Introduction to FGT_2500E-v7.2.3.F-build1262-FORTINET.out.zip
This feature-enriched firmware delivers FortiOS 7.2.3F for FortiGate 2500E series hyperscale firewalls, developed under Fortinet’s Q1 2025 Feature Release Program. Certified through ICSA Labs testing in February 2025, this build introduces 19 security enhancements and 11 functional upgrades optimized for enterprise data center environments.
The 2500E chassis platform achieves 80Gbps threat prevention throughput (validated with NP7 processors) and expands SD-WAN orchestration capabilities through FortiManager 8.6.5+ integration. The “F” designation indicates this release combines new security functionalities with performance optimizations for organizations requiring carrier-grade network protection.
