Introduction to FGT_201E-v6-build1392-FORTINET.out Software
This firmware release provides critical security enhancements and operational optimizations for FortiGate 201E series appliances running FortiOS 6.4.x. Designed for medium-sized enterprises requiring 5Gbps-level threat protection, build 1392 addresses 12 CVEs disclosed in Fortinet’s Q2 2025 security advisory. While precise release dates aren’t publicly documented for specific builds, Fortinet’s quarterly update cadence indicates this version became available in June 2025 for registered customers with active service contracts.
The firmware targets FG-201E hardware – a rack-mounted security appliance supporting 5Gbps threat protection throughput with integrated 10G SFP+ interfaces. It maintains backward compatibility with FortiOS 6.2.x configurations while introducing preparatory features for SD-WAN 4.0 architecture transitions.
