The Stanford HAI Institute released the 2026 Agent Safety Evaluation Report, placing its testing focus on multi-agent collaboration. The report notes that when multiple agents exchange instructions, security risks such as permission overreach, task escape, and knowledge base tampering can easily occur. It recommends that enterprise-grade agent products must complete three layers of protection: role-based permission isolation, task audit logs, and instruction validation.

s enterprises move from single-point conversational assistants powered by large language models to deploying multi-agent teams, the security boundary becomes more complex. When multiple agents each take
