1. Introduction to FGT_2200E-v7.2.6.F-build1575-FORTINET.out

This firmware release delivers FortiOS 7.2.6.F for the FortiGate 2200E series, a high-performance enterprise firewall designed for hyperscale data centers and service providers requiring 100Gbps+ threat protection throughput. Released in Q3 2025 under Fortinet’s Feature Release (F-build) track, it resolves 15 CVEs from Fortinet’s 2025 Q2 security advisories while introducing hardware-specific optimizations for the 2200E’s NP7XL security processors.

The 7.2.6.F-build1575 version enhances virtual domain (VDOM) management scalability and implements quantum-safe cryptography for IPsec VPN tunnels. Compatible with FortiManager 7.8.3+ and FortiAnalyzer 7.6.2+, this firmware maintains backward compatibility with SD-WAN configurations from FortiOS 7.0.x deployments.
