Jasper Oosterveld, a Microsoft MVP and Data Security Consultant based in the Netherlands, works at Rubicon with clients to implement Microsoft Purview and Microsoft 365. Jasper is passionate about sharing his expertise and enthusiasm for Microsoft products.
Implementing Microsoft Purview isn’t just about turning on labels and policies. It’s about making them work across SharePoint, OneDrive, Teams, and Copilot. In this session, Microsoft MVP Jasper Oosterveld will share lessons from real customer implementations across highly regulated and complex environments. You’ll gain clarity on how labels, DLP, and retention are being put into place, how to validate and roll them out over time, and how Purview fits into broader Copilot and GenAI readiness. If your goals include keeping data protected as Copilot and AI become part of everyday work—and doing it without adding friction—then this session is for you.
Read moreYour Microsoft 365 governance strategy may look solid on paper, but Copilot, generative AI, and agents are testing whether it actually holds up in practice. In this session, Microsoft MVP Jasper Oosterveld will draw from his real Purview and Copilot projects and walk through how to reassess governance in an AI-enabled tenant. Learn how to look at access, sharing, lifecycle, and data protection using Microsoft-native tools like SharePoint Advanced Management, the Teams and SharePoint admin centers, and Microsoft Purview.
Read moreCopilot was already running. A selection of employees used it every day. Then the organization hit the brakes: no broader rollout until sensitivity labels were in place for everyone. That’s where I came in. This session tells the story of that assignment. It’s not only about sensitivity labels, but also about DLP and retention labels. Customer information, employee files and project documentation all sat side by side in Microsoft 365, within Copilot’s reach for anyone with access. I share the approach we followed, from the first workshop to the go/no-go moment, and what we ran into along the way. Like encrypted labels that worked fine internally but broke as soon as external parties got involved. The technology was only half the work. Employees needed to know which label to pick and why, so adoption got as much attention as configuration. Managers and the security team needed to see whether labels were actually used and where the risks were, so monitoring and reporting were part of the plan from day one. In parallel we delivered a new set of retention labels, both to stay compliant and to keep Copilot away from outdated information. We also set up DLP in monitoring mode, to see which sensitive data and labels show up in Copilot interactions before blocking anything. You’ll leave with the plan, the pitfalls and an honest list of what I’d do again and what I’d never do again.
