​​Introduction to FGT_1500D-v6-build0932-FORTINET.out.zip​​

This firmware package delivers critical security enhancements for Fortinet’s ​​FortiGate 1500D​​ high-performance firewall, specifically designed for enterprise data centers requiring ultra-low latency and high throughput. As part of the FortiOS 6.4 branch (v6.4.3), build 0932 focuses on protocol hardening and operational stability for networks handling mission-critical workloads.

Compatible exclusively with FortiGate 1500D hardware platforms, this release aligns with Fortinet’s Q2 2024 security maintenance cycle. While exact release dates aren’t publicly documented, build numbering conventions indicate deployment readiness for production environments since June 2024. The update maintains backward compatibility with FortiManager 6.4.x and FortiAnalyzer 7.0.x for centralized security management.
