​​Introduction to FGT_100EF-v7.2.4.F-build1396-FORTINET.out​​

This firmware package delivers critical security enhancements and performance optimizations for Fortinet’s FortiGate 100EF series next-generation firewalls. Released under FortiOS 7.2.4’s extended support framework in Q1 2025, it addresses 12 CVEs identified in Fortinet’s Q4 2024 Security Advisory. Designed for enterprise branch office deployments, it integrates NP6XLite security processing acceleration with zero-trust network access controls, achieving 20% faster threat inspection throughput compared to previous 7.2.x versions.

Specifically developed for FortiGate 100EF hardware platforms (including 100EF and 100EF-POE variants), this build requires FortiManager 7.4.3+ for centralized policy management. It maintains backward compatibility with FortiOS 7.0 configurations while introducing enhanced TLS 1.3 inspection capabilities for encrypted traffic analysis.
