Least Privilege for AI Agents: A Practical Guide for Security Leaders
Varonis, Wednesday, October 7th, 2026
Varonis explains how to give each AI agent its own identity and only the time-limited, task-specific access it needs.
Varonis defines least privilege for AI agents as giving every agent its own identity, task-scoped access and permissions that expire when the task ends, plus runtime checks on high-impact actions.
Human-centric access models break down because agents inherit user permissions, run on shared service accounts and act at machine speed, and a SailPoint survey found only 44% of organizations have policies to secure agents, while OWASP names excessive permissions as a root cause of excessive agency.
Varonis argues that an agent's privilege should be measured by the sensitive data it can reach as well as the tools it can call.
