1. Introduction to FGT_1200D-v7.2.3.F-build1262-FORTINET.out

This firmware package delivers critical security hardening and operational optimizations for the ​​FortiGate 1200D​​ series, an enterprise-grade firewall designed for hyperscale data centers and service provider networks. As part of FortiOS 7.2.3 (build 1262), it resolves 15 documented vulnerabilities while enhancing NP6XLite security processing capabilities for environments requiring >40Gbps threat inspection throughput.

Specifically engineered for carrier-class deployments, this update supports 100GE QSFP28 interfaces with hardware-accelerated TLS 1.3 decryption. Compatible exclusively with hardware serial numbers beginning with ​​FG1200D​​, it requires 64GB DDR5 RAM and 512GB SSD storage to maintain session tables for >10M concurrent connections. Release notes indicate priority deployment for networks handling financial transactions or healthcare data.
