About The Customer
Insight Credit Union is a state-chartered credit union that was founded in 1935. It is dedicated to improving the financial lives of those who live and work in the communities it serves. Insight serves 55,000 members in Orange, Seminole, Volusia, Osceola, Lake, Sumter, Citrus, and Marion Counties. As a full-service financial institution with more than $550 million in total assets, Insight offers banking, loans, mortgages, and investments to anyone who lives or works in Central Florida.
The Challenge
Insight Credit Union was faced with the challenge of securing various types of confidential data stored on their file servers. The credit union needed a solution that could detect anomalous activity that could potentially lead to a security breach. Additionally, they needed a system that could accelerate the investigation and remediation of incidents and operational issues. The challenge was to find a solution that could provide real-time alerts on suspicious activities, identify high-risk accounts, and mitigate potential ransomware attacks.
The Solution
Insight Credit Union implemented the Netwrix Auditor, a solution that had been previously used and appreciated by one of their employees, Alex. The Netwrix Auditor provided visibility into anomalous behavior, sending alerts on activities that could be a sign of a security incident. These activities included logons outside business hours, multiple failed logons, changes to permissions, and non-owner mailbox access events. Alex was able to review users’ risk scores on a daily basis to identify high-risk accounts, enabling him to take action before a security breach occurred. The solution also helped in the mitigation of ransomware attacks by alerting on mass data removal or modification and excessive failed access attempts. Furthermore, the Netwrix Auditor optimized investigations with its Interactive Search feature, which was used to investigate operational issues such as lost files or a user’s inability to log in to certain applications.
Operational Impact
  • The implementation of the Netwrix Auditor has significantly improved the security posture of Insight Credit Union. The solution has provided visibility into anomalous behavior, enabling the credit union to detect potential security incidents in their early stages. The alerts on mass data removal or modification and excessive failed access attempts have been instrumental in mitigating ransomware attacks. Additionally, the solution has optimized investigations, making it easier to investigate operational issues such as lost files or a user’s inability to log in to certain applications. The state-in-time reports have also been beneficial, enabling the comparison of current and past system configurations.
Quantitative Benefit
  • Fast detection of abnormal activity and ransomware within a couple of minutes
  • Prompt investigation and remediation of issues
  • Daily review of users’ risk scores to identify high-risk accounts
