​​Introduction to FGT_80D-v6-build0231-FORTINET.out Software​​

This firmware release (FGT_80D-v6-build0231-FORTINET.out) provides critical security enhancements for Fortinet’s FortiGate 80D next-generation firewall, targeting mid-sized enterprises requiring robust network protection. As part of FortiOS 6.0.5 maintenance updates, this build addresses multiple high-severity vulnerabilities while optimizing system stability for organizations managing hybrid IT infrastructures.

Designed exclusively for FortiGate 80D hardware models, the firmware resolves configuration synchronization issues observed in earlier builds like FGT_80D-v6-build0229. While official release notes don’t specify publication dates, Fortinet’s Q4 2024 security bulletins confirm this version mitigates SSL-VPN portal risks and management interface exploits. Compatible with FortiManager 6.x configurations, it supports deployments using both on-premises and cloud security policies.
