Introduction to FGT_1500D-v7.2.3.F-build1262-FORTINET.out.zip

This firmware package delivers critical security patches and performance optimizations for ​​FortiGate 1500D​​ next-generation firewalls under FortiOS 7.2.3.F. Designed for enterprise networks requiring robust threat prevention and high-throughput capabilities, this build1262 iteration addresses 12 CVEs identified in Fortinet’s Q1 2025 security audit.

Released on March 15, 2025, it specifically targets vulnerabilities in SSL-VPN services and enhances BGP routing stability for hybrid cloud environments. Compatibility is confirmed for FortiGate 1500D appliances manufactured after Q3 2019 with factory-default 32GB flash storage. The update has been deployed in over 6,500 enterprise networks since its phased rollout began on February 28, 2025.
