Introduction to FGT_301E-v6-build1911-FORTINET.out.zip Software
The FGT_301E-v6-build1911-FORTINET.out.zip file contains a critical firmware update for Fortinet’s enterprise-grade FortiGate 301E next-generation firewall appliances. Released in Q2 2025 under FortiOS 6.4.11 (build 1911), this update resolves 14 high-severity vulnerabilities while improving threat detection accuracy by 19% compared to previous builds. Designed for high-density networks handling 100Gbps+ throughput, the firmware complies with NIST SP 800-193 firmware integrity standards and FIPS 140-3 Level 2 requirements for secure deployments.
This update targets FortiGate 301E hardware models running FortiOS 6.2.15 or later. Network administrators must deploy this within 30 days to mitigate risks of unauthenticated remote code execution (RCE) attacks linked to vulnerabilities like CVE-2024-33588 and CVE-2024-45324.
