Introduction to FGT_3960E-v6-build1778-FORTINET.out

This firmware package (FGT_3960E-v6-build1778-FORTINET.out) delivers FortiOS 6.4.3 for FortiGate 3960E hyperscale security appliances, designed for data center deployments requiring 400+ Gbps threat-protected throughput. Released under Fortinet’s Sustained Engineering Program in Q3 2024, this build resolves 12 critical vulnerabilities while enhancing east-west traffic inspection capabilities.

Exclusively compatible with FortiGate 3960E chassis systems, the update supports organizations managing multi-tenant cloud environments and software-defined data centers. The firmware aligns with NIST SP 800-193 resilience standards and PCI-DSS 4.0 compliance requirements for financial infrastructure protection.
