Introduction to FWB_400F-v700-build0400-FORTINET.out Software
This firmware release (version 7.0.10 build 400) delivers mission-critical security enhancements and operational optimizations for Fortinet’s 400F series next-generation firewalls, designed for enterprise branch offices and mid-sized networks. Officially published on May 10, 2025, it addresses 12 high-risk vulnerabilities identified in FortiOS 7.0.9 while introducing hardware-accelerated zero-trust network access (ZTNA) capabilities.
Optimized for networks requiring up to 50 Gbps threat protection throughput, this update strengthens Security Fabric interoperability with FortiManager 7.6.10+ and introduces AI-driven anomaly detection for IoT devices. Verified compatibility includes FortiGate 400F/401F/440F appliances running FortiOS 7.0.8+ with NP7 ASIC revision D2 hardware.
