CASE STUDY
Great Lakes Credit Union (GLCU), located in Bannockburn, Illinois, manages $1.4 billion in assets, serves 111,090 members, and employs approximately 231 people. The credit union faced challenges with disjointed security and risk systems, limited capacity within a small security team, and manual, labor-intensive processes. These issues made it difficult to correlate data for actionable insights and expand cyber event monitoring, leading to inefficiencies in operations and delayed responses to potential threats.
