Best Sectra Network Logging and Analysis for Critical IT/OT Systems Alternatives & Competitors in 2026

MBsecure+ is a hardware gateway that provides physical isolation between industrial control system (PLC) networks and HMI application servers. It acts as a hardware bridge between two Linux units, acquiring PLC data over TCP/IP and relaying it to the HMI without establishing a physical link between the PLC and HMI network. Isolation occurs at OSI Layer 1&2 without relying on CPU, software, or IP addressing, preventing direct network access to the PLC from the HMI side. The device supports multiple SCADA/ICS communication protocols used across industries such as energy, water, oil and gas, automotive, transportation, and petrochemicals, including Modbus RTU, Syslog, MQTT, and SMTP, with OPC DA/UA, DNP3, and BACnet planned for future releases. It supports up to 247 Modbus devices per unit and multiple HMI units, with configurable access restrictions via an HMI list. Access to the unit itself is secured through HTTPS with encryption keys. The hardware includes dual RJ-45 CAT6 ports, no fans or disk drives, DIN rail mounting, and supports high availability through unit redundancy. Core use case: interconnecting network segments with different security classifications (e.g., PLC/OT network and HMI/IT network) while eliminating the ability for devices on the HMI network to directly access or hack the PLC.</description> <parameter name="summary">Hardware gateway isolating PLCs from HMI networks while relaying SCADA/ICS protocol data
