UAE Based Oil & Gas Refinery
Defending a refinery's legacy OT systems


Customer:
A Leading Oil & Gas refinery in Dubai, United Arab Emirates

Challenge:
The refinery needed to maintain secure access to plant data while facing increased cyber threats on their ICS
Their legacy Wonderware Historian (AVEVA System Platform) was out-of-support, requiring a Unidirectional Gateway solution that integrated seamlessly without modifications.

Waterfall’s Unidirectional Security Gateway Solution:
Offered native integration with Wonderware AVEVA System Platform.
Waterfall’s R&D team customized the integration connector to work flawlessly with the out-of-support legacy system, avoiding any modifications.
Provided a continuously updated replica of the Historian server on the commercial IT network, ensuring the actual production server remained isolated and data flowed one-way (From OT to IT).

Results & benefits
100% Secure OT Network: Unbreachable by remote cyber threats.
Real-time Data Visibility: Full and secure access to real-time production data.
Legacy System Unaltered: No modifications required to the customer’s legacy systems.
Scalability: The refinery’s success led to them ordering additional Waterfall Unidirectional Security Gateways for further applications.
