Protecting Business Partners: The Cutting Edge of Cyber Incident Response Seminar

On September 11, 2025, Tsuji & Hongō Tax Corporation, headquartered in Shinjuku, Tokyo, will kick off an online seminar titled "Protecting Business Partners: The Cutting Edge of Cyber Incident Response." In recent years, small and medium-sized enterprises have increasingly become targets of cyberattacks, putting not only their operations at risk but also exposing client information and leading to operational paralysis.

Even companies with solid security measures are finding it challenging to completely avoid damage. Thus, how to respond after an incident has occurred becomes crucial. This seminar aims to provide practical and straightforward guidance on initial and post-incident actions from a perspective that all business leaders, information systems personnel, and internal management staff should not miss, especially those part of the supply chain.
