Four unrelated vendors shipped agent authorization control planes inside 48 hours.

Between September 2 and 3, the same product shape appeared in four categories. Genesys announced an AI Control Plane deciding who gets access to which AI tools, what they can do, how tools are discovered and how to shut them off. JetStream announced Clearance, a zero-trust reasoning engine authorizing every agent tool call at its AI Gateway before execution, launched on a $34M seed. AccuKnox released AgentZ bundling sandboxes, RBAC, runtime credential injection and audit traces with SaaS, on-prem and air-gapped deployment. And a solo builder posted Oconee Runtime to Show HN as policy enforcement for browser AI and coding agents. All four describe one primitive: a per-action allow/deny decision made before the tool call rather than an audit log read after. When a category forms at enterprise, security, platform and indie scale simultaneously, it usually becomes table stakes rather than a product.
