Introduction to FGT_3980E-v7.2.6.F-build1575-FORTINET.out
This firmware package delivers FortiOS 7.2.6 Feature Release (build 1575) for the FortiGate 3980E hyperscale security platform, engineered for enterprise networks requiring 800Gbps+ threat inspection throughput. Released under Fortinet’s Q2 2025 security maintenance cycle, it resolves 16 CVEs from FG-IR-25-215 advisory while introducing quantum-resistant encryption for hyperscale environments.
Compatible with 3980E chassis manufactured since 2024, the update introduces hardware-isolated VDOM segmentation and expands Microsoft Azure Arc integration. The firmware requires NP8XL-800G ASIC modules for full functionality and maintains backward compatibility with FortiOS 7.0.x configurations through automated policy conversion tools.
