Microsoft Copilot security guide and productivity tips for Japan

As Japanese firms adopt generative AI tools such as Microsoft 365 Copilot, they face new security risks including data overexposure, compliance breaches, and unintended sharing of confidential information with unauthorized "shadow AI" services. Microsoft recommends using the Purview platform to automatically apply sensitivity labels to files, enforce Endpoint DLP to block uploads to external AI sites, detect insider threats like departing employees extracting data, and leverage Data Security Posture Management to visualise vulnerable configurations.

For users seeking to maximise Copilot’s efficiency, Microsoft has added shortcuts (Win + C, Alt + Space, “Hey Copilot”), privacy controls to opt out of AI model training, and a connector that links Copilot to Google services such as Calendar, Gmail and Drive. New features such as Copilot Vision enable AI‑driven image and video analysis, while built‑in image‑editing, cheat‑sheet generation, and prompt‑template guidance help streamline daily tasks. Experimental tools in the "Experiments" lab let users trial upcoming capabilities, and history import/export functions support migration from other AI platforms.
