OT Cybersecurity: How an Energy and Waste Management Operator Strengthened Its Operational Resilience?
OT Cybersecurity: How an Energy and Waste Management Operator Strengthened Its Operational Resilience?
Securing Critical Infrastructure Without Compromising Service Continuity
In the energy and waste management sectors, operational continuity is a major challenge. Any interruption can have a direct impact on service availability, facility security, and industrial performance.
Faced with evolving cyber threats and new regulatory requirements, an operator specializing in energy production and waste-to-energy sought to strengthen the security of its OT (Operational Technology) environment while maintaining the operation of its critical infrastructure. Its goal was to gain complete visibility into its industrial assets, improve anomaly detection, and strengthen its ability to respond to cybersecurity incidents.
Gaining visibility into a complex and interconnected industrial environment
The organisation operated numerous industrial facilities relying on heterogeneous OT systems, connected devices, and multiple communication flows. In this context, having precise visibility into assets and their interactions had become essential for managing cyber risks. In particular, the teams had to address several challenges:
- Identify and map all OT assets on the site.
- Quickly detect abnormal behavior or suspicious events.
- Reduce investigation and remediation times in the event of an incident.
- Meet cybersecurity compliance and governance requirements, particularly in the context of NIS2.
Traditional monitoring tools did not provide a sufficiently detailed view of industrial data flows or take into account the specific characteristics of OT environments.
Implement non-intrusive OT monitoring tailored to operational constraints
To address these challenges, an integrated OT monitoring approach was implemented to continuously monitor industrial communications without disrupting operational processes. Based on specialised OT sensors and a centralised analytics platform, this approach made it possible to map industrial assets and obtain a detailed view of all communication flows.
The detected alerts were then enriched with operational context, enabling teams to:
- Quickly identify the affected equipment.
- Assess the potential impact on operations.
- Prioritise remediation actions.
- Respond appropriately to operational constraints.
The project was carried out in close collaboration with the OT teams and plant operators to ensure seamless integration into the existing industrial environment.
Making OT Cybersecurity a Driver of Business Continuity and Performance
Thanks to this approach, the operator now has better control over its industrial cybersecurity risks and enhanced visibility across its entire OT environment.
Beyond security, the project has improved the teams’ responsiveness to incidents, made operations more reliable, and supported the service continuity objectives specific to critical infrastructure in the energy and waste-to-energy sectors.
OT cybersecurity is now fully integrated into the day-to-day operation of facilities and actively contributes to the organisation’s operational resilience.
