European SCADA Systems compared
SCADA systems monitor and control industrial processes in real time, letting manufacturers, utilities and logistics operators track equipment, collect data and automate responses across plants or networks. The tools differ in protocol support, deployment model and target environment: some focus on heavy industrial automation with PLC integration, others on lightweight dashboards for logistics or building management, and deployment ranges from cloud to on-premise with varying degrees of custom logic support.
European buyers in regulated sectors will check where the data resides and who can access it, as these systems often handle sensitive operational or employee data subject to GDPR. The market includes platforms built for discrete manufacturing, continuous process industries and infrastructure monitoring, each with distinct integration needs and scalability profiles.

What to look for
Protocol coverage
Check which industrial protocols (Modbus, OPC UA, S7, etc.) the system supports natively. Wider coverage reduces the need for middleware or custom drivers.
Deployment options
Evaluate whether the system offers cloud, on-premise or hybrid deployment. On-premise is critical for air-gapped or high-security environments.
Integration depth
Assess how deeply the SCADA system integrates with ERP, MES or PLC systems. Tight coupling reduces manual data entry and errors.
Data residency and access
Confirm where the data is stored and who can access it. Regulated industries require clarity on server location and compliance with GDPR.
Frequently asked questions
What does a SCADA system actually do?
A SCADA system collects real-time data from sensors and devices, monitors equipment status and controls industrial processes automatically or via operator input. It is used in manufacturing, utilities and logistics to improve efficiency, reduce downtime and ensure safety.
Which SCADA systems support SAP integration?
Peakboard offers certified SAP S/4HANA integration, making it a strong choice for manufacturers and logistics operators using SAP for ERP or MES. zenon also integrates with SAP NetWeaver, while atvise® focuses on OT protocols like OPC UA and Modbus rather than direct ERP connectors.
Are there SCADA systems with a free plan?
None of the European SCADA systems in our directory offer a free plan. zenon, Peakboard and atvise® are all commercial products with paid licensing models.
Can I self-host a SCADA system?
Yes. zenon, Peakboard and atvise® all offer on-premise or self-hosted deployment options, which is critical for environments requiring full control over data and infrastructure.
How does zenon compare to Ignition?
zenon is a European SCADA platform with deep industrial protocol support (300+ protocols) and IEC 61131-3 compliant logic, making it a strong fit for complex automation tasks. Ignition is a US-based tool known for its modular architecture and cross-platform support. zenon offers on-premise deployment and integrates with systems like SAP NetWeaver and PI System, whereas Ignition’s deployment and integration focus differs.
Which SCADA systems are hosted in the EU?
Peakboard explicitly offers EU hosting. zenon and atvise® do not have established EU hosting in our current facts, so buyers requiring guaranteed data residency in the EU should verify this directly with the vendor.
What integrations does Peakboard support?
Peakboard integrates with SAP (SAP S/4HANA certified), OPC UA, Siemens S7 PLCs, MQTT, REST API, Excel, SQL databases, ERP systems, MES systems and other SCADA systems. It also supports SSO in its enterprise plan.
Do European SCADA systems comply with GDPR?
Compliance depends on the vendor’s data handling practices and server location. Peakboard offers EU hosting, which aligns with GDPR requirements for data residency. Buyers should confirm DPA availability and server location with each vendor, as these are not uniformly guaranteed.
Is atvise® suitable for building management systems?
Yes. atvise® supports protocols like BACnet, KNX and Modbus TCP, which are commonly used in building management systems. Its web-based approach also makes it accessible for monitoring and controlling building automation from standard browsers.
What is the difference between SCADA and MES?
SCADA systems focus on real-time monitoring and control of industrial processes, while MES (Manufacturing Execution Systems) manage and optimize production workflows, tracking orders, schedules and quality. SCADA provides the data; MES uses it to coordinate manufacturing operations. Tools like Peakboard can integrate with both.
