1. Introduction to FGT_3980E-v6.M-build2060-FORTINET.out Software

This firmware release (v6.M-build2060) delivers critical security updates and performance enhancements for FortiGate 3980E hyperscale firewalls, designed for enterprise data centers requiring 400Gbps threat protection throughput. Based on FortiOS 6.4.15, it resolves 12 CVEs identified in Q4 2024 while optimizing SSL inspection latency by 23% compared to prior 6.4.x versions.

Compatible exclusively with FortiGate 3980E hardware revision C (H3) models, this build requires 32 GB RAM and dual 800GB SSD storage for full functionality. Official release occurred on February 28, 2025, with backward configuration compatibility maintained from FortiOS 6.4.12 onward.
