Introduction to FGT_3200F-v7.4.3.F-build2573-FORTINET.out.zip Software
This firmware package delivers FortiOS 7.4.3 for the FortiGate 3200F Series, a hyperscale data center firewall platform designed to handle 387 Gbps firewall throughput with energy efficiency 72% better than industry competitors. Released in Q1 2025, build 2573 addresses 11 critical CVEs while introducing quantum-safe encryption and AI-driven threat intelligence enhancements. The 3200F series targets enterprises requiring multi-100Gbps security performance with 400GE interface support.
Compatibility extends to all variants of the 3200F hardware platform (FG-3200F, FG-3200F-DC) running FortiOS 7.2 or later. This update resolves vulnerabilities including SSL-VPN session hijacking risks identified in Fortinet’s 2025 Q1 security advisories.
