How to Deploy Microsoft Purview DLP for Copilot and Generative AI

Posted on 16 May 2026Updated on 16 May 2026by Nikki Chapple

Organisations adopting Microsoft 365 Copilot and generative AI are facing a common challenge. Data is no longer static. It is constantly moving, reused, and now being surfaced and generated by AI.

This changes the risk profile.

The questions I hear most often are:

What are the real data security risks with AI?
Which controls actually make a difference?
How do we deploy them effectively in Microsoft Purview?

This guide builds on my ECS 2026 session and focuses on the controls that provide the greatest practical value. It cuts through the noise and shows how to use Microsoft Purview DLP for Copilot and generative AI, with a practical approach to reducing real-world data leakage risk across both internal and external AI tools.

Container Sensitivity Labels: The Purview “Hack” That Fixes Copilot Oversharing Fast

Posted on 16 May 2026Updated on 16 May 2026by Nikki Chapple

Introduction: Oversharing Starts Before a Single File Exists

Copilot oversharing is one of the most misunderstood risks in Microsoft 365. In reality, it often starts before a single file is uploaded.

It begins when Microsoft Teams, SharePoint sites, and Microsoft 365 Groups are created using generic tenant-wide defaults.

In an AI-enabled world, those overly permissive defaults become significantly more dangerous because Microsoft 365 Copilot operates within existing permissions.

Copilot does not create access.

It reveals it.

How to Configure Container Sensitivity Labels in Microsoft Purview (Step-by-Step)

Posted on 15 May 2026Updated on 16 May 2026by Nikki Chapple

Microsoft Purview container sensitivity labels allow organisations to apply consistent, risk-based collaboration and access controls across Microsoft Teams, Microsoft 365 Groups, and SharePoint sites without relying on manual decisions at the point of creation.

Instead of users or administrators deciding security settings each time a workspace is created, container sensitivity labels enforce governance automatically based on collaboration risk.

This is one of the most effective ways to reduce Microsoft 365 Copilot oversharing risk because Copilot surfaces only what users already have access to.

If access controls are overly broad, AI exposure becomes overly broad.

AI tools like ChatGPT, Bard, and Claude are transforming the workplace. From customer service to content creation, employees are increasingly turning to them as productivity boosters. But with this innovation comes a challenge:

⚠️ How do you protect sensitive company data from being unintentionally exposed, while still enabling the benefits of AI?

The answer: the Microsoft Purview Browser Extension — a lightweight, privacy-first tool that gives organizations visibility and control over browser activity without becoming intrusive. When combined with Endpoint DLP, Insider Risk Management (IRM), and Data Security Posture Management (DSPM) for AI, it provides a powerful way to govern risky behavior, including shadow AI.

How to add sensitivity labels to your existing Microsoft 365 Groups, Teams and SharePoint sites

Posted on 23 April 2023Updated on 11 August 2024by Nikki Chapple

How to add sensitivity labels to my existing groups, teams and sites? This was a question I was asked after one of my previous blogs on how to protect your groups, Teams and sites. If you only have a small number of groups, teams and sites, then it is easy to manually add the container sensitivity label to each group team or site. But what happens when you have thousands of groups, couples and sites?

Fortunately, there is a way to automate this task using PnP PowerShell. In this blog post, I will walk you through the steps needed first to analyze your existing groups, teams and site and then to programmatically apply container sensitivity labels to your existing Teams, Groups, and Sites in Microsoft 365 to help you protect your important data from unauthorized access and accidental sharing.
