Introduction to FGT_401F-v7.0.13.M-build0566-FORTINET.out Software
This firmware package delivers FortiOS 7.0.13 M-Series enhancements specifically engineered for FortiGate 401F next-generation firewall appliances. Released under Fortinet’s Q2 2025 security update cycle (build 0566), it addresses 19 documented CVEs while optimizing threat protection throughput for enterprise branch networks. The “M-Series” designation guarantees extended maintenance support through Q4 2027, making it ideal for organizations requiring long-term operational stability.
Designed for medium-sized enterprises, the firmware enhances the 401F’s NP6 security processor performance while maintaining backward compatibility with existing SD-WAN configurations. It introduces critical security hardening measures for SSL-VPN and IoT device management protocols based on Fortinet’s latest threat intelligence.
