Introduction to FGT_140E_POE-v6-build1303-FORTINET.out Software

This firmware update delivers critical security enhancements and operational optimizations for FortiGate 140E PoE series next-generation firewalls. Released in Q1 2025, build 1303 addresses 7 CVEs rated medium-to-critical severity while maintaining backward compatibility with existing network configurations. Designed for small-to-medium enterprises requiring Power over Ethernet (PoE) capabilities, the FortiGate 140E PoE appliance supports up to 1.5 Gbps threat protection throughput with integrated SD-WAN functionality.

The update specifically targets vulnerabilities in SSL/TLS inspection modules while improving interoperability with FortiManager 6.2+ centralized management systems. Compatible with both standalone and HA cluster deployments, it aligns with NIST SP 800-193 firmware integrity requirements for network edge security devices.
