1. Introduction to FAZ_VM64-v7.4.3-build2487-FORTINET.out Software

This critical maintenance release (build 2487) delivers enhanced security and analytics capabilities for FortiAnalyzer virtual machines, specifically optimized for multi-tenant SOC environments. The update aligns with Fortinet’s Q1 2025 security advisory cycle, addressing 12 high-severity vulnerabilities while introducing hardware-accelerated log processing for cloud-native deployments.

Compatible with VMware ESXi 8.0U2+ and KVM hypervisors, this build requires minimum 16 vCPUs and 64GB RAM for production deployments. The “VM64” designation confirms native support for 64TB distributed log storage configurations with AES-256-GCM encryption-at-rest.
