PRONI Inc., operator of a B2B matching platform, has implemented the cloud service "SecureNavi" from SecureNavi, Inc. to obtain ISMS certification as it ramps up its IPO preparations. The initiative aims to meet client security requirements and establish the IT governance framework needed for the listing review. By shifting away from reliance on external consultants, PRONI has built a sustainable, internally-led security system. This move has resulted in more efficient IPO preparations, clearer audit requirements, and automated administrative tasks.

As it began seriously preparing for an Initial Public Offering (IPO), PRONI Inc. considered obtaining Information Security Management System (ISMS) certification. Initially relying on external consultants, the company later decided to implement SecureNavi to establish a more efficient, internally-led system and create a sustainable governance model for the organization.
**■ Background for ISMS Certification**
According to Mr. Nishimura, Group Leader of PRONI Inc.'s Information Systems Group, there were two main reasons for pursuing certification.
First was to meet customer demands. As a business matching service that handles a large volume of sensitive client information, PRONI saw a sharp increase in security questionnaire requests from business partners as its operations expanded. These questionnaires almost invariably included a question about third-party certifications, and responding individually without certification was a time-consuming process.
Second was to prepare the internal structure for its public listing. In the IPO preparation phase, it became necessary to objectively prove the security of its systems from an IT General Controls and governance perspective. The company concluded that aligning its framework with the international ISMS standard would build a solid foundation for future audits.
**■ The Deciding Factor for Choosing SecureNavi**
Looking toward future organizational growth, PRONI urgently wanted to build a sustainable system that it could manage internally, rather than depending on external parties. The company was particularly concerned about data and file dispersion and complexity, and it sought a tool that would allow it to visualize and control schedules and tasks internally.
SecureNavi's ability to centralize data and files within the tool became the key deciding factor. This feature was highly valued because it would facilitate smooth handovers even if the person in charge changed, enabling a system that the company could easily and continuously manage itself.
**■ Effects of Implementation**
The adoption of SecureNavi brought about several benefits.
1. Streamlined IT General Controls and IPO Preparations:
IPO preparations involve scrutiny of areas like account management flows and risk analysis, many of which overlap with ISMS requirements. By building its ISMS with SecureNavi, the company was able to address related tasks collectively, making the preparation process more efficient.
2. Clarification of Necessary Actions:
Determining the appropriate standards required for an audit is difficult for a company to do on its own. SecureNavi clearly defined the scope of actions required by ISMS standards, allowing the company to proceed with preparations confidently.
3. Effective Management:
Previously, information updates required manual work across multiple tools like Excel and Word. With SecureNavi, this process is centralized. When asset information is updated, it is automatically reflected in related documents, a major advantage that ensures the latest information is always consolidated and significantly improves management efficiency.
