Introduction to FAZ_3700F-v7.2.4-build1460-FORTINET.out

Fortinet’s ​​FAZ_3700F-v7.2.4-build1460-FORTINET.out​​ firmware package delivers critical updates for the FortiAnalyzer 3700F series, designed for hyperscale security analytics operations. Officially released on March 18, 2025, this maintenance build (1460) under FortiOS 7.2.4 introduces hardware-specific optimizations for environments requiring real-time threat correlation across 50,000+ concurrent devices.

The firmware targets organizations managing multi-petabyte log datasets with mandatory retention periods under regulations like GDPR Article 35 and NIS2 Directive. It enhances interoperability with FortiGate 3700F/4800F NGFWs and FortiManager 7.2.x deployments through improved Security Fabric synchronization.
