Introduction to FGT_5001D-v6-build1637-FORTINET.out Software

This firmware package delivers FortiOS 6.4.6 for FortiGate 5001D series next-generation firewalls, addressing critical security vulnerabilities while optimizing network performance for large-scale enterprise deployments. Designed for high-throughput environments, build 1637 resolves 19 documented CVEs and introduces hardware offloading enhancements for NP6 processors.

Compatible exclusively with FortiGate 5001D and 5001DF hardware models, this update aligns with Fortinet’s Q3 2024 security advisory cycle (release date: September 18, 2024). It maintains backward compatibility with Security Fabric integrations while hardening SSL-VPN and IPSec protocol stacks against emerging threats.
