NTT DOCOMO Business introduced SecureNavi's ISMS and P-mark automation tool in January 2025 at the division operating the SkyWay real-time communication platform. The company reduced external consulting costs and achieved in-house ISMS operations without increasing staff workload, according to a case study published by SecureNavi Inc.
The division obtained ISMS certification in November 2024 but found that Word and Excel documents created under external consultant leadership were scattered across shared folders, making rule connections hard to follow. Manual version control and approval workflows had become complicated, and risk assessments with complex numerical calculations did not match actual practice.
SecureNavi was chosen after comparing options on three points: cost performance, resource use without a dedicated person in charge, and centralized document management with visualized change histories and approval workflows.
After the January 2025 introduction, the division cut external consulting costs while building a self-led maintenance system. Audit response improved as evidence became centrally managed and visualized, and organizational handovers to new members took about one and a half hours of meetings.
