OPC UA offers built-in security through the use of certificate exchange and point-to-point encryption methodologies. The OPC Unified Architecture (UA) Server Interface for KEPServerEX provides client applications (such as MES and SCADA systems) seamless and secure access to industrial automation data. It is an open standard, and allows the KEPServerEX OPC UA Server Interface to seamlessly connect to OPC UA client applications running on any operating system as well as web-based clients. OPC UA is a modern communications protocol for industrial automation that is increasingly being adopted for data collection and control by traditional on-premises applications and Industrial IoT and Industry 4.0 applications and platforms.
