Introduction to FGT_3980E-v7.2.3.F-build1262-FORTINET.out

This enterprise firewall firmware update addresses 7 critical vulnerabilities in FortiGate 3980E next-generation firewalls while optimizing hyperscale network performance for data center edge security deployments. Designed for organizations handling multi-tenant cloud environments, the build resolves memory allocation conflicts observed in VDOM configurations exceeding 40Gbps throughput.

The firmware specifically targets FortiGate 3980E appliances (FG-3980E) running FortiOS 7.2.x, with mandatory installation recommended before Q1 2026 per Fortinet’s vulnerability remediation cycle. Network architects managing financial transaction networks or hyperscale SaaS platforms will benefit from its enhanced TLS inspection capabilities and hardware-accelerated threat prevention.
