An iPaaS such as Boomi or MuleSoft moves data reliably but does not enforce agent-level policy, authentication, and action logging on its own. A governance control plane is designed to sit above the iPaaS, loosely coupled and platform-agnostic, and intercept agent actions before they reach enterprise systems. For read-only, single-system agents, native platform controls may be enough. For agents that act across systems or carry financial and regulatory consequence, the control plane adds the zero-trust authentication, dynamic policy gates, and kill switch that an integration platform was not built to provide.
