Introduction to FGT_300E-v6-build0131-FORTINET.out.zip Software
This firmware package delivers critical security enhancements and system optimizations for Fortinet’s FortiGate 300E security appliance, designed for enterprise branch networks requiring extended lifecycle support. As part of FortiOS 6.4.3 (build 0131), it addresses multiple documented vulnerabilities while maintaining backward compatibility with legacy configurations.
The update targets organizations operating FortiGate 300E hardware in distributed corporate environments where hardware refresh cycles are delayed. Exclusive to FG-300E platforms running FortiOS 6.x series, this build provides transitional security coverage until infrastructure modernization projects resume.
