Introduction to FGT_800D-v7.0.13.M-build0566-FORTINET.out.zip

This firmware package delivers FortiOS 7.0.13.M-build0566 for FortiGate 800D enterprise firewalls, addressing 9 critical CVEs disclosed in Q1 2025 while introducing hardware-accelerated threat detection capabilities. Designed for organizations requiring carrier-grade network protection, the update enhances ASIC-based SSL inspection throughput by 27% compared to previous 7.0.x builds.

Exclusively compatible with FortiGate 800D hardware (FG-800D models), this March 2025 release follows Fortinet’s Extended Support Branch strategy, providing 18 months of security patches for legacy deployments. The build number 0566 confirms integration of October 2024’s security patches against CVE-2024-23113 RCE vulnerabilities.
