​​Introduction to FGT_3400E-v7.4.4.F-build2662-FORTINET.out.zip​​

The ​​FGT_3400E-v7.4.4.F-build2662-FORTINET.out.zip​​ firmware package delivers FortiOS 7.4.4 for FortiGate 3400E series next-generation firewalls, optimized for hyperscale data centers and enterprise networks requiring 397 Gbps firewall throughput. Released in Q2 2025, this version addresses critical vulnerabilities while introducing quantum-safe encryption readiness and enhanced AI-driven threat prevention.

Designed for FortiGate 3400E/3401E models with 64 GB RAM and 1 TB SSD storage, this build supports hybrid cloud architectures with 100GE QSFP28 interfaces and redundant power supplies. It maintains backward compatibility with FortiOS 7.2.x configurations but requires fresh installations for systems running versions older than 7.0.

​​Key Features and Improvements​​

​​1. Security Enhancements​​

  • ​​CVE-2025-32756 Mitigation​​: Patches a zero-day vulnerability affecting FortiVoice, FortiMail, and FortiNDR devices (CVSS 9.6).
  • ​​Quantum-Resistant VPN​​: Implements hybrid post-quantum cryptography (PQC) algorithms for IPsec VPN tunnels.

​​2. Performance Upgrades​​

  • ​​140 Gbps Threat Protection​​: Achieves 44,000 Mbps IPS throughput with full threat detection enabled, a 22% improvement over FortiOS 7.4.3.
  • ​​Energy Efficiency​​: Reduces power consumption to 312W average (470W max) through dynamic ASIC clock scaling.

​​3. Operational Improvements​​

  • ​​HTTP/3 Visibility​​: Full decryption and policy enforcement for QUIC protocol traffic.
  • ​​AI-Driven Analytics​​: FortiGuard AI now correlates threats across FortiAnalyzer and third-party tools like Microsoft Sentinel.
