1. Introduction to FGT_3600E-v7.2.3.F-build1262-FORTINET.out
This firmware package delivers critical security hardening and performance enhancements for the FortiGate 3600E series, a hyperscale next-generation firewall engineered for enterprise data centers and service provider networks. As part of FortiOS 7.2.3 (build 1262), it resolves 12 documented vulnerabilities while introducing hardware-accelerated threat protection for 100GE network environments.
Designed for environments requiring >80Gbps threat inspection throughput, this update supports NP7 security processing engines with TLS 1.3 decryption offloading. Exclusive compatibility with hardware serial numbers beginning with FG3600E requires 128GB DDR5 RAM and 1TB SSD storage to maintain session tables for >20M concurrent connections.
