Introduction to FGT_2200E-v7.4.4.F-build2662-FORTINET.out

The FGT_2200E-v7.4.4.F-build2662-FORTINET.out firmware package delivers enterprise-grade security enhancements for Fortinet’s 2200E series next-generation firewalls, specifically designed for high-performance network environments requiring 200Gbps+ threat inspection throughput. Released under FortiOS 7.4.4’s Q3 2025 security maintenance cycle, this build resolves 9 CVEs identified in Fortinet’s June 2025 security advisories, including critical vulnerabilities in SSL/TLS 1.3 session resumption protocols and VXLAN segmentation logic.

Optimized for large-scale enterprise deployments, this update supports FortiGate 2200E appliances configured with dual NP7 network processors. The build2662 revision introduces hardware-accelerated threat detection for encrypted traffic flows while improving resource allocation efficiency in multi-VDOM architectures.
