Overview
What does the OPC UA Universal Server do?
The OPC UA Universal Server connects to multiple industrial and IT systems, aggregates data from disparate sources, and converts it into a unified OPC UA information model — enabling secure, scalable communication across enterprise IT and OT systems. It can even aggregate other existing OPC UA servers into one address space, and is configured through the SIOTH® graphical builder, no custom code required.
Challenges Addressed by OPC UA Universal Server
Industrial environments struggle with siloed systems, varied protocols and slow, insecure data transfer. Legacy methods complicate digital transformation and obscure real-time insights.
Siloed Data Systems
Inconsistent Data Standards
Slow or Unreliable IT/OT Communication
Security and Compliance Risks
Why Choose OPC UA Universal Server?
Multi-Source Data Collection
Collects data from single or multiple disparate data sources with ease
Universal Protocol Conversion
Converts any industrial or IoT protocol to standard OPC UA
Fast, No-Code Configuration
Built in minutes using SIOTH® configurator — no heavy coding required
Secure & Scalable by Design
Ensures secure, scalable, and optimized for IT-OT-IIoT integration
Connectivity
Connect every protocol through one OPC UA interface
Instead of standing up a separate driver or gateway per system, the OPC UA Universal Server normalizes everything into a single OPC UA address space.

Industrial use cases
Where the OPC UA Universal Server fits
Security
OPC UA security, built in
Security is handled at the protocol level, not bolted on - matching how OT teams already segment plant networks.
Encryption and authentication
All OPC UA sessions use built-in encryption, signing, and certificate-based authentication.
DMZ and Purdue model support
Deploy on the DMZ layer to isolate OT networks when aggregating OT-layer OPC UA servers.
