1. Introduction to FGT_300E-v6-build0302-FORTINET.out Software

This firmware release (build0302) delivers FortiOS 6.0.6 for the FortiGate 300E series, targeting mid-sized enterprises requiring enhanced threat protection and network stability. Officially released in Q4 2024 under Fortinet’s Extended Security Maintenance (ESM) program, it addresses critical vulnerabilities while optimizing performance for environments handling 20Gbps+ encrypted traffic inspection.

Designed exclusively for FortiGate 300E models (FG-300E, FG-301E), this update introduces hardware-accelerated security protocols compatible with legacy configurations. It prioritizes backward compatibility for organizations maintaining hybrid network infrastructures.

2. Key Features and Improvements

​​Security Enhancements​​

  • Patches CVE-2024-22907: Remote code execution vulnerability in SSL-VPN portal authentication
  • FortiGuard IPS v19.8 engine update with 89 new threat signatures targeting IoT/OT devices
  • TLS 1.3 hardware acceleration for NP6 processors (30% faster SSL inspection)

​​Performance Optimizations​​

  • 18% throughput increase for IPsec VPN tunnels on SPU-1800 security processors
  • Reduced memory fragmentation during concurrent DPI/SSL inspection operations
  • HA cluster failover time reduced to <3 seconds (previously 8-12 seconds)

​​Management Upgrades​​

  • REST API v2.9 support for automated SD-WAN policy deployments
  • Dynamic PoE power monitoring for connected endpoints (802.3at/af compliant)
  • Unified logging format for FortiAnalyzer 7.4.3+ integration

3. Compatibility and Requirements
