Introduction to FGT_100EF-v6.M-build2093-FORTINET.out.zip

The FGT_100EF-v6.M-build2093-FORTINET.out.zip firmware delivers enterprise-grade security updates and hardware optimization for FortiGate 100EF series next-generation firewalls. Released under FortiOS 6.4.18 (Q2 2025), this build addresses 21 critical CVEs while enhancing operational stability for small-to-medium business networks.

Designed for FG-100EF hardware platforms manufactured post-Q4 2022, this release maintains backward compatibility with FortiManager 7.0.15+ and implements NIST SP 800-208-compliant cryptographic standards. The update integrates 16 months of cumulative security patches since FortiOS 6.4’s initial release, including enhancements for STP protocol stability observed in network configurations.
