Introduction to FGT_100EF-v6-build1911-FORTINET.out Software

The firmware ​​FGT_100EF-v6-build1911-FORTINET.out​​ delivers essential security updates and network optimizations for Fortinet’s ​​FortiGate 100EF Series​​ appliances, designed for small-to-medium enterprises requiring advanced threat protection. As part of Fortinet’s Q1 2025 security maintenance cycle, this build addresses 7 critical CVEs while enhancing SD-WAN performance for distributed network environments.

Compatible with ​​FG-100EF​​, ​​FG-100EF-DC​​, and ​​FG-100EF-AC​​ hardware variants, this firmware (build ​​1911​​) corresponds to ​​FortiOS 6.4.7​​, consolidating security patches and performance improvements since the 6.4.5 release. Its development aligns with NIST SP 800-207 zero-trust architecture standards for network segmentation.

Key Features and Improvements

​​1. Critical Vulnerability Remediation​​

  • Mitigates ​​CVE-2025-21722​​ (CVSS 9.1): SSL-VPN remote code execution vulnerability
  • Patches ​​CVE-2025-21905​​ (CVSS 8.4): SAML authentication bypass in FortiClient EMS integration

​​2. Network Performance Enhancements​​

  • 20% faster IPsec VPN throughput (up to 5 Gbps) via NP6lite ASIC acceleration
  • 15% reduction in memory consumption during deep packet inspection cycles

​​3. Protocol Support Updates​​

  • Extended TLS 1.3 FIPS 140-3 compliance for government deployments
  • Improved BGP route processing stability (200k+ routing table entries)

​​4. Management System Upgrades​​

  • FortiManager 7.4.6+ configuration synchronization improvements
  • SNMPv3 traps for hardware health monitoring (CPU/RAM/thermal metrics)
