​​Introduction to FGT_1800F-v7.0.12.M-build0523-FORTINET.out Software​​

This firmware release (v7.0.12.M-build0523) provides critical updates for FortiGate 1800F series next-generation firewalls, targeting enterprises requiring high-throughput threat prevention and compliance with modern encryption standards. Designed under FortiOS 7.0 Extended Security Maintenance (ESM), it addresses 14 CVEs disclosed in Q1 2025 while optimizing hardware resource allocation for NP7 security processors.

Compatible exclusively with FortiGate 1800F hardware (models FG-1800F and FG-1801F), this build was officially released on March 15, 2025, with SHA-256 checksum validation to ensure file integrity. It maintains backward compatibility with FortiManager 7.4.5+ for centralized policy management.
