I’m a storyteller by trade and recently ran a case where we split duties between autonomous agents: an intake agent, a review agent, and an approver agent. The idea was to mimic human separation of duties so no single agent could both create and approve a sensitive change.
In practice we had to lock agents to narrow scopes, require evidence passes between agents, and record each agent’s decision in an audit trail. The independent approval agent also had an independent verification step that re-ran key checks.
Has anyone configured agent teams to model governance and approvals for SOC 2? how did you prevent implicit collusion between agents and ensure independent oversight?
We assign each agent a clear, immutable role and force handoffs via signed evidence artifacts. The approver agent only sees hashed inputs and independent test results, not any raw secret. Approval emits a signed audit record that includes the test run id.
That pattern models separation of duties and gives auditors a clear chain.
We enforced narrow permissions and made agents write to a central evidence store. The approval agent only reads from that store and cannot modify evidence. That physical separation reduced risk and made audits simpler.
Adding randomness to review sampling helped. The review agent would re-run checks on a random subset of changes. If the sampled re-checks failed, we paused the entire pipeline and escalated to a human reviewer.
I set up agent teams where each agent had a cryptographic key used to sign its outputs. The approval agent only accepted inputs that carried valid signatures from the expected upstream agents. This prevented an agent from impersonating another agent. Additionally, the approver agent didn’t get raw secrets; it only received hashed summaries and test outputs. That prevented a single agent from holding all the pieces needed to both create and approve a sensitive change. We also enforced an audit policy: every handoff produced an immutable record with the agent id, timestamp, evidence location, and signature. For governance, we included a human-in-the-loop step for any high-risk action and required two independent approver agents for critical changes. These patterns mapped well to SOC 2 separation of duties requirements.
Design agent roles with least privilege, require cryptographic signatures on handoffs, and treat evidence artifacts as immutable. Limit the approver’s visibility to only what is necessary for approval and implement random re-checks to detect collusion. For high-risk items, require dual approvals or human override.
