Video

Scaling Insider Threat Detection and SOC Efficiency at Financial Scale

See how Mizuho Financial Group transformed its security operations with Exabeam User and Entity Behavior Analytics (UEBA)—enabling real-time anomalous behavior detection across massive log volumes while reducing analyst workload.

In this customer story video, key cybersecurity leaders from Mizuho Financial Group, Mizuho Bank, and Mizuho Securities share how adopting Exabeam transformed their approach to insider risk management and security monitoring:

• Proactive Insider Risk Prevention: How AI-driven behavioral analytics (UEBA) pinpoints anomalous activity and potential data exfiltration before damage occurs.
• Overcoming Log Silos: Moving away from manually checking logs across isolated security systems to automated, real-time log ingestion and analysis.
• Chronological User Timelines: How Exabeam automatically aggregates logs across diverse security controls and presents them in timeline views by user and device.
• Beyond Rule-Based Monitoring: Detecting unknown, unforeseen risks that traditional static rules miss, ensuring comprehensive coverage as business environments evolve.
• Effortless Third-Party & Cloud Integration: Seamlessly integrating with existing security infrastructure, cloud environments, and SOC services without slowing down business operations.
• Elevating SOC Productivity: Reducing manual monitoring fatigue so security analysts can focus on high-impact strategic tasks.

About Mizuho Financial Group’s Transformation

With the expansion of remote work, new communication platforms, and digital transformation across the financial sector, monitoring volume and complexity grew exponentially for Mizuho Financial Group. Traditional rule-based monitoring required manual log inspection across multiple systems, creating visibility gaps and delaying incident response.

To address these challenges, Mizuho deployed Exabeam in 2023 across Mizuho Financial Group, Mizuho Bank, Mizuho Trust & Banking, and Mizuho Securities. By establishing normal behavioral baselines for every user and asset, Exabeam empowers Mizuho’s security team to automatically detect subtle deviations and prioritize high-risk insider threats in real time.
