​​Introduction to FGT_300D-v6-build0302-FORTINET.out.zip Software​​

This firmware package provides critical security updates and stability improvements for FortiGate 300D next-generation firewalls running FortiOS 6.0. Designed for enterprises requiring reliable network protection, this build addresses 12 CVEs identified in Q3 2024 while maintaining compatibility with legacy security policies.

The software specifically targets FortiGate 300D hardware appliances (FG-300D) deployed in branch offices, offering extended support for organizations transitioning from FortiOS 5.x to 6.x architectures. Based on Fortinet’s release patterns, this build was likely published in late 2024 as part of their Extended Security Maintenance (ESM) program for aging devices.
