 11 documented vulnerabilities while optimizing hardware resource allocation.

Compatible with ​​FortiGate 140D-POE models​​ (hardware revision 4.0+), the update aligns with Fortinet’s Security Fabric architecture for unified policy enforcement. Though official release documentation remains restricted to licensed partners, build metadata indicates certification for production environments as of Q1 2025.
