Introduction to FGT_VM64-v6.M-build2095-FORTINET.out Software

This firmware package (FGT_VM64-v6.M-build2095-FORTINET.out) delivers FortiOS 6.4.15 for FortiGate-VM64 virtual appliances, designed to optimize enterprise network security in virtualized environments. Released under Fortinet’s Sustained Engineering Program in May 2025, this maintenance build targets VMware ESXi 6.7U2+ hypervisors and addresses critical vulnerabilities while enhancing operational stability.

Compatible with FortiGate-VM64 virtual machines, the update supports deployments requiring 100+ Gbps firewall throughput in cloud or hybrid infrastructure. Its development aligns with Fortinet’s quarterly security hardening cycle, ensuring compliance with NIST SP 800-193 resilience standards for virtual network functions.
