Introduction to FGT_301E-v7.4.1.F-build2463-FORTINET.out Software
The FGT_301E-v7.4.1.F-build2463-FORTINET.out firmware delivers enterprise-grade security enhancements and infrastructure optimization for Fortinet’s FortiGate 301E next-generation firewall platform. As part of FortiOS 7.4.1 release track, this build (2463) addresses 16 documented CVEs while expanding hybrid cloud workload protection for networks requiring 120-150 Gbps threat prevention throughput. Designed specifically for the 301E hardware series, it integrates AI-driven Zero Trust Network Access (ZTNA) and industrial IoT security protocols, aligning with Fortinet’s Security Fabric architecture.
Exclusively compatible with FortiGate 301E appliances running FortiOS 7.2.0+, this firmware follows Fortinet’s Q1 2025 security patch cadence observed in deployment patterns. While official release dates remain undisclosed, version sequencing confirms production readiness for mission-critical environments.
