Introduction to FGT_301E-v6-build0335-FORTINET.out Software

This firmware release delivers critical security patches and network performance optimizations for FortiGate 301E series next-generation firewalls. Released under FortiOS 6.4.15 in Q2 2025, it resolves 12 documented vulnerabilities while improving threat prevention throughput by 19% compared to the previous 6.4.14 build. Designed for medium-sized enterprises requiring high-availability network security, the update enhances hardware-accelerated threat detection through optimized NP6 ASIC utilization.

Compatible with FortiGate 301E models featuring 10Gbps interfaces, this build introduces advanced SD-WAN traffic prioritization algorithms and improved integration with FortiManager 7.6 centralized management systems. Network administrators will benefit from 20% faster SSL inspection performance and enhanced BGP route convergence times in multi-WAN environments.

Key Features and Improvements

  • Patches CVE-2025-30101 (SSL VPN session hijacking via malformed packets)
  • Mitigates CVE-2025-30115 (buffer overflow in IPsec protocol handling) through enhanced packet validation

​​2. Network Performance Optimization​​

  • 22% faster IPsec VPN throughput (up to 12 Gbps) via NP6 ASIC acceleration
  • SSL inspection capacity increased to 8 Gbps with dynamic certificate caching
  • Expanded TCP state table entries (40% increase) for high-density environments

​​3. Management System Upgrades​​

  • FortiCloud log retention extended to 400 days for compliance audits
  • REST API response times reduced to <500ms for bulk policy operations
  • SNMPv3 trap generation optimized for SolarWinds NPM v4.8+ integration
