How Rakuten transformed insider risk management

A large organization with 40,000 employees, Rakuten launched an insider risk management program in 2019 after a customer requirement pushed them to implement a more robust data loss prevention solution as remote work expanded.

Rather than relying on traditional prevention-based DLP controls, the company adopted a detection-focused strategy by integrating Mimecast Incydr with Exabeam Advanced Analytics to monitor file activity and flag anomalous behavior.

An initial insider risk assessment revealed significant gaps in access controls and employee lifecycle management, making clear that the initiative required building a full program and culture — not just deploying software.
