TL;DR: Agentic AI systems build trust through transparency, human oversight, technical guardrails, security controls, and continuous improvement, according to Twine Security’s guide on building confidence in autonomous software. The hard question is not whether agents can be trusted, but which identity controls still assume a human-paced approval model and therefore fail when decisions happen at runtime.

Editorial analysis by NHI Mgmt Group, based on content published by Twine Security: “Building Trust in Agentic AI”.

Key questions

Q: What breaks when AI agents inherit human IAM controls?

A: Human IAM controls break because they assume a person makes a request, waits, and can later be reviewed or deprovisioned.

Q: Why do autonomous AI agents increase insider risk even when access is technically authorized?

A: Autonomous agents increase insider risk because authorization alone does not explain purpose.

Q: How do security teams know if AI governance is working?

A: Look for evidence that access decisions are reviewable, permissions are revocable, and exceptions are not becoming permanent.

Practitioner guidance

  • Define agent-specific approval thresholds Classify which identity actions require human sign-off, which can be delegated, and which must remain blocked for AI agents handling IAM tasks.
  • Instrument reasoning and action logs Capture the context, chosen action, and outcome for each agent-driven identity decision so auditors can reconstruct why access changed.
  • Bound autonomous access to task scope Restrict AI agents to the narrowest identity workflow they need, and prevent tool or privilege expansion outside that scope.

Bottom line: Agentic AI changes the trust model because access decisions can now be made and executed by the same actor inside the same runtime session.

Human-paced approval is a broken assumption for agentic IAM: Access review, sign-off, and recertification were designed for identities that hold privileges long enough to be observed and certified. That assumption fails when an agent can acquire and use access inside a short runtime window, then move on before review begins. The implication is not just more automation, but a different governance model for decision-time authority.

A few things that frame the scale:

  • 53% of security leaders expect AI to run major portions of their infrastructure autonomously within the next three years, according to the 2026 Infrastructure Identity Survey.

A question worth separating out:

Q: Should organisations treat AI coding agents as part of IAM and PAM governance?

A: Yes, when those agents can act on code, data, or tools in ways that affect production risk. Their permissions should be scoped, reviewed, and audited like other privileged systems, especially when they interact with sensitive routes, secrets, or regulated data. The governance question is who can let the agent act, and under what policy.
