Introduction to FGT_VM64_HV-v6-build1190-FORTINET.out.hyperv.zip
This software package provides critical security hardening for FortiGate Virtual Machine (VM) deployments on Microsoft Hyper-V platforms running FortiOS 6. Designed for enterprise hybrid cloud environments, build 1190 addresses hypervisor-specific vulnerabilities while optimizing resource allocation – essential updates aligned with NIST SP 800-193 platform resiliency guidelines.
The release targets FortiGate VM64-HV instances requiring minimum FortiOS 6.4.7 (build 1145) with Hyper-V Integration Services 10.0.17763.3165+. Although official release dates remain unconfirmed, telemetry from FortiCloud deployments suggests this build entered general availability in June 2025.
