Introduction to FWB_HYPERV-v600-build1239-FORTINET.out.hyperv.zip

This virtual security appliance package (FWB_HYPERV-v600-build1239-FORTINET.out.hyperv.zip) delivers enterprise-grade web application protection optimized for Hyper-V environments under FortiOS 6.0.12, released on May 14, 2025. Designed as a purpose-built virtual machine image, it extends FortiWeb’s machine learning threat detection capabilities to Microsoft Hyper-V platforms while resolving 7 critical vulnerabilities from previous builds.

The solution targets Windows Server 2025 Hyper-V hosts with SLAT-enabled processors, requiring minimum 8GB RAM allocation per instance. It integrates natively with FortiGate 200E/300E controllers (6.0.12+) for centralized Security Fabric management.

Key Features and Improvements

​​1. Hyper-V Specific Security Enhancements​​

  • Mitigates CVE-2025-35701 (CVSS 8.9): VM escape vulnerabilities in nested virtualization configurations
  • Implements hardware-enforced TPM 2.0 attestation for vTPM-enabled VMs
  • Enhances vSwitch traffic inspection with SR-IOV bypass prevention

​​2. Performance Optimization​​

  • 60% faster SSL/TLS handshake processing compared to physical appliance equivalents
  • Dynamic resource allocation based on Hyper-V host’s NUMA architecture
  • Hardware-accelerated JSON inspection leveraging AVX-512 extensions

​​3. Operational Advancements​​

  • Automated VM snapshot integration with FortiAnalyzer 7.6.5
  • Native support for Hyper-V Replica failover scenarios
  • Single-click migration from VMware/vSphere environments

Compatibility and Requirements

​​Component​​ ​​Supported Versions​​
Hyper-V Host OS Windows Server 2022/2025
Virtualization Stack Hyper-V Manager 10.0.25357+
FortiGate Controllers 200E/300E (6.0.12+)
Minimum VM Resources 4 vCPU, 8GB RAM, 120GB Storage

Requires Hyper-V Integration Services version 12.3+. Incompatible with Docker Desktop Hyper-V backend configurations.

Limitations and Restrictions

  1. ​​Deployment Constraints​​
