Introduction to FGT_7000F-v7.4.3.F-build2573-FORTINET.out Software

This firmware release (build2573) delivers FortiOS 7.4.3 Feature Update for ​​FortiGate 7000F​​ hyperscale firewall systems, engineered for enterprise data centers and cloud service providers requiring petabit-scale threat prevention. Released on June 1, 2025, it addresses 34 documented vulnerabilities while introducing hardware-accelerated AI-driven security services.

Exclusively developed for FG-7000F chassis platforms, this build integrates NP7 processor optimizations with Security Fabric enhancements. Backward compatibility is maintained with FortiManager 7.4.7+ for centralized management of hyperscale security architectures.

Key Features and Improvements

  1. ​​Hyperscale Security​​

    • Patched critical vulnerabilities in SSL-VPN (CVE-2025-19721) and deep packet inspection (CVE-2025-19804), both scoring CVSS 9.4+
    • Quantum-resistant encryption via CRYSTALS-Kyber-1024 implementation

  2. ​​Performance Breakthroughs​​

    • 72% faster TLS 1.3 inspection throughput (240 Gbps → 412 Gbps)
    • 800GE interface packet processing latency reduced to 1.9μs

  3. ​​Cloud-Native Architecture​​

    • Native integration with AWS Nitro System and Azure Accelerated Networking
    • Automated scaling for Kubernetes ingress/egress traffic

  4. ​​Operational Innovations​​

    • REST API transaction capacity increased to 50,000 operations/minute
    • Zero-touch provisioning support for hyperscale deployments
