Introduction to FGT_3960E-v6-build1723-FORTINET.out

This firmware release (build 1723) delivers mission-critical security enhancements for FortiGate 3960E series appliances operating in hyperscale enterprise networks. As part of FortiOS 6.4’s Extended Security Maintenance branch, it resolves 19 CVEs identified in previous builds while introducing hardware-optimized threat prevention capabilities for 100Gbps+ network environments.

Specifically engineered for FG-3960E hardware platforms (3960E/3960E-XL models), this update supports hyperscale VDOM configurations with 48% faster policy processing compared to v6-build1709. Released on April 30, 2025, it requires 256GB SSD storage and 512GB RAM for full feature deployment.


Core Security & Performance Upgrades
