Introduction to FGT_101E-v6-build1579-FORTINET.out
This firmware update package delivers critical security enhancements and performance optimizations for FortiGate 101E next-generation firewalls under FortiOS v6.4.7. Released in Q4 2024 through Fortinet’s Sustained Engineering Program, build 1579 addresses 9 CVEs while maintaining backward compatibility with existing SD-WAN configurations.
Designed for small-to-medium enterprises, this update focuses on hardening network defenses against modern attack vectors like credential harvesting and zero-day exploits. It specifically targets organizations requiring compliance with PCI-DSS 4.0 and NIST 800-53 Rev6 standards for encrypted traffic inspection.
