Introduction to FGT_400E_BP-v6.M-build2095-FORTINET.out

This firmware update delivers critical security hardening for FortiGate 400E BP (Backplane) series appliances operating in high-density data center environments. As part of Fortinet’s Extended Support Cycle for FortiOS 6.4, build 2095 addresses 18 documented vulnerabilities while maintaining compatibility with distributed security architectures.

Specifically optimized for chassis-based deployments, this release enhances VDOM (Virtual Domain) performance and inter-module communication stability. Network architects managing hyperscale environments will benefit from improved BGP route convergence times and enhanced SSL inspection capabilities.

Key Features and Improvements

​​1. Threat Prevention Upgrades​​

  • Mitigation for CVE-2025-2873 (TCP session hijacking vulnerability)
  • Updated IPS engine with 42 new industrial control system (ICS) signatures
  • Hardware-accelerated TLS 1.3 decryption on NP6 processors

​​2. Infrastructure Optimization​​

  • 25% reduction in VDOM context switching latency
  • Enhanced backplane buffer management for 40GbE interfaces
  • BGP route refresh time improved to <3s for 500k+ routes

​​3. Operational Enhancements​​

  • REST API bulk configuration support for multi-chassis deployments
  • SNMP trap generation for power supply redundancy events
  • FortiManager 7.4+ compatibility for centralized policy deployment
