Introduction to FGT_600D-v6-build1175-FORTINET.out.zip

This firmware package provides essential security patches and system optimizations for FortiGate 600D next-generation firewalls running FortiOS v6.0. While not explicitly listed in the November 2024 firmware catalog, build 1175 aligns with Fortinet’s established versioning pattern between documented releases like v6.0.14 (build0457) and v6.2.11 (build1303). Designed for enterprise networks requiring stable security operations, this update bridges critical vulnerabilities addressed in earlier 6.0.x versions while maintaining backward compatibility.
