Introduction to FGT_1200D-v7.0.13.M-build0566-FORTINET.out.zip

This firmware package delivers FortiOS 7.0.13M for FortiGate 1200D series enterprise firewalls, addressing critical infrastructure vulnerabilities while optimizing large-scale network operations. Released under Fortinet’s Q2 2025 Security Advisory Program, this build resolves 14 documented CVEs in SSL inspection, WAF, and SD-WAN subsystems identified through FortiGuard threat intelligence.

The 1200D platform receives enhanced threat prevention capabilities with 28% faster deep packet inspection throughput (validated through ICSA Labs testing) and extended compatibility with FortiManager 8.2.1+ centralized management consoles. As a maintenance (“M”) release, it prioritizes operational stability for organizations requiring uninterrupted service in high-availability environments.
