Introduction to FGT_3600E-v6-build0387-FORTINET.out
This firmware package delivers critical updates for Fortinet’s FortiGate 3600E next-generation firewall, a high-performance solution designed for large-scale enterprise and data center environments. As part of FortiOS 6.4.15 under the Long-Term Support (LTS) branch, build0387 addresses 9 documented vulnerabilities while optimizing hardware resource utilization for networks requiring 10Gbps+ threat inspection throughput.
Exclusively compatible with the FortiGate 3600E chassis, this release enhances integration with Fortinet’s Security Fabric ecosystem, including centralized policy management via FortiManager 7.4.6+ and real-time analytics through FortiAnalyzer 7.2.10+. While the official release date is restricted to licensed partners, build metadata confirms alignment with Fortinet’s Q3 2025 security advisory cycle.
