Introduction to FGT_2601F-v7.2.4.F-build1396-FORTINET.out
This firmware package delivers mission-critical security updates and performance enhancements for Fortinet’s FortiGate 2601F series next-generation firewalls. Released under FortiOS 7.2.4’s extended support framework in Q1 2025, it addresses 9 high-severity CVEs identified in Fortinet’s Q4 2024 Security Advisory. Designed for hyperscale enterprise networks and data center deployments, the build integrates NP7 security processing acceleration with zero-trust network access controls, achieving 28% faster threat detection throughput compared to previous 7.2.x versions.
Exclusively compatible with FortiGate 2601F hardware platforms (including 2601F and 2601F-POE variants), this firmware requires FortiManager 7.4.3+ for centralized policy management. It introduces quantum-resistant encryption protocols while maintaining backward compatibility with FortiOS 7.0.x configurations.
