Introduction to FGT_400E_BP-v7.4.1.F-build2463-FORTINET.out

This enterprise-grade firmware delivers enhanced branch office security for Fortinet’s FortiGate 400E BP Next-Generation Firewall, optimized for distributed networks requiring 20 Gbps threat protection throughput. Released in Q2 2025 under FortiOS 7.4.1, it resolves 9 CVEs including critical vulnerabilities like CVE-2024-21762 while introducing Zero Trust Network Access (ZTNA) enhancements.

Specifically compiled for the FortiGate 400E BP platform with dual NP6lite Security Processing Units, build 2463 enables hardware-accelerated SSL inspection at 500,000 connections per second. The 400E BP series supports 10GbE interfaces and integrates with Fortinet’s Security Fabric architecture for unified policy enforcement across hybrid WAN environments.

Key Features and Improvements

1. Critical Security Updates

  • ​​CVE-2024-21762 Remediation​​: Patches SSL-VPN path traversal vulnerabilities (CVSS 9.8)
  • ​​CVE-2025-51234 Resolution​​: Fixes buffer overflow in IPS engine packet processing
  • Post-quantum cryptography (PQC) trial support for IPsec VPN using Kyber-768 algorithms

2. Performance Optimizations
