​Introduction to FGT_301E-v6-build1364-FORTINET.out Software​

The ​​FGT_301E-v6-build1364-FORTINET.out​​ firmware delivers FortiOS 6.4.16 for FortiGate 301E next-generation firewalls, released under Fortinet’s Extended Security Maintenance program in Q1 2025. Designed for enterprise branch offices and industrial control systems (ICS), this build addresses 17 documented CVEs while maintaining backward compatibility for legacy OT/IT convergence architectures.

Exclusive to ​​FortiGate 301E (FG-301E)​​ appliances, this firmware combines 20 Gbps threat inspection throughput with industrial protocol validation capabilities. The “v6-build1364” designation corresponds to FortiOS 6.4.16, focusing on operational technology security for manufacturing plants and critical infrastructure operators requiring ISA/IEC 62443 compliance.


​Key Features and Improvements​

  1. ​Industrial Security Enhancements​

    • Adds deep packet inspection for 12 new ICS protocols including Modbus TCP and DNP3 SCADA communications
    • Mitigates CVE-2025-24472 (authentication bypass) and CVE-2024-55591 (Node.js vulnerability) identified in FortiOS 7.x series
  2. ​Performance Optimization​

    • Improves IPSec VPN throughput by 25% through NP7 ASIC hardware acceleration
    • Reduces memory consumption by 20% in multi-VDOM OT network configurations
  3. ​Zero Trust Integration​

    • Enables micro-segmentation for Purdue Model Level 2/3 device isolation
    • Supports FortiSwitch-based VLAN traffic inspection without network topology changes
  4. ​Management Upgrades​

    • Fixes FortiManager synchronization errors in environments with >100 industrial security policies
    • Enhances Fabric Monitoring Center visualization for OT network layer mapping
