Why Least Privilege Is Critical For AI Security
Varonis, Thursday, July 24th, 2025
From writing emails to analyzing financials and coding, AI has quickly become integral to the way we work. At the same time, AI tools and agents reveal the cracks in an organization's data security. In these AI-enabled organizations, enforcing the principle of least privilege (PoLP) is more important than ever.
AI shines a spotlight on excessive access that might have otherwise gone unnoticed. AI tools and agents, like ChatGPT Enterprise, Microsoft 365 Copilot, and Salesforce Agentforce, operate from the same permissions as the user invoking them. When over-permissioned or compromised users have access to AI tools and agents, the risk of exposure and data breach increases exponentially. With 88% of organizations harboring ghost users and tens of thousands of stale permissions as well, the risk surface is already out of control.
In this blog, we'll explore why enforcing least privilege is essential in the age of AI, how over-permissioned data creates risk, and how Varonis helps organizations stay secure while embracing AI innovation.
