Introduction to FGT_3300E-v6-build1828-FORTINET.out.zip

This critical firmware update (v6-build1828) enhances security and performance for Fortinet’s FortiGate 3300E next-generation firewall, designed for large-scale enterprise network deployments. As part of FortiOS 6.4.5 maintenance release series, this build addresses 9 CVEs identified in Q4 2024 while maintaining backward compatibility with existing security policies.

Exclusively compatible with the FortiGate 3300E chassis systems, the firmware leverages Fortinet’s Security Processing Unit (SPU) technology to deliver 200 Gbps threat inspection throughput – a 15% improvement over previous builds. The filename “FGT_3300E” identifies the target hardware platform, with “v6-build1828” representing the security maintenance release containing cumulative patches.
