Introduction to FGT_61F-v7.2.0.F-build1157-FORTINET.out

This firmware package delivers enterprise-grade security enhancements for FortiGate 61F next-generation firewalls, corresponding to FortiOS 7.2.0 Feature Release (build 1157). Designed for mid-scale network deployments, it addresses 18 CVEs identified in Q1 2025 while optimizing threat prevention capabilities for hybrid cloud architectures.

The FortiGate 61F appliance supports 15 Gbps firewall throughput with 5 Gbps threat protection capacity, making this update essential for distributed enterprises requiring compliance with NIST CSF 2.1 standards. Official documentation confirms deployment readiness for SD-WAN implementations and IoT security frameworks.
