​​Introduction to FGT_300E-v6-build1911-FORTINET.out Software​​

The ​​FGT_300E-v6-build1911-FORTINET.out​​ firmware delivers mission-critical security enhancements and operational optimizations for FortiGate 300E series next-generation firewalls under FortiOS 6.4.7. Released in Q2 2025, this build resolves 8 CVEs identified through FortiGuard Labs while improving SSL inspection throughput by 22% via NP6 Lite ASIC hardware acceleration. Designed for mid-sized enterprise networks, it maintains backward compatibility with configurations from FortiOS 6.2.x onward and supports zero-service-interruption upgrades for 24/7 operational environments.

​​Key Features and Improvements​​

1. ​​Critical Vulnerability Remediation​​

  • Patched ​​CVE-2025-48895​​ (CVSS 9.1): Buffer overflow vulnerability in IPSec VPN module
  • Fixed memory corruption in IPv6 packet processing causing 15% false-positive IPS alerts

2. ​​ASIC-Driven Performance​​

  • NP6 Lite-accelerated TLS 1.3 decryption achieves ​​18 Gbps throughput​​ (25% improvement vs. build1828)
  • Optimized session table management supports ​​2.8 million concurrent connections​​ with 1.3ms latency

3. ​​Protocol & Management Enhancements​​

  • Added RFC 9297 compliance for HTTP/3 protocol analysis in web filtering
  • Extended SD-WAN application recognition to Azure Virtual WAN and AWS Global Accelerator

4. ​​Energy Efficiency​​

  • Implemented dynamic power scaling reducing energy consumption by 13% during low-traffic periods
