​​Introduction to FGT_80D-v6-build0163-FORTINET.out Software​​

This firmware update addresses critical vulnerabilities and performance optimizations for FortiGate 80D series firewalls, targeting enterprise networks requiring enhanced threat prevention and compliance with modern security standards. Released in Q4 2024 under Fortinet’s Security Fabric framework, build0163 resolves 9 CVEs identified in FortiOS 6.0-6.4 branches while maintaining backward compatibility with legacy configurations.

Designed exclusively for FortiGate 80D hardware appliances, this release focuses on SSL-VPN stability, memory leak fixes in deep packet inspection (DPI) modules, and improved TCP session handling under sustained 10Gbps traffic loads. The update requires FortiOS 6.0.14 or newer as a baseline and 2GB RAM for optimal operation.

​​Key Features and Improvements​​
