Deploying Copilot Studios Safely with Microsoft Purview

As we’re working with more Am Law firms than ever on Microsoft Copilot Studio implementations, we’re noticing a consistent trend – teams are building impressive AI capabilities, but governance often comes as an afterthought. 

If your firm is already experimenting with custom copilots, or planning to, this presents both an opportunity and a challenge. The technology is powerful and relatively easy to deploy, but without proper Microsoft Purview controls, those copilots can access far more sensitive data than intended. 

 

Understanding the Scope of Access 

Copilot agents integrate deeply with your Microsoft 365 environment. They can pull information from Outlook, Teams, OneDrive, SharePoint, and other connected systems. This broad access is what makes them useful, but it also creates potential exposure. 

Without appropriate governance controls, a copilot designed for one purpose might inadvertently surface: 

  • Client matter details from unrelated cases 
  • Internal compensation or HR information 
  • Draft documents and work product 
  • Confidential firm strategy or financial data 
  • Privileged communications 

For law firms, this represents both a security concern and a potential compliance issue, particularly around client confidentiality obligations. 

 

The Governance Gap 

Microsoft Copilot Studio makes it straightforward to build AI assistants, which is excellent for productivity. However, the platform assumes you have robust data governance already in place. Many firms don’t. 

Microsoft Purview provides the necessary governance framework through: 

  • Sensitivity labels for data classification 
  • Access controls and permissions management 
  • Data loss prevention policies 
  • Audit trails and compliance reporting 
  • Retention and disposition controls 

The challenge is that Purview requires thoughtful configuration for legal environments. Generic corporate policies often don’t account for the unique data sensitivity requirements of legal practice. 

 

Our Approach to Governed Copilot Deployments 

We’ve developed a structured approach to help law firms deploy Copilot Studio safely and effectively. Our 60-hour engagement focuses on getting both the technology and governance right from the start. 

Discovery & Planning: We work with your team to understand specific use cases, identify data sensitivity requirements, and map out appropriate governance policies. 

Design & Configuration: We configure Copilot Studio alongside Microsoft Purview, setting up sensitivity labels, access controls, and policies that protect sensitive information while supporting legal workflows. 

Implementation: We deploy the configured solution in a controlled manner, test thoroughly, and ensure everything works as intended. 

Training & Handover: We provide documentation and training so your team can maintain and expand the system over time. 

Our focus is on creating governance frameworks that protect sensitive data without creating friction in day-to-day legal work. 

 

The Business Case for Getting This Right 

Proper AI governance is becoming increasingly important for law firms. Clients are starting to ask questions about how their data is protected when firms use AI tools. Some are including AI governance requirements in their vendor assessments. 

Additionally, regulatory guidance around AI use in legal practice continues to evolve. Firms that implement strong governance early will be better positioned to demonstrate compliance and responsible AI use. 

From a practical standpoint, implementing governance correctly from the beginning is more efficient than retrofitting controls later. It also reduces the risk of inadvertent exposure during the pilot and expansion phases. 

 

Getting Started 

If your firm is considering Copilot Studio or wants to better govern existing implementations, we’d recommend starting with an assessment of your current environment and governance needs. 

We offer a 30-minute consultation to review your situation and discuss potential next steps. This typically covers your current Copilot usage, data sensitivity requirements, and governance gaps that should be addressed.
