Essential AI Security Seminar for Business Leaders

On October 28, 2026, at 16:00, a crucial seminar titled "How Secure Is Your Company's Generative AI? Immediate Security Inspection Session" will be held in Shinjuku by Keiei Sanbo Co., Ltd. This event is exclusively designed for business leaders and aims to address vital questions about the security measures related to generative AI deployment in organizations. The distinguished speaker for the event is Fuyuki Matsubara, CEO of Arrowheads Inc., which is notable for achieving a perfect score at the 2026 Ministry of Defense Cyber Contest.

Context of the Event

The primary concern posed by the seminar focuses on whether leaders can confidently assert that the generative AI utilized in their companies is secure. Many executives may find it difficult to respond affirmatively, as they must contend with various issues. For instance, are employees inadvertently entering confidential materials into external accounts? Is the information submitted still subject to AI learning? Leaders must also consider if they are aware of AI tools, often referred to as Shadow AI, that employees may be using without official oversight. Moreover, do they fully understand the permissions granted to AI agents and external tools?

The seminar aims to illuminate the fundamental security aspects of generative AI, stressing that much of the risk could be mitigated through effective inventory management and awareness. Unfortunately, many executives lack guidance on what to check or address in securing generative AI. This event is not meant to induce fear but to empower executives to closely assess their company's situation and to take immediate corrective actions.

• - Latest Cases of Data Breaches: Examine real-life incidents involving generative AI companies.
• - Risks of Free Versions and Personal Accounts: Identify settings that can be revised today.
