Why it matters
Microsoft's shared responsibility guidance helps defenders reason about who must configure, operate, and monitor controls for autonomous agents that can invoke tools and cross session or user trust boundaries.
Microsoft's Azure documentation lays out an 'AI agent shared responsibility model,' explaining how autonomous agents differ from request/response LLMs by acting through tools, holding persistent memory, carrying their own identity, and composing with other agents. The guidance names top agentic risks including prompt injection that drives actions, excessive agency, and confused-deputy scenarios, and maps governance responsibilities across SaaS and other deployment models.
