Introduction to FGT_3815D-v6-build0932-FORTINET.out Software
The FGT_3815D-v6-build0932-FORTINET.out firmware package delivers critical security hardening and performance optimizations for Fortinet’s enterprise-class FortiGate 3815D firewall. Designed for hyperscale data center deployments, this FortiOS 6.4.3-compatible build resolves 17 documented vulnerabilities while enhancing east-west traffic inspection capabilities for private cloud environments.
As part of Fortinet’s Security Fabric 6.4 architecture, this firmware (build 0932) focuses on maintaining compliance with NIST SP 800-193 standards and improving threat prevention throughput for 100GbE network interfaces. Official documentation confirms backward compatibility with configurations from FortiOS 6.4.0 onward, enabling seamless policy migration for multi-vendor ecosystems.
Key Features and Improvements

- End of Engineering Support: Q2 2028 (aligned with FortiOS 6.4 lifecycle).
Limitations and Restrictions
-
Hardware Exclusivity
This firmware operates exclusively on FortiGate 3815D chassis with factory-installed NP7 ASICs. Installation attempts on 3815E/3800D models trigger hardware mismatch errors. -
Configuration Constraints
- Virtual domains (VDOMs) exceeding 512 instances require CLI adjustments post-upgrade.
- Custom SSL inspection profiles must be revalidated against FIPS 140-3 standards.
-
Downgrade Protocols
Reverting to versions below 6.4.0 necessitates full system wipe via FortiExplorer recovery mode.
