Introduction to FGT_VM64_KVM-v6-build1914-FORTINET.out.kvm.zip
This KVM-compatible virtual machine image delivers FortiOS 6.4.14 for FortiGate-VM64 virtual firewalls, designed for enterprise network security testing and production deployments in virtualized environments. Released on March 12, 2025, the build addresses 11 critical CVEs while introducing enhanced virtualization-specific optimizations for KVM hypervisors.
The software package enables network administrators to deploy Fortinet’s next-generation firewall capabilities in Linux-KVM environments, supporting threat prevention, VPN termination, and SD-WAN orchestration. It is backward-compatible with FortiGate-VM64 instances running FortiOS 6.2.0 through 6.4.13.
