Data Loss Prevention With Teams & SharePoint

Sensitive information shared in Teams chats, channels, and SharePoint sites often escapes basic protections. Accidental external sharing, unmonitored file uploads, and overlooked chat messages can lead to compliance violations and data breaches. Many organisations lack tailored policies to safeguard credit card numbers, health data, or intellectual property across these platforms.

In this introductory session, Ben Stegink covers Data Loss Prevention (DLP) fundamentals in Microsoft 365, with a focus on Teams and SharePoint. He explains core concepts, policy creation in the Compliance Center, and extensions to Exchange, devices, on-premises systems, and Power BI.

What You Will Learn

• Core concepts of Data Loss Prevention (DLP) in Microsoft 365 and how it protects sensitive data
• Reasons to implement DLP, including types of sensitive information at risk and breach consequences
• Navigation of the Microsoft 365 Compliance Center and the DLP management console
• Steps to create and customize DLP policies tailored to organisational needs for Teams and SharePoint
• Application of DLP policies to Exchange Online for email protection alongside Teams and SharePoint
• Extension of DLP coverage to endpoints, on-premises repositories, and Power BI datasets
• Best practices for policy configuration and monitoring to effectively safeguard your environment

Key Takeaways

1. Identify your sensitive data types first. Ben emphasises starting with common classifiers like financial data or PII before building policies, which simplifies setup and reduces false positives.
2. Use the Compliance Center for unified management. Access DLP policies via the Microsoft 365 Compliance Center under Data loss prevention, then select locations like Teams and SharePoint to apply rules consistently.
3. Test policies in audit mode. Deploy new DLP rules in audit-only mode to monitor potential blocks without disrupting users, allowing refinement based on real usage.
4. Combine with sensitivity labels. Pair DLP policies with Microsoft Purview sensitivity labels for proactive protection on files shared in Teams or stored in SharePoint.
