1. Introduction to FGT_500D-v6.M-build2060-FORTINET.out.zip

This critical infrastructure firmware delivers FortiOS 6.4.12 for FortiGate 500D enterprise firewalls, designed to address emerging cyber threats in high-density network environments. Released under Fortinet’s Q2 2025 Security Enhancement Program, build 2060 introduces hardware-accelerated deep packet inspection and enhanced protocol compliance for government-regulated networks.

Engineered for the FG-500D chassis – a 3U rack-mounted system supporting 240 Gbps threat protection throughput – this update maintains backward compatibility with FortiOS 6.2.x configurations while implementing NIST SP 800-207 compliance requirements. The firmware targets enterprises requiring PCI-DSS 4.0 compliance and military-grade encryption standards.

2. Key Features and Improvements
