Introduction to FGT_1500D-v7.0.12.M-build0523-FORTINET.out

This firmware package delivers critical security updates and performance enhancements for FortiGate 1500D next-generation firewalls, specifically designed for enterprise network edge deployments. Released on May 12, 2025, as part of Fortinet’s scheduled security maintenance cycle, build0523 addresses 17 CVEs identified in previous v7.0.x releases while optimizing resource allocation for hybrid SD-WAN architectures.

The update supports FortiGate 1500D hardware revisions FG-1500D and FG-1500DF (dual power supply variant), requiring a minimum of 16GB RAM and 256GB SSD storage for optimal operation. It maintains backward compatibility with FortiOS 7.0.10+ configurations through automated policy migration tools.

Key Features and Improvements
