Enterprise AI architecture is changing.
Why control is becoming a technology layer
This analysis forms part of the same operational picture as From Permission to Proof: Verifying Human Approval of AI-Agent Actions and Why Independent AI Assurance Could Become a Procurement Requirement.
The first phase focused on models.
The second focused on applications.
The next layer increasingly focuses on control.
Salesforce's Trusted Enterprise AI Harness is one indication of that shift. Its architecture includes an AI Control Plane intended to help organisations manage AI operating across an increasingly open and composable environment.
The strategic implication is larger than any individual product.
The enterprise-wide visibility requirement
As businesses deploy agents from different providers, a fragmented governance model becomes difficult to sustain.
Organisations need to know:
which agents exist → which models they use → which systems they can access → which policies apply → what they are doing → whether intervention is required.
That is creating a new enterprise category around AI control infrastructure.
For independent assurance providers, this is both validation and a warning.
Control planes and independent assurance
Simply offering “one dashboard for your AI” will become increasingly difficult to differentiate as major technology platforms add native governance.
The stronger proposition lies above individual vendors: independent evidence that controls operated correctly regardless of which model or agent provider was used.
The enterprise AI stack is therefore likely to develop multiple layers:
model → agent/application → control plane → independent assurance.
The winners may not be the organisations that attempt to own every layer.
They may be those that make the layers interoperable, visible and provable.
SOS perspective
This issue sits within our work on AI governance and assurance: practical systems should preserve evidence, human accountability and proportionate control while delivering useful automation.
