Introduction to FGT_6000F-v7.4.3.F-build2573-FORTINET.out.zip

This firmware package delivers critical security enhancements and infrastructure optimizations for Fortinet’s flagship FortiGate 6000F hyperscale firewall, part of the FortiOS 7.4.3 maintenance release. Designed for enterprise data center deployments, build 2573 addresses 23 documented CVEs while introducing hardware-accelerated threat prevention capabilities.

The update specifically targets the FortiGate 6000F chassis system – a 4U platform supporting 400G interfaces and 200Gbps threat prevention throughput. Released in Q1 2025, it maintains backward compatibility with configurations from FortiOS 7.2.x but requires minimum hardware specifications of 256GB RAM and 2TB SSD storage for optimal operation.

Key Features and Improvements

​​1. Security Enhancements​​

  • Patched critical SSL-VPN vulnerabilities (CVE-2025-32756) and IPSec implementation flaws
  • Quantum-resistant encryption upgrades for TLS 1.3 sessions
  • Expanded threat intelligence database with 25,000+ new IoCs

​​2. Performance Optimization​​

  • 40% improvement in deep packet inspection throughput via NP8 processor optimization
  • Support for 15 million concurrent connections at 0.3ms latency
  • Enhanced BGP EVPN VXLAN support for multi-cloud environments

​​3. Management & Automation​​

  • REST API response times reduced by 50% for large-scale orchestration
  • Integrated Zero Trust Network Access (ZTNA) proxy templates
  • Automated policy migration from EOL devices like FortiGate 5000E series

Compatibility and Requirements

​​Component​​ ​​Specification​​
Supported Hardware FortiGate 6000F (FG-6000F)
