Introduction to FGT_7000E-v7.4.3.F-build2573-FORTINET.out

This firmware package delivers FortiOS 7.4.3 for FortiGate 7000E Next-Generation Firewalls, designed for hyperscale data center protection and carrier-grade network security. Released through Fortinet’s Security Fabric Update Program in Q2 2025, it addresses 21 critical CVEs while introducing hardware-accelerated quantum-resistant cryptography support.

Specifically engineered for the FortiGate 7000E platform (FG-7000E), build 2573 supports chassis-based deployments with quad security processing units (SPUs). The update maintains backward compatibility with configurations from FortiOS 7.2.x series, enabling seamless migration for enterprise networks requiring multi-terabit throughput.
