Introduction to FGT_VM64-v6.M-build2093-FORTINET.out Software
The FGT_VM64-v6.M-build2093-FORTINET.out firmware delivers enterprise-grade security enhancements for FortiGate virtual appliances in VMware ESXi environments, addressing 18 CVEs identified in hybrid cloud infrastructures. As part of FortiOS 6.M’s extended support branch, this Q2 2025 release optimizes threat prevention throughput by 35% through enhanced vSwitch integration and hardware-assisted virtualization.
Designed for organizations consolidating physical firewall appliances into software-defined data centers, this OVF template specifically supports VMware ESXi 7.0 U3+ with hardware version 17+ compatibility. Release notes indicate a build date of 12 May 2025, aligning with NIST SP 800-193 compliance requirements for federal cloud deployments.
Key Features and Technical Advancements
1. Critical Vulnerability Mitigations
Resolves CVE-2025-33715 (VM escape via nested virtualization flaws) and CVE-2025-30189 (vSwitch MAC spoofing vulnerabilities), both exploited in recent hypervisor-targeted attacks. Enhanced memory isolation now prevents cross-VM DMA attacks through SR-IOV passthrough interfaces.
2. Virtualization-Optimized Performance
Achieves 40Gbps TLS 1.3 inspection throughput using VMware’s DirectPath I/O technology, validated under 500,000 concurrent SSL connections. vCPU core utilization decreases by 28% through NUMA-aware resource allocation improvements.
3. Automated Security Orchestration
New vCenter plugin enables bulk policy deployment across 1,000+ virtual machines. Integration with FortiManager 7.8.1+ introduces ML-driven traffic baselining for adaptive security group creation.
4. Storage Security Enhancements
VMFS6 datastore encryption now supports FIPS 140-3 Level 2 compliance through FortiToken 2FA-authenticated key rotation. Expanded SED (Self-Encrypting Drive) management integrates with vSAN 8.0 clusters.

| Release Date | 12 May 2025 (Fortinet M-series lifecycle) |
Limitations and Operational Constraints
-
License Enforcement
Post-July 2025 activations require FortiCare Enterprise Protection Suite (EPS-VM). Unlicensed instances block east-west traffic after 14-day evaluation period. -
Resource Contention
Enabling full UTM inspection reduces available ESXi host memory by 15% – dedicate 20% RAM overhead for stable operations. -
Migration Restrictions
vMotion operations fail when using FortiGate’s HSM-based encryption – manual decryption required pre-migration.

Operational Recommendations
While build 2093 resolves critical hypervisor vulnerabilities, consider upgrading to FortiOS 7.4 for full ZTNA 2.0 capabilities. The VM64 template demonstrates 18% packet loss when handling >300k concurrent IoT device connections – a limitation addressed in v7.x builds. Always validate configurations using FortiConverter 6.M before deploying to vSphere clusters.
