Cyber Attacks, Stress Mode and Regulations

Challenges for Operators in Energy Companies

Energy companies are increasingly being made subject to regulatory requirements for their IT infrastructure. At the same time, Industrial Control Systems (ICS) are more vulnerable than ever.

Remote control of energy supply systems and innovative concepts such as smart grid add increasing complexity of network control technology. Large-scale malware attacks, unknown vulnerabilities as well as espionage and hacker attacks specializing on critical infrastructure (CI) defy common IT security strategies.

Cybersecurity From Control Room to Substation

Rhebo enables you to implement a reliable substation level monitoring

Secure Supply by Transparency

The Solution: Gain Digital Clarity and Visibility

In order to control the threats, it is necessary to monitor all communication processes and devices within your network control technology.

Complete network condition monitoring using state-of-the-art industrial anomaly detection creates the decisive visibility of your network communication, as required by standards like ISO 27002 and national IT security laws. They detect anomalies at an early stage facilitating the pro-active prevention of disruptions to your supply security.

  • Gain Comprehensive Event Reporting

    Rhebo Industrial Protector reports and prioritizes in real-time any anomaly and provides full forensic data for in-depth analysis.

  • Comply to Regulations and the ISO 27000 Series

    Rhebo Industrial Protector enables compliance with regulations and standards addressing IT security to establish an effective ISMS.

  • Implement Centralized ICS Monitoring

    Rhebo Industrial Protector supports centralized ICS monitoring via standard interfaces to control room systems, SIEM and other platforms.

Detect Network-Anomalies in Real-Time

ISMS and Defence-in-Depth Strategy for Energy Companies

Rhebo Industrial Protector monitors, analyzes and visualizes all assets and the complete data traffic within your ICS as part of your defense-in-depth strategy. In real-time, the anomaly detection reports any communication of:

  • known and unknown malicious code;
  • professional cyberattacks (advanced persistent threats), internal sabotage and manipulation;
  • technical network errors.

The specific protocol types used in power production and supply networks such as OPC, IEC 60870-5-104, IEC 61850-8-1, DNP3 and their variants are fully supported.


You always have full clarity about potentially harmful communication processes in the ICS. You can react immediately to potential disturbances before the energy supply processes are affected or risk blackouts.
