A leading U.S. competitive energy provider, the company incorporates 6 power and gas utilities, power generation, transmission, and delivery, and competitive energy sales, and serves over 10 million end customers in the United States and Canada. To improve the security posture of its NERC CIP-compliant consolidated utility interfaces, the company aimed to implement a number of new security tools and techniques, including data diodes. This project involved the unidirectional and bidirectional transfer of ICCP, SFTP, HTTPS, and PI System historian data between Production and 4 Test high availability (HA) clusters on two geographically separated instances to a power system balancing authority and neighboring utilities. After a review of proposals, the company chose Owl Cyber Defense data diodes for their capabilities in handling multiple data types and data flows, and both unidirectional and bidirectional transfers, with fewer devices, a lower overall cost, and a simpler architecture.
