​​Introduction to FGT_3980E-v7.0.15.M-build0632-FORTINET.out​​

The ​​FGT_3980E-v7.0.15.M-build0632-FORTINET.out​​ firmware package delivers critical security hardening and infrastructure optimization for Fortinet’s high-performance FortiGate 3980E series next-generation firewalls. Released as part of FortiOS 7.0’s maintenance cycle (build 0632), this update enhances threat prevention capabilities for hyperscale data centers and service provider networks requiring carrier-grade throughput up to 1.2 Tbps.

Designed for enterprise-core deployments, the 3980E series integrates AI-driven security services with SD-WAN orchestration. The “M” designation confirms this build prioritizes vulnerability remediation over feature additions, requiring FortiManager 7.4+ for centralized policy management.
