Case Study: BBCN Bank achieves detection of lateral movement and reduced false positives with Exabeam

BBCN Bank Detecting Lateral Movement and Service Account Activity

BBCN Bank, a Los Angeles–headquartered community bank with more than $7.8 billion in assets and 59 branches, faced growing credential-based threats—particularly malicious lateral movement using service accounts and account switching. Although the bank had a market-leading SIEM, it required heavy manual rule creation and struggled to detect complex credential attacks, a challenge for BBCN’s small security team.

BBCN piloted and deployed Exabeam to provide user and entity behavior analytics that augments the SIEM. Exabeam’s agentless, low‑overhead platform and Stateful User Tracking™ improved visibility into lateral movement and service-account activity, enabled customizable risk scoring, and delivered measurable benefits: fewer false positives, better insight into user/system activity, and reduced workload for security personnel.
