Introduction to FAZ_800G-v7.2.3-build1405-FORTINET.out Software

This firmware package (build 1405) delivers critical updates for FortiAnalyzer 800G series appliances, designed to enhance log analytics, threat correlation, and compliance reporting capabilities. Released on May 12, 2025, version 7.2.3 addresses 19 security vulnerabilities while introducing performance optimizations for large-scale Security Information and Event Management (SIEM) deployments.

Compatible exclusively with FortiAnalyzer 800G/F models (FAZ-800G, FAZ-800F, FAZ-800G-DC), this update aligns with Fortinet’s Security Fabric architecture to process 2.1 million logs per second (LPS) with 85% reduced storage overhead through enhanced data deduplication algorithms.
