Introduction to FGT_61F-v6-build1364-FORTINET.out.zip
This firmware package (build 1364) delivers critical security enhancements and operational optimizations for FortiGate 61F next-generation firewalls operating on FortiOS v6.4.9. Released in Q2 2025 under Fortinet’s quarterly security maintenance cycle, it addresses 12 CVEs while improving threat detection capabilities for small-to-medium businesses managing distributed network infrastructures.
Exclusively compatible with FortiGate 61F hardware platforms, this update requires devices running FortiOS v6.4.0 or newer. Network administrators in retail and healthcare sectors should prioritize deployment due to PCI-DSS 4.0 compliance upgrades and enhanced medical IoT device visibility features.
