TL;DR: Agent2Agent (A2A) standardises how autonomous agents discover one another, exchange tasks, and use short-lived OAuth/OIDC tokens, but it also introduces compliance blind spots and orchestration overhead, according to Apono. The real issue is that agent-to-agent communication makes identity, auditability, and least privilege a runtime governance problem, not just an integration problem.
Editorial analysis by NHI Mgmt Group, based on content published by Apono: “What is Agent2Agent (A2A) Protocol and How to Adopt it?”.
Key questions
Q: Where does Agent2Agent fail if teams rely only on logging and not authorisation?
A: It fails at the point of delegated execution.
Q: Why do short-lived agent tokens still create governance risk?
A: Because short-lived does not mean well-governed.
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 task-scoped authorisation for agents Bind every cross-agent request to a narrow purpose, explicit audience, and short lifetime so the token cannot outlive the task it was issued for.
- Inventory agent discovery endpoints Track every /.well-known/agent.json or registry entry as an identity asset, because discovery data now determines who can ask for work and how.
- Correlate token issuance with task execution Join issuer logs, trace IDs, and task outcomes so investigators can tell who approved access, which agent acted, and when the action completed.
Bottom line: Agent2Agent pushes identity governance into the execution path, where discovery, token issuance, and auditability must be controlled in real time.

Agent2Agent adoption turns runtime delegation into the new governance surface: The central issue is no longer whether agents can talk to each other, but whether those conversations are authorised, time-bounded, and reconstructable. A2A moves identity decisions into the middle of execution, which means governance has to keep pace with the transaction, not the deployment. Practitioners should assume the control plane is now part of the workload.
A few things that frame the scale:
- Only 13% of organisations feel extremely prepared for the reality of agentic AI despite the majority racing toward autonomous adoption, according to the 2026 Infrastructure Identity Survey.
A question worth separating out:
Q: How should security teams govern Agent2Agent communication in production?
A: Treat every agent as a governed non-human identity, not just a service integration. Require ownership, scoped authentication, traceable task IDs, and lifecycle offboarding before the first production workflow goes live. If an agent can discover peers and request access at runtime, it belongs inside identity governance and audit processes.
