Building trust in AI: Securing data, compliance and confidence

For IT leaders aiming to harness AI to meet evolving business needs, one thing is clear: success begins with trustworthy, secure and well-managed data. AI is only as effective as the information it learns from, and that trust starts long before any model is trained. 

Just as you would not build a skyscraper without a solid foundation, you should not develop AI solutions without strong data governance in place. 

The Trust Gap in AI Adoption 

According to a recent study by Gartner, the two biggest risks when deploying AI are: 

1. Exposure of sensitive data, often caused by oversharing, weak controls or inadequate privacy protections
2. Poor outcomes, such as inaccurate, biased or legally risky outputs, when AI models rely on low-quality or unmanaged data

In a 2025 Gartner survey, 71% of respondents cited security and governance as key concerns in deploying Microsoft 365 Copilot. 

Without trust, AI will never achieve its full potential, even if the technology itself is sound.  

A key message from the 2025 Gartner Data & Analytics Summit was simple:  “If you cannot trust the data, you cannot trust the AI.” 

Data governance is not a compliance checkbox. It is the foundation for transparency, confidence and responsible use. 

Why Governance Matters Now More Than Ever 

Failing to establish strong governance introduces significant risk: 

• Increased bias and error: AI models trained on poor or inconsistent data can produce flawed or unfair results. 

• Regulatory breaches: Without clear data lineage, organisations risk falling foul of regulations such as the GDPR and upcoming UK AI laws. 

• Loss of trust: If customers or colleagues feel AI decisions are unexplainable or unfair, reputational damage can follow quickly. 

How to Build Trust at Scale: Tools and Frameworks That Work 

Establishing AI trust requires more than policy. You need governance woven into your technology and workflows. Here are proven tools that can help, using Microsoft’s own ecosystem. 

Microsoft Purview 

Unified Data Governance and Compliance.

Microsoft Purview provides a centralised approach to managing data across Azure, hybrid and multi-cloud environments. 

Key features that support AI trust include: 

• Data discovery and classification 

• Automatically identify and label sensitive or regulated data 

• Data lineage tracking 

• Visualise how data flows from source to model, enhancing explainability 

• Policy enforcement 

• Set and apply access, retention and usage policies in one place 

• Track who accessed sensitive datasets and when 

Use case: Protect sensitive customer or HR data from being used by Copilot by setting sensitivity labels and access policies in Purview. 

Microsoft Entra 

Identity and Access Governance for AI Workflows.

Trust is not just about the data. It is also about who can access it and what they can do with it. 

Microsoft Entra enables you to manage identity and permissions effectively: 

• Least-privilege access 

• Only the right people and services access the right data 

• Lifecycle management 

• Automatically adjust access as users join, move or leave 

• Access reviews and audit trails 

Use case: Restrict and log who can modify or publish AI models trained on internal data. 

Microsoft 365 Compliance and Purview for Copilot 

As Copilot use grows across Microsoft 365, your governance practices must follow. 

Combine Microsoft 365 Compliance features with Purview for: 

• Information barriers 

• Prevent data from crossing between departments where it should not 

• Data Loss Prevention (DLP) 

• Stop Copilot from referencing confidential terms in content 

• Audit and eDiscovery 

• Monitor how AI-generated content is created and used 

Use case: Prevent Copilot in Outlook from using client-specific financial information without permission by applying DLP and sensitivity labels. 

Final Thought: Governance Is the Foundation of Trusted AI 

AI is reshaping how businesses operate and make decisions, but only if people trust the technology behind it. Data governance is not optional. It is the foundation that allows you to innovate confidently and ethically. 

Start today. Build the trust you need through data governance, or risk watching both your models and your reputation falter.
