Water Sewage Cyber Security

OT Security For The Water & Waste Water Sector

Threat & Intrusion Detection System for critical infrastructure OT
  • Detect multi-stage cyber attacks in real-time

    … through complete visibility of all OT assets and communication.

  • Mitigate cyber incidents fast and effectively

    … through real-time anomaly detection and notification with all forensic data.

  • Secure water operations 24/7

    … through immediate actionability and professional support by Rhebo experts.

Water quality needs cybersecurity

The water and waste water sector is critical for society, the economy as well as the health of people and the environment. The advancing digitization and process automation optimize operations, but also create new attack surfaces for cyber attacks as well as human error. The near-miss incident at the Oldsmar water utility in Florida, USA demonstrated how quickly water quality can be put at risk. Not only was it sheer luck that nothing worse happened. Because visibility into the OT was lacking, it also remained unclear for two (!) years whether the incident was a cyberattack or internal error.

At the same time, the water sector is struggling with a lack of skilled personnel for operational technology (OT) security, while policymakers and associations are expanding requirements for critical infrastructure.

Trust Build on Expertise

What our customers say
The audit has given us a clearer picture of all processes in our complex industrial control system. This enabled us to analyze all communication traffic extensively and check the ICS specifically for vulnerabilities. We were impressed by the smooth process. The direct development of effective measures optimally prepared us for future cyber security risks.
Falk Richter, Leipziger Wasserwerke Team Leader IT Systems and Applications
Water Sewage Cyber Security
The company supplies 545,000 people with fresh drinking water from five utilities. In addition, 25 sewage plants treat 95,000 m³ of wastewater daily for reintroduction into natural waters.
Rhebo's ICS monitoring system provides us with systematic support in monitoring remote maintenance and remote access points as well as detecting defects and anomalies in the ICS before they cause disruptions in the energy or water supply.
