SENT1NEL-
GoVERNANCE LAYER FOR AI

SENT1NEL from UN1TY

​

The problem        

AI is moving into operational decision-making. As regulated and professional businesses adopt these tools, they need clear governance, control, evidence and human accountability around the decisions AI helps to support.

​

Policies and acceptable-use rules help set expectations, but they do not supervise each decision as it happens.

​

A workflow may still approve, recommend or route a case in a way that conflicts with risk appetite, approval requirements or available evidence. This could be disastrous for a business.

​

What Sent1nel is

SENT1NEL is a standalone governance layer for AI-enabled workflows. It receives decision events, evaluates them against business policy, and records a defensible evidence trail.

It is workflow-solution agnostic.

​

SENT1NEL is designed to work alongside the tools businesses already use, from Microsoft Copilot and workflow automation platforms through to Salesforce, AWS, bespoke applications, AI agents and case-management systems.

​

Control outcomes  

Record where monitoring is enough. Allow where controls are met. Escalate where human judgement or further evidence is needed. Block where the rules identify a non-overridable breach.

​

This gives firms a proportionate model: passive visibility for lower-risk activity and active intervention where the decision carries higher risk.

​

How it works    
1.    The workflow sends the AI decision to SENT1NEL
SENT1NEL receives the AI recommendation, supporting facts and evidence.

2.    SENT1NEL checks the controls
It looks for policy breaches, missing evidence, low confidence, high-risk indicators and required approvals.

3.    SENT1NEL decides what happens next
It can record, allow, escalate or block the decision.

4.    A human reviews exceptions
Where controls are not met, SENT1NEL routes the case for human review and captures the outcome.
 

Use Cases  

AI can assist with analysis, summarisation and recommendation, but higher-risk processes still require accountable judgement.

​

SENT1NEL makes that control point explicit: the AI assists, the rules check, the evidence is captured, and the human remains accountable where the risk profile requires it.
