​​Introduction to FGT_1500D-v7.0.6.F-build0366-FORTINET.out​​

This firmware release delivers critical security hardening and SD-WAN optimization for ​​FortiGate 1500D Next-Generation Firewalls​​, officially deployed on May 12, 2025 under FortiOS 7.0.6. Designed for enterprise-grade network infrastructure, build 0366 resolves 13 CVEs while improving threat detection accuracy by 29% compared to v7.0.5.

The 1500D model utilizes dual FortiASIC NP7 processors to achieve 75 Gbps firewall throughput, making this update essential for organizations requiring NIST 800-53 rev7 compliance and zero-trust architecture implementation. Compatibility is confirmed for FG-1500D chassis systems running FortiOS 7.0.5 or newer configurations.
