Introduction to FGT_3815D-v6-build0302-FORTINET.out Software
This enterprise-grade firmware update delivers mission-critical security enhancements and performance optimizations for Fortinet’s flagship FortiGate 3815D next-generation firewall. Designed for large-scale data centers and telecom networks, the build0302 release under FortiOS 6.0.6 addresses severe memory corruption vulnerabilities while introducing hardware-accelerated threat prevention for 100Gbps network environments.
Exclusive to the FortiGate 3815D chassis, this update supports organizations managing hyperscale east-west traffic with requirements for FedRAMP High compliance and encrypted traffic analysis. The firmware maintains compatibility with existing VDOM configurations while introducing enhanced telemetry capabilities for hybrid cloud deployments.
