Introduction to FGT_601E-v7.2.3.F-build1262-FORTINET.out

This firmware release (build 1262) delivers enterprise-level security enhancements and performance optimizations for FortiGate 601E series firewalls under FortiOS 7.2.3. Designed for mid-sized enterprises requiring advanced threat prevention, it addresses 18 CVEs identified in Fortinet’s Q1 2025 security advisories while improving operational efficiency for distributed network environments.

Exclusively compatible with FortiGate 601E (FG-601E) appliances, the firmware requires 16GB DDR4 RAM and 256GB SSD storage. Released on March 25, 2025, it supersedes the deprecated 7.2.2 branch with extended technical support through Q3 2027.
