Introduction to FGT_301E-v6-build1778-FORTINET.out

This critical firmware update enhances network security for FortiGate 301E series next-generation firewalls, designed for medium-sized enterprises requiring 20Gbps+ threat inspection throughput. Released through Fortinet’s Q4 2024 security advisory cycle (FG-IR-24-1778), the build1778 revision introduces hardware-accelerated deep packet inspection and enhanced protocol support for distributed enterprise networks.

The firmware targets FG-301E hardware platforms running FortiOS 6.4.x feature set, maintaining backward compatibility with configurations created in FortiOS 6.4.3+ versions. It supports networks managing up to 1.2 million concurrent connections while delivering <2ms latency for business-critical applications like VoIP and video conferencing.
