Confident Licensing: Microsoft’s Approach to Secure AI Access

Cybersecurity Awareness Month

As businesses increasingly turn to AI to enhance productivity, Microsoft Copilot stands out as a transformative tool. Yet, with powerful capabilities comes a critical need for robust data protection.

One often underestimated factor in AI adoption is licensing, determining who has access, what permissions they hold, and how those privileges are safeguarded.

This blog delves into how Microsoft’s licensing structure plays a pivotal role in ensuring security, compliance, and governance when deploying AI solutions like Copilot within Microsoft 365.

The Critical Link Between Licensing and Security

Licensing goes beyond unlocking features, it’s a cornerstone of governance. Microsoft’s licensing framework is designed to ensure that AI capabilities are accessed only by authorised users, with controls that align tightly with enterprise-level security and compliance standards.

Key Points:

• Copilot access is gated by licensing: Only users with eligible Microsoft 365 licenses (e.g., E3/E5 + Copilot add-on) can use Copilot.

  
  

• Security features scale with licensing tiers: Higher tiers unlock advanced security tools like Microsoft Purview, Defender for Endpoint, and Conditional Access.

Licensing Tiers and Their Security Implications

License Tier	Copilot Access	Security Features
Microsoft 365 E3	Limited (requires add-on)	Basic compliance, MFA
Microsoft 365 E5	Full access with add-on	Advanced threat protection, DLP, Purview
Copilot for Microsoft 365	Requires E3/E5 base	AI-powered productivity with enterprise-grade security

Highlights:

• E5 + Copilot gives organisations full control over data classification, auditing, and AI usage.

  
  

• Purview integration ensures sensitive data is protected, even when used by Copilot.

How Microsoft Protects AI Tools

Microsoft uses a layered approach to secure AI tools:

1. Identity & Access Management

   • Azure AD enforces role-based access and MFA.

   • Conditional Access policies restrict Copilot usage based on location, device, and risk level.

     
     

2. Data Protection

   • Microsoft Purview enables labelling and encryption of sensitive data.

   • Copilot respects these labels and avoids surfacing protected content.

     
     

3. Audit & Compliance

   • Admins can monitor Copilot usage via Microsoft 365 audit logs.

   • Data used by Copilot is not stored or used to train foundation models.

Proven Strategies for Licensing & Security

• ✅ Review your licensing strategy: Ensure users who need Copilot have the right base licenses and add-ons.

• ✅ Enable security features: Use Purview, Defender, and Conditional Access to protect AI interactions.

• ✅ Educate users: Train employees on what data Copilot can access and how to use it responsibly.

• ✅ Monitor usage: Use audit logs and reporting tools to track Copilot activity and flag anomalies.

Assurance Through Access Management

Licensing isn’t just a checkbox, it’s a security strategy. By aligning your Microsoft 365 licensing with robust security practices, you can unlock the full potential of AI tools like Copilot while keeping your data safe.
