OT Security For The Energy 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 energy production and distribution 24/7

    … through immediate actionability and professional support by Rhebo experts.

The new energy sector challenge: cybersecurity

The energy sector faces complex challenges in maintaining basic supply. The need for system integration and decentralization increases the attack surface in an already highly digitally insecure infrastructure.

Meanwhile, critical infrastructure continues to become the focus of strategic and long-term cyberattacks that circumvent common security mechanisms. Additionally, the sector is struggling with a lack of skilled personnel to keep their operational technology (OT) secure, while policymakers are expanding requirements for critical infrastructure operators.

Simple and effective OT security for the energy sector

Detect attacks on your operational technology network

With Rhebo, companies in the energy sector can secure their industrial processes and infrastructures against professional, multi-stage cyber attacks in a targeted manner. We establish complete asset visibility in the OT, identify vulnerabilities, and detect cyber incidents in real time that could put the security, integrity, and availability of critical processes at risk.

Ensure legal and standard compliance

Rhebo solutions comply to and support the security requirements for a thorough security posture laid out in the NIS 2 Directive and specified in the various national legislations. With our OT monitoring, anomaly detection, and security services, we deliver simple, focused, and rapidly integrated solutions to meet the requirements for logging and detecting security-related events in OT, and to ensure rapid response to incidents.

Bridge the OT security resources gap

Rhebo supports its customers along the entire OT security lifecycle – from initial risk analysis, to integration and baselining, to managed OT monitoring with the Rhebo threat and intrusion detection. Thus, companies in the energy sector can thus focus on their core business without losing sight of the security of their critical processes.
