1. Introduction to FGT_3300E-v6-build1879-FORTINET.out Software

This firmware package delivers critical security and performance updates for Fortinet’s FortiGate 3300E Next-Generation Firewall, designed for enterprise-grade network infrastructure. Released under FortiOS v6.4.6 framework in Q1 2025, it addresses 12 documented CVEs from previous v6.4.x versions while optimizing hardware acceleration for the platform’s NP6XLite security processors.

Targeting hyperscale data center deployments, build1879 introduces chassis cluster optimizations for models with dual storage controllers. The firmware maintains backward compatibility with FortiManager v7.4.3+ for centralized policy orchestration and supports multi-VDOM configurations up to 500 virtual domains.

2. Key Features and Improvements
