As Microsoft Copilot becomes more available across Microsoft 365, a lot of organizations are eager to roll it out and boost productivity. Before enabling Copilot for your users, there’s a crucial step to consider: making sure your data environment is ready with Microsoft Purview.
Here’s what you should keep in mind before introducing Copilot to your organization.
1. Understand What Copilot Can Access
Copilot is designed to pull and summarize data from your Microsoft 365 apps—SharePoint, OneDrive, Teams, Outlook, and more. This convenience also means it can surface sensitive or regulated content to a much wider audience if access isn’t managed carefully.
Ask yourself: If Copilot can see it, can your users see it too?
2. Review and Tighten Data Access Controls
Take time to review your current permissions and sharing settings. Many companies discover that “permission creep” has made some files and sites more accessible than intended, especially with older SharePoint sites or Teams channels.
Use Purview to identify overly broad sharing, remove unnecessary guest access or public links, and make sure access matches business needs, not just convenience.
3. Implement and Validate Sensitivity Labels
Copilot respects sensitivity labels managed by Purview. If you have a solid labeling policy in place, you’re already ahead. If not, this is the right moment to roll one out.
Label sensitive content, like “Confidential” or “Restricted,” set up auto-labeling for files with PII or financial data, and make sure labels are being used consistently.
4. Expand Your Sensitive Information Types (SITs)
A lot of organizations start with basics like Social Security and credit card numbers, but it helps to add industry-specific or custom types before Copilot goes live. Consider HR files, intellectual property, or health information.
Review and expand your Sensitive Information Types in Purview, and test labeling against your real data.
5. Map Out Copilot Scenarios and Risks
Meet with your stakeholders and discuss how people plan to use Copilot, and where data exposure could become a risk. Make sure everyone understands what Copilot will show, based on the permissions and labeling in place.
6. Educate Users and Build a Rollout Plan
Well-informed users are your first line of defense. Give your staff simple guides or short training sessions about what Copilot can do, how labeling works, and what to do if they find data they shouldn’t access.
Set up a feedback channel for any Copilot-related concerns.
7. Monitor and Adjust After Launch
Once Copilot is live, keep an eye on how data is being accessed and labeled through Purview. Be ready to update your policies as your organization’s needs change.
Final Thoughts
Copilot can be a game-changer for productivity, but only if it’s introduced with the right security and compliance foundations. Microsoft Purview isn’t just a checkbox, it’s a key part of launching Copilot in a way that’s both secure and valuable. Take the time to get it right, and your Copilot experience will be smoother, safer, and more effective.
If you’re considering Copilot for your organization, now is the time to review your Purview policies and make sure you’re ready for what’s next.
