Data loss prevention (DLP) tools detect and control the movement of sensitive information such as credit card numbers, personal data, and confidential documents.

What DLP can do

– Detect sensitive content in emails, files, and chat messages

– Warn users before they share it

– Block or encrypt risky transfers

– Prevent copying to USB drives or personal cloud storage

– Log events for audits and investigations

Where it applies

– Email and Teams messages

– SharePoint and OneDrive files

– Endpoints, including USB, printing, and clipboard

– Cloud apps and web uploads

Business Premium includes DLP and sensitivity labels, so you may already own useful tools. Combined with sensitivity labels, you can mark documents as “Confidential” and apply protections automatically.

How to start

1. Know your data: where is personal and confidential information stored?

2. Classify: create a simple scheme (Public, Internal, Confidential)

3. Start in audit mode: see what would be flagged before blocking anything

4. Add user tips, so people learn from policy hints

5. Tune policies to reduce false alerts

6. Enforce gradually

Why it matters in Quebec

Law 25 requires reasonable safeguards for personal information. DLP is one practical control that shows you are taking steps to prevent leaks.

Common mistakes

– Turning on strict blocking immediately, which disrupts work

– Writing too many policies

– Not training staff

– Never reviewing alerts
