​​Introduction to FGT_300D-v6-build0932-FORTINET.out Software​​

This firmware update provides critical security enhancements and SD-WAN performance improvements for FortiGate 300D series firewalls running FortiOS v6.0. Released under Fortinet’s Extended Security Maintenance program in Q1 2025, build0932 addresses 14 vulnerabilities identified in previous versions while optimizing enterprise network operations.

Designed for branch office deployments, the firmware maintains compatibility with FortiGate 300D hardware (FG-300D) manufactured between 2020-2024. It integrates with FortiManager v7.4+ centralized management systems and supports hybrid deployments with third-party SD-WAN solutions.
