Prompt Injection Is Just the Start of AI Agent Security (Here's What You Need)

• AI agent security, particularly against prompt injection (where agents follow unintended instructions from external data), is a critical and escalating challenge as organizations scale from individual agents to hundreds.
• Microsoft’s “Agent 365” and “Project Perception” are introduced as enterprise solutions, providing agents with identities, scoping access to tasks, and featuring “Agent insights” for control gaps, “Guardian agents” for group risk management, “Dynamic permissions” for time-bound access, and “Risk-based access controls.”
• While individuals can implement basic security for personal agents (e.g., built-in checks and limited access), enterprises require sophisticated platforms to manage agent identities, dynamically control permissions, and continuously assess risk across a multitude of agents.
