Introduction to FGT_80D-v6-build5207-FORTINET.out
This firmware package provides critical security updates and performance enhancements for FortiGate 80D appliances running FortiOS v6.x. Released as part of Fortinet’s quarterly security maintenance cycle, build 5207 addresses multiple CVEs identified in SSL-VPN services and improves threat prevention capabilities for mid-range enterprise firewall deployments.
Compatible exclusively with FortiGate 80D hardware (P/N FG-80D), this release supports organizations requiring NGFW functionality with 2x 10G SFP+ ports and integrated SD-WAN capabilities. The firmware maintains backward compatibility with configurations from FortiOS 6.0 through 6.4, enabling seamless upgrades for existing deployments.
Key Security and Performance Enhancements
-
