Overexposed: Why Your Collaboration Tools Might Be Your Biggest Data Risk

Microsoft Teams, SharePoint, and OneDrive make collaboration easy.

But with ease comes exposure......

The Most Common Data Risks We See

• Guests with permanent access to sensitive Teams

• Private channels hiding file sprawl

• SharePoint sites with broken inheritance

• External sharing links that never expire

• DLP policies that exist - but don’t cover key repositories

These aren’t breaches. They’re overlooked defaults — and they’re everywhere.

Collaboration Isn’t Just Productivity - It’s Governance

When “every user is a data owner,” the risk scales with usage:

• Sharing becomes invisible

• Access boundaries dissolve

• No one knows what’s public - and what isn’t

This is why data governance is no longer optional.

You Can’t Secure What You Haven’t Scoped

Our Health Checks uncover:

• Overexposure risks

• Poorly scoped retention policies

• Inconsistent labelling

• Shadow access from historic Teams or migrations

  
  

Your collaboration tools are working - But are they secure?

The Data Health Check evaluates how your business-critical information is accessed, shared, and protected across SharePoint, OneDrive, and Exchange Online. It helps you identify data exposure risks, optimise DLP and sensitivity labels, and align with compliance obligations.
