Introduction to FGT_5001D-v6-build1966-FORTINET.out Software

This firmware update addresses critical vulnerabilities identified in Q1 2025 penetration testing audits for FortiGate 5001D hyperscale firewalls. Designed for enterprise networks managing 100-150Gbps traffic loads, build1966 introduces hardware-accelerated quantum-resistant encryption protocols while maintaining backward compatibility with FortiOS 6.4 infrastructure.

Certified for all 5001D chassis configurations (P/N: FG-5001D-xxxx series), the firmware requires 16GB free storage and 64GB RAM minimum. Release notes confirm deployment across hyperscale data centers since its March 2025 security maintenance release cycle.
