How do I choose an agent governance approach?

Start from the action, not the vendor. List the irreversible actions your agents can take, then evaluate any approach on whether it can gate that specific action in the component that holds the credential, and prove it did.

Building gives control and costs engineering time on policy engines, receipt stores and approval surfaces - which must then be operated and defended at audit. Buying shortens time-to-evidence. The honest comparison is total cost of evidence, not licence price.

What must any solution do, minimum?

Attribute every consequential action to an identity, evaluate it against policy before it happens, require payload-bound approval where it is irreversible, and emit a tamper-evident receipt. Anything missing one of these leaves a gap an auditor will find.

What questions expose a weak solution?

Ask where enforcement runs - if it is in the agent's instructions rather than the effect path, it can be bypassed. Ask for a recorded refusal. Ask to alter a receipt and re-verify. Weak solutions fail one of these.

How does open evidence change the decision?

An open evidence schema means the proof can be verified independently of the vendor. Trust that cannot be verified independently is branding; portability of evidence is a real selection criterion.

What is the fastest path to a defensible state?

Govern one irreversible action class end to end, produce receipts, and show a regulator or board the evidence. It proves the model and buys time to extend coverage deliberately.

How to choose an agent governance approach

The right way to evaluate agent governance is from the action, not the vendor: list what your agents can cause that cannot be undone, then test any approach on whether it gates that action where the credential lives and proves it did.

Four tests any approach must pass

Attribution. Every consequential action ties to a distinct agent identity with an accountable owner. Shared service accounts fail this.
Evaluation. A deny-by-default policy check runs before the action, in the component holding the credential - not as advice inside the agent's prompt.
Approval. Where the action is irreversible, a payload-bound, single-use, expiring approval is required, so approving one action never silently approves the next.
Evidence. A signed, hash-chained receipt is emitted; altering it breaks verification visibly. Recorded refusals prove the gate fires.

Build, buy, and the cost that actually matters

Open-source components can lower licence cost but still require building, operating and defending the policy engine, receipt store and approval surface. The comparison that matters is total cost of evidence: what it takes to stand in front of an auditor and prove a control fired. For most teams the integration and operating layers dominate, which is why a narrow, deep first deployment beats a broad, shallow one.

The questions that expose a weak control

Where does enforcement run - the effect path, or the agent's instructions? Show me a recorded refusal. Let me try to alter a receipt and re-verify it. Can the evidence be checked without your platform? A strong approach answers all four without flinching; a weak one fails at least one. The audit checklist turns these into a scored walk, and the Gap Brief is the low-friction first read.
