Introduction to FGT_3960E-v7.2.0.F-build1157-FORTINET.out
This feature release delivers FortiOS 7.2.0 (build 1157) for FortiGate 3960E series next-generation firewalls, designed for hyperscale data centers requiring carrier-grade security and multi-terabit throughput. As part of Fortinet’s 2025 Q1 security enhancement roadmap, this update introduces foundational improvements for zero-trust architecture while maintaining backward compatibility with Security Fabric configurations from FortiOS 7.0.4+.
The 3960E series targets cloud service providers and financial institutions needing advanced threat protection with 40G/100G interface density. Compatible with 3960E and 3960E-DC hardware variants, this firmware became generally available on February 12, 2025 through Fortinet’s phased release schedule.
