Introduction to FGT_1100E-v7.2.3.F-build1262-FORTINET.out

This firmware release (build 1262) delivers critical security enhancements and enterprise-grade performance optimizations for FortiGate 1100E series firewalls under FortiOS 7.2.3. Designed for large-scale network infrastructures requiring carrier-class security, it resolves 23 CVEs identified in Fortinet’s Q1 2025 security advisories while enhancing threat prevention capabilities for high-traffic environments.

Specifically engineered for FortiGate 1100E (FG-1100E) appliances, the firmware requires 16GB DDR4 RAM and 256GB SSD storage. Released on March 28, 2025, it supersedes the deprecated 7.2.2 branch with extended technical support through Q4 2027.
