Introduction to FGT_3601E-v7.2.2.F-build1255-FORTINET.out

This firmware release delivers enterprise-grade security enhancements for Fortinet’s high-performance FortiGate 3600E series firewalls. Designed under FortiOS 7.2.2 architecture, build 1255 addresses 11 critical CVEs while introducing hardware-accelerated threat prevention through upgraded NP7 security processors.

Compatible exclusively with the 3600E platform (models: 3601E, 3603E, 3605E), this update supports hyperscale network environments requiring 400Gbps+ threat inspection throughput. The release aligns with Fortinet’s Q2 2025 security update cycle, though exact publication dates follow enterprise deployment protocols.
