Cybersecurity Challenges in the Renewable Energy Sector
Operational Visibility Without Increasing Cyber Risk
- Renewable energy systems rely on continuous OT telemetry and performance data
- Central monitoring and cloud analytics are now essential
- Traditional connectivity approaches can expose critical energy infrastructure to unnecessary risk and disrupt operations
Managing Cyber Threats Across Distributed Renewable Infrastructure
- Offshore and remote assets increase operational dependency on connectivity
- Vendors and third parties require controlled access to operational environments
- Expanding portfolios increase segmentation and trust challenges
Cyber Resilience and Regulatory Expectaction
- Renewable infrastructure is increasingly treated as critical national infrastructure
- Operators must demonstrate stronger cyber resilience and operational assurance
- Security controls must support uptime, scalability and resilience
RENEWABLE OT ENVIRONMENTS
Built to Reinforce Security in the Energy Sector
Designed around the operational realities facing modern renewable environments including distributed infrastructure, remote operations, operational resilience and secure OT to IT connectivity.
Reduce Cyber Risk with Secure Renewable Connectivity
- Assured OT-to-IT and OT-to-cloud data transfer to support interconnectivity in the energy grid.
- Hardware-enforced one-way connectivity using Data Diodes
- High-assurance Cross Domain Solutions for renewable operations
- Policy-enforced inspection and filtering of OT data
- Secure integration with SCADA, historians and analytics platforms
- Deterministic and resilient data transfer between segregated networks
- Support for legacy operational technology and industrial control systems
- Reduced cyber attack exposure through controlled data exchange
DATA DIODES
Data Diodes and Cross Domain Solutions for Enhancing Cyber Resilience in Renewable Energy
Together, Data Diodes and Cross Domain Solutions help renewable energy operators:
- Reduce cyber attack exposure across OT environments
- Protect SCADA, control systems and critical infrastructure
- Enable secure OT-to-IT and OT-to-cloud data transfer
- Support cyber resilience and regulatory requirements
- Maintain network segmentation while improving operational visibility
- Secure connectivity across wind, solar and battery storage operations
Renewable operators increasingly depend on operational data moving between OT, IT and cloud environments to support monitoring, analytics and asset performance management. However, every new connection can introduce additional cyber risk.
Data Diodes provide hardware-enforced one-way data transfer, allowing operational data to leave critical OT environments without creating an inbound pathway that could be exploited during a cyber attack.
Where bidirectional communication is required, Cross Domain Solutions apply policy-enforced inspection, filtering and validation to ensure only authorised data can move between security domains.
TrustedFilter® enables secure OT-to-IT and OT-to-cloud data exchange through policy-enforced filtering and high-assurance Cross Domain architecture, ensuring only authorised data can move between environments while maintaining operational resilience.
Designed for critical infrastructure, TrustedFilter helps renewable operators enable secure connectivity without introducing unnecessary exposure to operational systems.
Built on over 20 years of Cross Domain expertise and supported by technologies deployed across critical infrastructure environments worldwide.
Trusted Across Critical Infrastructure and OT Environments
Supporting organisations operating distributed, high-dependency infrastructure where operational resilience and secure data transfer are essential.
OFFSHORE WIND
Securing Real-Time Operations Across Large Offshore Wind Farm
A major offshore wind operator needed a secure method of transferring operational data from a large-scale wind farm to central operations teams — without increasing cyber risk to critical infrastructure.
4Secure delivered a solution to securely export operational monitoring data from the OT environment, enabling real-time visibility for operators while maintaining complete isolation of the wind farm’s physical systems from external networks.
The relationship has since expanded to a secure OT-to-Cloud architecture across three power generation facilities, providing a fully managed, end-to-end platform for digital transformation initiatives while preserving OT security throughout.
Reduce cyber exposure from suppliers and remote access
Third-party maintainers, remote operations and vendor connectivity are essential across renewable environments, but they can also expand operational attack surfaces.
4Secure helps operators enforce controlled data exchange paths without relying on broad inbound access into operational systems.
