Stop Public Exposure of Sensitive Microsoft 365 Files Before It Spreads

You can’t fix what you can’t see. This holds true for any environment, and Microsoft 365 is no exception. With file sharing so deeply embedded into how teams work, it’s easy for sensitive data to end up publicly accessible, without security teams ever being looped in. 

Cyera is helping businesses reduce this risk by giving security teams a complete view of publicly shared Microsoft 365 files and the power to take those shares down immediately.

How Cyera Helps: Visibility and Control Over Public Access

In Microsoft 365, sharing files is fast and frictionless. A user selects “Anyone with the link can view,” sends the link off, and moves on. But over time, those links accumulate, bringing with them unnecessary exposure.

This isn’t a fringe issue. It’s commonplace, even among the world’s most regulated businesses. 

With Cyera, it’s not just about flagging exposures, it’s about making it easy to take action.

1. Discover Publicly Shared Files

Cyera scans Microsoft 365 to identify files shared with the “Anyone with the link” setting enabled. For each file, you get:

• File name and location
• Sensitivity and data classifications
• Sharing method and exposure status
• Whether the file is shared directly or inherits public access from a parent folder

Publicly shared sensitive files are highlighted automatically, so there’s no need to sift through everything manually.

2. Revoke Public Access in One Click

Once files are flagged, you can remove public sharing links directly within Cyera:

• Revoke access to individual files or take bulk action across multiple exposures
• Confirm changes with automated updates and remediation tracking

No admin center workarounds. No lag. Just fast, reliable cleanup in-platform.

3. Understand the Effect of Removing Access

Some files inherit public access from the folders they reside in. Cyera highlights when public access is inherited, giving your team the insight needed to understand the effect of removing access, before you act. This helps avoid unexpected disruptions and ensures you're remediating risk at the right level.

From Exposure to Resolution, Fast

Imagine discovering hundreds of publicly shared files, some with sensitive financial data, others with internal plans or customer records. Traditionally, remediating this would take weeks of investigation and coordination.

With Cyera:

• Sensitive, publicly shared files are highlighted automatically
• You see whether public access is direct or inherited
• You revoke access with confidence in just a few clicks

No guesswork. No delays. Just control.

Take Control of Microsoft 365 Public Sharing

Public links are easy to create and just as easy to forget. Over time, they create exposure your security team never intended. Cyera gives you the visibility to catch it, the context to understand it, and the control to shut it down.
