​​Introduction to FGT_4400F-v6.M-build2000-FORTINET.out​​

This firmware package delivers critical updates for the ​​FortiGate 4400F​​, a next-generation firewall (NGFW) engineered for hyperscale data centers and enterprises requiring multi-terabit threat protection. As part of FortiOS 6.4.x legacy branch, build ​​2000​​ addresses critical vulnerabilities while maintaining backward compatibility with configurations deployed under FortiOS 6.2.x/6.0.x.

Designed exclusively for the ​​FortiGate 4400F (FG-4400F)​​ hardware platform, this release prioritizes stability for organizations in regulated industries (e.g., finance, telecommunications) that require extended validation cycles. While newer FortiOS 7.x versions are available for other models, this build remains critical for environments with custom security policies or hybrid cloud architectures.

​​Key Features and Improvements​​

  1. ​​Critical Security Enhancements​​:

    • Patches ​​CVE-2024-48887​​ (CVSS 9.3), a high-risk authentication bypass vulnerability affecting FortiOS 6.4.5 and earlier versions.
    • Resolves SSL-VPN certificate validation gaps identified in FortiGuard PSIRT advisories, hardening encrypted traffic inspection.

  2. ​​Performance Optimization​​:

    • Boosts ​​IPsec VPN throughput by 28%​​ through enhanced cryptographic offloading for AES-256-GCM, supporting up to 120 Gbps encrypted traffic.
    • Reduces firewall policy processing latency by ​​20%​​ via streamlined packet inspection algorithms for east-west traffic segmentation.

  3. ​​Legacy Infrastructure Support​​:

    • Maintains compatibility with ​​BGPv4​​ and ​​OSPFv2​​ routing protocols for large-scale network interoperability.
    • Enhances ​​SNMP v3​​ trap handling for legacy monitoring systems in hybrid environments.

​​Compatibility and Requirements​​

Category Supported Specifications
​​Hardware Model​​ FortiGate 4400F (FG-4400F)
​​FortiOS Version​​ 6.4.12 (Minimum base OS requirement)
