Case Study: Mizuho Financial Group strengthens security governance and prevents data leakage with Exabeam

Mizuho Financial Group cuts manual log review with LogRhythm and speeds incident response

Mizuho Financial Group, one of Japan's leading financial organizations, faced a significant challenge in strengthening its security governance and preventing internal data leakage. The group needed a solution to proactively detect unknown threats and signs of insider fraud across its many subsidiaries, a difficult task with its previous manual log-checking processes. To address this, Mizuho implemented the Exabeam New-Scale Analytics platform.

By deploying Exabeam, Mizuho established a system that uses machine learning to analyze employee behavior and automatically detect abnormal activities that deviate from a learned baseline. This solution from Exabeam greatly reduced the monitoring workload, improved detection accuracy, and enabled faster response times. The Exabeam dashboard also visualized risk status, allowing the company to prioritize high-risk users and systems, making incident response more efficient and comprehensive.
