TL;DR: Agentic AI breaks a core security assumption: systems can now chain tools, retry paths, and pursue goals at machine speed, making human intent and traditional functional fixedness unreliable, according to ColorTokens. The decisive variable is privilege, because identity, permissions, and reachability must constrain what agents can do when controls are bypassed creatively.
Editorial analysis by NHI Mgmt Group, based on content published by ColorTokens: “The Mythos Moment: When Hacking Tools Move from “Functional Fixedness” to “Divergent Hacker Thinking””.
Key questions
Q: What breaks in zero trust when agentic AI can choose alternate tool paths?
A: Zero trust breaks when it assumes the actor will follow a predictable workflow after authentication.
Q: Why do autonomous agents make privilege more important than intent?
A: Autonomous agents can operate without human moral pressure, social consequences, or review delays.
Q: How can security teams tell whether zero trust is actually containing agent behaviour?
A: The best signal is whether an authenticated agent remains trapped inside its intended task scope.
Practitioner guidance
- Define agent-specific privilege boundaries Map each agent to the narrowest set of tools, APIs, and data paths it needs, and remove broad reusable permissions that assume predictable behaviour.
- Segment agent reachability by task Use microsegmentation to prevent an authenticated agent from moving beyond the intended application, environment, or workload boundary.
- Review human trust assumptions in access models Identify places where current policy relies on human judgment, reputation, or organisational role as a proxy for safe action, then replace that assumption with explicit enforcement.
Bottom line: Agentic AI weakens zero trust assumptions because the actor can adapt its path after access is granted, making intent less reliable as a control boundary.

Agentic AI creates an assumption collapse, not just a new control gap: zero trust and traditional access models assume the actor's intent is knowable enough to govern at provisioning time. That assumption fails when the actor can decide, chain tools, and pivot at runtime without human approval. The implication is that identity governance must stop treating intent as the stable control variable.
A few things that frame the scale:
- 90% of IT leaders say properly managing NHIs is essential for a successful zero-trust implementation, according to the Ultimate Guide to NHIs.
A question worth separating out:
Q: Should organisations treat microsegmentation as part of identity governance for AI agents?
A: Yes. For agentic systems, segmentation is not just a network design choice. It is an identity control that limits blast radius by constraining where an agent can go after access is granted, which is exactly where creative misuse becomes costly.
