Microsoft Security Copilot: capacity in SCUs, roles, plugins, promptbooks, standalone vs embedded experiences and agents

Microsoft Security Copilot is a generative AI assistant for security and IT teams. It lets analysts ask questions in natural language, such as 'summarize this incident', 'explain what this PowerShell script does' or 'write a KQL query for sign-ins from new countries', and answers using a large language model grounded in data from Microsoft security products and other connected sources. It respects the user's own access: it can only retrieve data the user is permitted to see in the underlying products.
