When a PLC stops responding or a link to a substation drops, the question is always the same: is it network, facility, or process? PRTG brings network, utility, and process data together and when something trips, you see the full picture in one place, not separate systems.
After an outage, two questions always follow: what caused it, and how do you show NERC CIP, NIS2, or IEC 62443 regulators that it's addressed? PRTG's OPC UA Server feeds network data into your OT stack, so engineering and compliance both get a documented record of what happened.
NERC CIP, NIS2, and IEC 62443 require continuous visibility into critical assets. PRTG gives you the data compliance reporting depends on with asset inventory, uptime history, and alerting. All ready on demand, without assembling logs manually.
When a device fails, you need to know what's wrong before a technician drives out. PRTG gives remote visibility into switches, networking equipment, satellite links, cellular quality, RTU health, environmental conditions, access control, and CCTV.
When a control room alarm fires, operators need to know which device failed. PRTG feeds alarms into your SCADA so one click shows the specific device or segment behind the problem. No bridging between IT dashboards and SCADA required.
A new device can join the SCADA network with no ticket, no updated documentation, no asset record, and IT is the last to know. PRTG closes that visibility gap without opening a new one, with OT network monitoring thats fully air-gapped where required.
A slow RTU, gaps in historian logs, a stalled SCADA polling cycle. These are often infrastructure problems, not OT problems. PRTG gives control room and SCADA teams visibility into the network and server layer underneath, so odd process behavior comes with an answer.
IT and OT data in a single dashboard — building systems, IT environment, and production, side by side
SNMP sensor data down to individual measurements, like cabinet temperature
Industrial cabinet status at a glance — every component monitored in one view
PRTG supports standard IT protocols and OT protocols, including Modbus, OPC UA, MQTT, SIMATIC S7, all configured to your environment.
See the PRTG Manual for a list of all available sensor types.
Bring IT infrastructure data into the SCADA environment. PRTG's OPC UA Server publishes network switch health, server status, and communication link data to any OPC UA-compatible system your Operations teams use.
Companies around the world trust PRTG Network Monitor when it comes to ensuring that their IT systems run smoothly.
Keeping the Lights On for 3.1 Million People: 300 Substations, One Platform
Adani Electricity supplies power to 3.1 million consumers across 400 square kilometers of Mumbai. With 300 unmanned substations and a 900 km fiber network to monitor around the clock, they needed a solution that could handle SCADA data, optical parameters, and complex alerting at scale. PRTG met every requirement, and keeps expanding as the grid grows.
25,000 Sensors, 900 Sites, One Unified View
ENGIE Solutions provides energy and efficiency services across France, and monitors it all with PRTG. When IoT deployments pushed their setup past 25,000 sensors across data centers, remote sites, and wind turbines, they scaled to PRTG Enterprise Monitor. Today, 63 team members rely on a single consolidated dashboard to stay on top of everything, from server health to connected heating systems.
Solar Parks Across Three Continents: Monitored from One Control Center
GRUPOTEC operates 20 solar parks in Spain, the UK, France, Kenya, and beyond. With strict 99% availability SLAs and industrial controllers to monitor alongside IT networks, they needed more than a standard monitoring tool. PRTG with Modbus compatibility and Business Process sensors gives their team in Spain a single view of power generation and network health across every park, wherever it is.
In Energy companies, the right teams need the right data. Our guide shows how to implement holistic monitoring that brings elements from IT, OT and IIoT into your dashboards.
See how PRTG is used to monitor an energy grid in practice — combining SCADA systems, remote OT devices, and IT infrastructure into one consolidated view. A real-world demonstration with partners, built around the challenges of managing distributed energy infrastructure.
Watch this on-demand webinar to understand where IT and OT monitoring gaps occur — and how a unified approach closes them. Relevant for energy teams managing both control systems and IT infrastructure across distributed sites.
IT manages servers, networks, and applications, while OT manages SCADA, RTUs, PLCs, and field devices — traditionally with little visibility into each other's environment. That blind spot shows up worst during an incident.
PRTG bridges the gap in both directions: IT gains visibility into industrial controllers, while PRTG's OPC UA Server feeds infrastructure data directly into the SCADA dashboards and historians OT already uses, with no new tool required.
Modbus (Modbus RTU Custom and Modbus TCP Custom), OPC UA, MQTT, and SIMATIC S7 - alongside all standard IT protocols (SNMP, WMI, SSH, REST APIs). OT sensors are designed for you to customize them to match your device.
PRTG automatically maintains the asset visibility, uptime history, and threshold event records that NERC CIP, NIS2, and IEC 62443 auditors ask for, making reporting available when you need it, scheduled or on demand
A lightweight monitoring probe deploys at each site, collects data locally, and reports back to your central PRTG core server, with no local IT staff needed to manage it day-to-day. The core server can be deployed on your air-gapped OT network, or your enterprise network, entirely depending on your security requirements.
No. PRTG is agentless, and uses read-only versions of Modbus, OPC UA, MQTT, SNMP. It does not write to or command field devices.
One sensor monitors one measured value. A switch port's traffic, a server's CPU load, or a Modbus register value. Our users typically configure 5–10 sensors per device.
