Great River Energy

Great River Energy, the second largest power supplier in Minnesota, is a notfor-profit company that generates and transmits electricity to 28 distribution cooperatives in Minnesota and Wisconsin. Those member cooperatives then distribute electricity to more than 645,000 member consumers—or about 1.7 million people. With so many relying on Great River’s service, any disruption, for any reason, can affect a large area. While storms and other weather incidents can certainly be a temporary risk to service, cyberattacks—which are becoming more frequent in critical infrastructure industries—can cause longer-lasting damage. That’s why utilities like Great River Energy are proactively adopting change configuration and compliance solutions to strengthen security across IT systems.

 

It was time to upgrade and automate our systems to ensure security and compliance. Tripwire helped us meet that goal.
Joseph Vanhoorik, Security Engineer for Great River Energy
