Air-Gapped Monitoring in the Energy Sector: How PRTG Keeps Isolated OT Networks Visible

To maintain the security of air-gapped energy infrastructure, PRTG Network Monitor utilizes a distributed architecture of remote probes that collect data locally within isolated zones. These probes transmit findings to a central core server via a single, encrypted outbound connection, ensuring comprehensive visibility across substations and generation assets without compromising network isolation. This approach allows operators to monitor critical SCADA and OT systems while remaining compliant with strict security standards like NERC CIP and IEC 62443.
