Introduction to FGT_2500E-v7.2.6.F-build1575-FORTINET.out
The FGT_2500E-v7.2.6.F-build1575-FORTINET.out firmware delivers enterprise-grade security enhancements for Fortinet’s FortiGate 2500E series, designed for hyperscale data centers requiring 300 Gbps threat inspection throughput. As part of FortiOS 7.2.6 Feature Release (build 1575), this update resolves 18 CVEs while introducing hardware-accelerated TLS 1.3 decryption capabilities.
Optimized for networks requiring 99.999% availability, this firmware supports zero-trust segmentation across 25,000+ virtual networks and maintains backward compatibility with FortiOS 7.2.x configurations. The build includes critical patches for vulnerabilities exploited in recent attacks targeting FortiGate management interfaces.
