Current State in 2025: Rising Risk of Data Breaches via Business Partners

In recent years, cyberattacks targeting supply chains have become increasingly severe. According to one survey, approximately 60% of companies with over 1,000 employees reported experiencing or suspecting data breaches originating from their business partners. This indicates that even robust internal security measures are no longer sufficient to ensure safety. Vulnerable vendors and subcontractors are now common targets. In this context, regulatory guidelines from Japan’s Financial Services Agency and Ministry of Economy, Trade and Industry emphasize the importance of risk assessments that include third parties. Strengthening security among business partners has thus become an urgent priority and a key strategic concern for enterprises.

Annual Vendor Assessments Lead to Over-Reliance on Individuals and Excessive Workload

Many companies currently conduct vendor evaluations using checklists. However, creating, updating, collecting, and verifying these checklists requires significant time and effort. It is not uncommon for a limited number of staff to handle hundreds of assessments annually. As a result, the evaluation process becomes dependent on specific individuals, leading to inconsistent judgment criteria and difficulties in verifying the accuracy of responses—ultimately reducing assessment quality. This strains core business resources and increases the risk of delayed responses or overlooked vulnerabilities. These challenges are widespread across organizations, highlighting the limitations of traditional methods in terms of scalability and sustainability.

A New Method: Leveraging Third-Party Assessments to Streamline Checklist Management

This seminar introduces a new approach to reduce the burden of traditional checklist-based evaluations by utilizing Assurance Inc.'s "Corporate Evaluation Service." Certified cybersecurity experts conduct assessments on behalf of clients, adhering to international standards such as ISO and NIST, ensuring comprehensiveness and objectivity. Furthermore, evaluation results are centrally managed on a digital platform, enabling prevention of false reporting and rapid responses to emerging risks. This approach significantly reduces the manpower required for vendor assessments while simultaneously enhancing the overall security posture of the supply chain. Practical case studies will be presented to illustrate how this method effectively combines efficiency with improved reliability.
