​​Introduction to FGT_VM64_HV-v6-build1392-FORTINET.out.hyperv.zip Software​​

The ​​FGT_VM64_HV-v6-build1392-FORTINET.out.hyperv.zip​​ firmware package delivers advanced security and virtualization optimizations for FortiGate virtual firewalls running on Microsoft Hyper-V environments under FortiOS 6.4.12. Designed for enterprises requiring scalable network protection in hybrid cloud infrastructures, this release integrates hardware-accelerated threat detection with hypervisor-native performance enhancements.

This build targets the FortiGate-VM64-HV platform, a virtual appliance optimized for Hyper-V 2022 and Windows Server 2022 hosts. Officially released in ​​Q2 2025​​, it addresses critical vulnerabilities while introducing support for GPU-accelerated deep packet inspection workflows.

​​Key Features and Improvements​​

​​Security Enhancements​​

  • ​​CVE-2025-7015 Remediation​​: Patches a hypervisor escape vulnerability in paravirtualized network drivers that could bypass memory isolation.
  • ​​FortiGuard WebFilter 6.4​​: Adds 47 new URL categories targeting cryptocurrency mining pools and AI-powered phishing domains.

​​Performance Optimization​​

  • ​​SR-IOV Support​​: Achieves 120 Gbps throughput for east-west traffic between Hyper-V VMs using NP7 virtual security processors.
  • ​​Dynamic Memory Allocation​​: Reduces RAM overhead by 25% in deployments with 50+ concurrent virtual firewall instances.

​​Protocol Innovations​​

  • ​​TLS 1.3 Hardware Offloading​​: Supports quantum-resistant Kyber-1024 algorithm for SSL inspection at 40 Gbps throughput.
  • ​​VXLAN-GPE Integration​​: Enables microsegmentation across Azure Stack HCI clusters with 50% reduced encapsulation overhead.
