TL;DR: Opal Security says AI agents need just-in-time access governance because standing grants, unclear ownership and human-paced review cycles cannot keep up with agent growth; its model ties every request to an owner, a purpose and policy at the point of access. The assumption that privilege can be reviewed after issuance breaks when access decisions happen faster than governance.
Editorial analysis by NHI Mgmt Group, based on content published by Opal Security: “Introducing Opal Zero: Q&A with CPO Sameer Mehta”.
Key questions
A: Security teams should treat agent permissions as ephemeral and context bound, not permanent entitlements.
Q: Why do autonomous agents make traditional access reviews less effective?
A: Access reviews assume permissions persist long enough to be observed, challenged, and recertified.
Q: What are the signs that agent access is becoming ungovernable?
A: Look for shared secrets across tools, inherited CI identity, inconsistent credential use between runs, and logs that cannot explain which prompt led to which action.
Practitioner guidance
- Define an owner for every AI agent Require a named business or technical owner before any agent can receive production access, and make ownership part of the access record used for review and revocation.
- Bind access to declared purpose Document what each agent is expected to do, then block requests whose requested resources exceed that purpose or whose activity indicates purpose drift.
- Move approvals to the point of access Evaluate each agent request at runtime against current context, then issue only scoped, expiring permissions instead of persistent grants.
Bottom line: AI agents change access governance from a periodic review problem into a live authorisation problem.
What's in the full announcement
Opal Security's full article covers the product mechanics this post intentionally leaves at a higher level:
- How Opal Zero evaluates each request using owner, purpose, blast radius and current context
- How Gateway Sync enforces scoped, time-bound policy in existing gateways already on the path
- How the Risk Center identifies unowned, dormant and overreaching agent access for revocation
- How the platform maps agents from identity providers and AI systems into one access graph

Just-in-time governance is now the right control model for AI agents. Standing grants were designed for access that stays stable long enough to be reviewed, certified and revoked on a human schedule. AI agents turn that assumption into a liability because their access decisions are made repeatedly and can change during execution. Practitioners should treat point-of-access policy as the governance centre of gravity, not an optimisation layer.
A few things that frame the scale:
- Only 44% of organisations have implemented any policies to manage their AI agents, despite 92% agreeing that governing AI agents is critical to enterprise security, according to the 2026 Infrastructure Identity Survey.
A question worth separating out:
Q: What is the difference between human IAM review cycles and AI agent governance?
A: Human IAM can often rely on slower certification cycles because a person's role, accountability and work patterns are comparatively stable. AI agents need continuous context-aware decisions because their access can change within a single session, so the control must move closer to the request itself.
