Case Study: Rakuten Securities achieves My Number data protection for two million accounts and rapid service launch with Oracle

Rakuten Securities Strengthens My Number Data Security with Oracle

Rakuten Securities, Japan’s largest online brokerage with over two million customer accounts, needed to comply with the government’s My Number regulations and strengthen protection of sensitive personal data. The company faced a tight six-month deadline to deliver a defense‑in‑depth security platform that would centralize access control, segregate privileged duties, and enable regular log capture and early detection of illegal access across database and OS files.

Using Oracle Database Appliance X5-2 plus Oracle Advanced Security, Database Vault, and Audit Vault and Database Firewall, with Oracle Consulting support, Rakuten implemented transparent encryption, privileged‑user separation, and comprehensive monitoring without changing applications. The project launched on schedule, blocked unauthorized privileged access, improved mobile My Number registration, shortened development lead time, and delivered a compliant, high‑security platform that strengthened customer data protection and competitive position.
