Overview

The Honeywell 9202‑ETS‑HN1 NE‑FWMB01 Modbus TCP Firewall is a specialized industrial security appliance designed to protect Modbus TCP communications in distributed control systems (DCS), SCADA, and PLC networks. Built on Eaton’s MTL Tofino™ Industrial Security platform, it provides advanced firewall protection, intrusion prevention, and secure traffic filtering for mission‑critical automation environments.

This firewall is engineered for plug‑and‑protect installation, meaning it can be deployed without disrupting existing control systems or requiring complex configuration. Moreover, its rugged design ensures dependable operation in harsh industrial environments such as petrochemical plants, refineries, and power generation facilities.
