Mitsubishi Tanabe Pharma streamlines cloud security operations and employee literacy

Use case typeRisk assessmentUpdated Jun 13, 2026

Mitsubishi Tanabe Pharma, a leader in the pharmaceutical industry, sought to improve its cloud security operations amid a company-wide push for digital transformation and data utilization. The company was challenged by the increasing complexity of cloud security, especially as workflows expanded into precision medicine and patient-centric solutions. Security incident checks and alerts primarily in English made rapid response and understanding difficult for its Japanese-speaking team. To address these issues, the firm undertook a comprehensive assessment of its Azure-based infrastructure with Microsoft guidance, adopting Microsoft Defender for Cloud and Microsoft Sentinel for consistent policy enforcement and continuous monitoring. The real breakthrough came with the integration of Azure OpenAI Service, which automated the translation and summarization of security alerts into Japanese and provided clear explanations of threats and recommended actions. This reduced incident handling time tenfold and significantly bolstered employee security literacy. Now, security incidents are handled more efficiently by a lean team, supporting the company's 'VISION 30' strategy for advanced, secure digital healthcare initiatives.

Architecture

The solution architecture includes Microsoft Defender for Cloud as a central platform for managing security policies and workloads, integrated with Microsoft Sentinel for SIEM functions—collecting and analyzing security logs, managing identity-based access, and issuing automatic alerts. Azure OpenAI Service is used to process incident messages: translating, summarizing, and annotating security alerts into Japanese, then distributing them via email and Microsoft Teams. The automation leverages Azure Logic Apps for workflow orchestration, connecting Defender for Cloud and Sentinel incident data to OpenAI and onward notification channels.
