​​Introduction to FGT_4400F-v7.4.0.F-build2360-FORTINET.out​​

This firmware package delivers FortiOS 7.4.0.F for the FortiGate 4400F series, designed for hyperscale data center security operations requiring 400Gbps+ threat inspection throughput. Released in Q4 2024 under Build 2360, it addresses 18 documented vulnerabilities from Fortinet’s PSIRT advisories while introducing hardware-accelerated threat detection enhancements.

Compatible with FG-4400F and FG-4400F-DC hardware platforms, this update strengthens Security Fabric integration across hybrid cloud environments. It supports Zero Trust Network Access (ZTNA) 2.1 enforcement capabilities and provides backward compatibility with FortiManager 7.4.x management systems.

​​Key Features and Improvements​​

    • Mitigates FG-IR-24-019: Fixes SAML/SSO configuration vulnerabilities in multi-tenant deployments.

  2. ​​Performance Enhancements​​

    • Boosts IPsec VPN throughput by 28% via NP7 ASIC hardware acceleration optimizations.
    • Reduces SSL/TLS 1.3 inspection latency to <0.6ms through session resumption improvements.

  3. ​​Zero-Trust Architecture​​

    • Implements dynamic context tags for ZTNA 2.1 application steering policies.
    • Introduces trial support for quantum-resistant encryption using Kyber-1024 algorithms.

  4. ​​Operational Efficiency​​

    • Enables automated configuration drift detection via FortiManager 7.4.3+ integration.
    • Simplifies firmware rollbacks using snapshot-based version comparison tools.
