Introduction to FGT_300E-v7.4.2.F-build2571-FORTINET.out.zip

This firmware package delivers FortiOS 7.4.2 for FortiGate 300E series next-generation firewalls, designed to enhance enterprise network security through advanced threat prevention and performance optimization. As part of Fortinet’s Feature Release (F-build) cycle, this version introduces 12+ functional enhancements while maintaining backward compatibility with existing configurations.

Specifically engineered for the 300E hardware platform (FG-300E, FG-301E), the firmware supports 25Gbps threat protection throughput with full UTM inspection enabled. The “F-build2571” designation confirms completion of 60-day lab validation cycles, making it suitable for production deployment after thorough testing.

Key Features and Improvements
