Closed-loop response is a governance configuration, not a binary feature

Control is implemented differently

Cisco describes consequential actions as human gated. Palo Alto documents RBAC, sensitive-action approval, and action logging. SentinelOne says teams choose where AI acts and where sign-off is required. Conifers describes staged progression from human-in-the-loop to human-on-the-loop. D3 emphasizes a unified audit trail and configurable autonomy.

What actually differs?

A generic human-in-the-loop label hides four implementation questions: which actions are classified as sensitive, whether classification is configurable, whether logs cover reasoning and execution, and whether a workflow can cross from recommendation to action without a new approval.

Governance test plan

Buyers should enumerate action classes, test default-deny behavior, confirm tenant and role boundaries, inspect audit records, and exercise stop and rollback paths. A product can document an approval feature while a local workflow is configured to bypass it. ASI records the documented boundary, not the buyer's deployed configuration.

Confidence

Palo Alto supplies the most specific technical-documentation statement in this comparison. The other records are primarily vendor announcements or product pages. No qualifying independent validation of closed-loop control effectiveness is present.
