Introduction to FGT_3800D-v6-build1723-FORTINET.out Software

The ​​FGT_3800D-v6-build1723-FORTINET.out​​ firmware package delivers critical security enhancements and network optimizations for Fortinet’s enterprise-grade ​​FortiGate 3800D​​ series appliances. As part of the FortiOS 6.4 branch, this build (1723) addresses 14 documented vulnerabilities while enhancing data center deployment capabilities. Designed for high-availability environments requiring 100Gbps+ throughput, it integrates with FortiManager 7.0+ ecosystems and introduces hardware-accelerated threat prevention for hyperscale networks.

Compatible exclusively with ​​FortiGate 3801D/3802D​​ hardware models, this update resolves multiple CVEs identified in FortiGuard Labs’ 2024 threat analysis reports. The firmware maintains backward compatibility with Security Fabric architectures while introducing experimental support for post-quantum encryption algorithms.

Key Features and Improvements
