​​1. Introduction to FGT_3401E-v6-build1112-FORTINET.out.zip Software​​

The FGT_3401E-v6-build1112-FORTINET.out.zip firmware package delivers critical security updates and performance enhancements for Fortinet’s FortiGate 3401E series next-generation firewall platforms. Designed for enterprise data center deployments, this build (1112) under FortiOS 6.2.4 resolves 9 CVEs documented in Fortinet’s Q3 2024 security advisories. The update specifically targets network administrators managing high-density 100Gbps environments requiring FIPS 140-3 compliant encryption.

This firmware maintains backward compatibility with FortiOS 6.0.x configurations while introducing improved VDOM resource management for multi-tenant architectures. Primary deployment scenarios include hyperscale SSL inspection and IPsec VPN concentrator operations.
