Why Access Controls Fail for AI Agents: The Intent Validation Gap
By
Alex Vakulov
The kind of bagel that ruins lesser bagels for you.
Summary
The article argues that traditional access controls are insufficient for AI agents because they validate identity and permissions but cannot validate intent or determine whether an action is sensible. As AI agents increasingly operate autonomously within enterprise environments—calling tools, triggering workflows, and making decisions—this gap creates a critical security vulnerability. The author contends that current security stacks were not designed for AI agents, and the rapid transition from experimental to production-ready AI tools has outpaced security measures. The piece calls for new security paradigms that can assess the context and reasonableness of actions, not just who or what initiated them.
Key quotes
· 5 pulledAccess controls can confirm who or what is allowed to act. They cannot always tell whether the action makes sense.
That gap becomes dangerous with AI agents, which can call tools, trigger workflows, and make decisions.
The problem is that agents may do all this before anyone gets the chance to read the output or decide whether it was a good idea.
There is a real vulnerability in the fact that the industry did not design its security stacks to deal with AI agents.
AI agents quickly went from an interesting experiment to tools already running inside your environment.
