Introduction to FGT_VM64_AZUREONDEMAND-v6-build1190-FORTINET.out.hyperv.zip
This Azure-optimized virtual machine package delivers critical security updates and cloud performance enhancements for FortiGate Next-Generation Firewall virtual appliances running FortiOS 6.4.15 in Microsoft Azure environments. Released on May 7, 2025, it resolves 4 CVEs identified in Fortinet’s Q2 2025 cloud security advisory while improving east-west traffic inspection efficiency by 27% compared to previous builds.
Designed for Azure Virtual Network deployments, the update supports Dv3-series VMs with 8+ vCPUs and 32GB+ RAM configurations. It maintains backward compatibility with FortiOS 6.4.x cloud deployments but requires Azure Gen2 VM templates for proper initialization.
