Introduction to FGT_81F-v7.0.2-build0234-FORTINET.out
This firmware update delivers critical security hardening for Fortinet’s mid-range FortiGate 81F Next-Generation Firewall, designed for branch offices requiring 5Gbps+ threat inspection throughput. Released on 2025-03-10, the 7.0.2 build addresses vulnerabilities disclosed in FortiOS 7.0.x branches while optimizing operations for networks requiring NIST SP 800-53 Rev.6 compliance.
The update enhances protection against emerging threats targeting firewall management interfaces, particularly crucial given recent campaigns exploiting exposed FortiGate administrative consoles. Compatible with FortiManager 7.4.6+ for centralized policy management, it introduces hardware-specific optimizations for the NP6XLite security processing ASIC.
