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

This firmware package delivers FortiOS 7.4.3 for FortiGate 3000F Next-Generation Firewalls, designed for hyperscale data center protection and enterprise network security. Released through Fortinet’s Security Fabric Update Program in Q2 2025, it addresses 19 critical CVEs while introducing hardware-accelerated quantum-safe encryption protocols.

Specifically engineered for the FortiGate 3000F platform (FG-3000F), build 2573 supports chassis-based deployments with dual SPU/DPU modules. The update maintains backward compatibility with configurations from FortiOS 7.2.x series, enabling seamless migration for large-scale network infrastructures.
