​​Introduction to FGT_3000F-v7.4.3.F-build2573-FORTINET.out.zip​​

The ​​FGT_3000F-v7.4.3.F-build2573-FORTINET.out.zip​​ firmware package delivers FortiOS 7.4.3 for FortiGate 3000F series next-generation firewalls, designed for hyperscale data centers and enterprise networks requiring 397 Gbps firewall throughput. Released in Q2 2025, this update addresses critical vulnerabilities while introducing quantum-safe encryption readiness and enhanced AI-driven threat prevention.

Exclusively compatible with FortiGate 3000F/3001F hardware revisions 05+, 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 pre-7.0 versions.

​​Key Features and Improvements​​

​​1. Security Enhancements​​

  • ​​CVE-2024-23125 Mitigation​​: Patches heap-based buffer overflow risks in deep packet inspection engines, preventing remote code execution attacks.
  • ​​Quantum-Resistant VPN​​: Implements hybrid post-quantum cryptography (PQC) algorithms for IPsec VPN tunnels, future-proofing encrypted communications.

​​2. Performance Upgrades​​

  • ​​397 Gbps Firewall Throughput​​: Maintains industry-leading throughput even with full threat prevention enabled, 7.4x faster than competitors.
  • ​​31 Gbps Threat Protection​​: Enhances AI/ML-driven IPS performance by 22% compared to FortiOS 7.4.2.

​​3. Operational Improvements​​

  • ​​HTTP/3 Visibility​​: Full decryption and policy enforcement for QUIC protocol traffic.
  • ​​Energy Efficiency​​: Reduces power consumption to 312W average (470W max) through dynamic ASIC clock scaling.
