Introduction to FGT_3960E-v6-build1911-FORTINET.out

This enterprise-grade firmware package delivers FortiOS 6.4.9 for FortiGate 3960E Series hyperscale firewalls, designed for service providers and large enterprises requiring multi-100Gbps threat protection with carrier-grade reliability. Released in Q1 2025, the build resolves 23 CVEs from Fortinet’s security advisories while introducing hardware-accelerated quantum-resistant cryptography modules for next-generation network security.

Optimized for FG-3960E hardware platforms, the firmware enhances NP7 ASIC packet processing efficiency by 38% compared to FortiOS 6.4.8. It supports integration with FortiManager 7.6.4+ for multi-tenant policy management and enables 800Gbps MACsec-encrypted backbone connections for hyperscale deployments.
