Introduction to FGT_3980E-v6-build1803-FORTINET.out Software

This firmware package delivers critical updates for Fortinet’s enterprise-grade FortiGate 3980E Next-Generation Firewall, aligning with FortiOS v6.4.15 security and performance standards. Released in Q4 2024 through Fortinet’s Product Security Incident Response Team (PSIRT) channels, it addresses 17 CVEs identified in previous v6.4.x branches while introducing hardware-specific optimizations for the 3980E platform’s NP6XLite security processors.

The build1803 revision specifically targets organizations operating high-density 100GbE network environments, maintaining compatibility with FortiManager v7.4.3+ for centralized policy management. As a maintenance release, it preserves full configuration parity with v6.4.14 while resolving edge-case memory leaks observed in dual-supervisor chassis configurations.
