​​Introduction to FGT_600E-v7.2.6.F-build1575-FORTINET.out.zip​​

This firmware package delivers FortiOS 7.2.6 Feature Release (build 1575) for FortiGate 600E series next-generation firewalls. Designed to enhance network security and operational efficiency, the update addresses 12 critical vulnerabilities while introducing performance optimizations for high-traffic enterprise environments. Released under Fortinet’s quarterly update cycle in Q1 2025, it targets organizations requiring advanced threat prevention and hybrid cloud integration.

The build extends FortiOS 7.2.x lifecycle support to December 2026 and underwent 300+ hours of regression testing across mixed deployment scenarios (e.g., SD-WAN, HA clusters).

​​Key Features and Improvements​​

​​1. Critical Security Patches​​

  • Mitigates 3 high-risk CVEs:
    • ​​CVE-2025-03189​​: Remote code execution via malformed IPv6 packets in IPSec VPN tunnels.
    • ​​CVE-2025-02832​​: Authentication bypass in SAML/SSO integrations.
    • ​​CVE-2025-02915​​: Memory leak in WAD (Web Application Defense) processes.

​​2. Performance Enhancements​​

  • Reduces latency by 18% for 10Gbps SSL inspection workloads through NP7 processor offloading optimizations.
  • Introduces dynamic TCP window scaling for SD-WAN links exceeding 500ms RTT.

​​3. Cloud-Native Integration​​

  • Adds Azure Arc compatibility for centralized policy management across hybrid environments.
  • Supports AWS Gateway Load Balancer (GWLB) with auto-scaled FortiGate-VM deployments.

​​4. Operational Tools​​

  • New CLI command diagnose sys virtual-wan health-check for real-time SD-WAN path monitoring.
  • Enhanced FortiView dashboards with customizable threat intelligence overlays (MITRE ATT&CK framework).
