Great Lakes Credit Union Case Study

GREAT LAKES CREDIT UNION

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.

THE CHALLENGE

“The strength of DefenseStorm’s CTS Ops comanaged service and Threat Surveillance product lies in their capacity to sift through and provide actionable alerts for prompt and accurate responses. This degree of vigilance and assistance is crucial in protecting our operations.”
