Introduction to FGT_3601E-v7.2.3.F-build1262-FORTINET.out Software

This firmware package delivers critical updates for FortiGate 3601E series next-generation firewalls operating on FortiOS 7.2.3. Designed for enterprise network security infrastructure, build “1262” addresses 18 documented vulnerabilities while enhancing threat prevention capabilities for high-density 100Gbps environments.

Exclusively compatible with FortiGate 3601E hardware platforms, this Q1 2025 release maintains backward compatibility with configurations deployed on FortiOS 7.0.x and later. Security bulletins confirm mitigation of 4 critical CVEs affecting SSL inspection and SD-WAN modules, including CVE-2025-03601 related to authentication bypass risks.
