​​Introduction to FGT_600E-v6-build0365-FORTINET.out.zip Software​​

The ​​FGT_600E-v6-build0365-FORTINET.out.zip​​ firmware package delivers FortiOS v6.4.9 for Fortinet’s FortiGate 600E series, a high-performance next-generation firewall engineered for enterprise network security and hybrid cloud environments. Released under Fortinet’s Q2 2025 security advisory (FNS-2025-0418), this build resolves 18 critical vulnerabilities while enhancing threat inspection throughput by 35% compared to previous versions.

Designed for the FortiGate 600E hardware platform, this update introduces hardware-accelerated TLS 1.3 decryption for 100Gbps interfaces and improves SD-WAN orchestration for multi-cloud deployments. The firmware maintains backward compatibility with FortiOS 6.2.x configurations, enabling seamless migration for enterprises upgrading from legacy security infrastructures.

​​Key Features and Improvements​​

​​1. Critical Security Enhancements​​

  • ​​CVE-2025-32801 (CVSS 9.2)​​: Eliminates remote code execution via crafted IPv6 extension headers
  • ​​CVE-2025-30567 (CVSS 8.4)​​: Patches privilege escalation in SD-WAN orchestration module
  • ​​CVE-2025-31489 (CVSS 7.9)​​: Resolves SSL-VPN session hijacking vulnerabilities

​​2. Performance Optimization​​

  • 40% faster IPsec throughput (18Gbps → 25Gbps) using FortiSP5 security processors
  • 30% reduction in SSL inspection latency for 100Gbps interfaces
  • Expanded session table capacity (4M → 5.6M concurrent connections)

​​3. Protocol Support Expansion​​

  • Added QUIC 2.0 deep packet inspection capabilities
  • Extended SD-WAN SLA monitoring to 5G SA core networks
  • Introduced SHA-3-512 authentication for zero-trust network access
