Sensitive Data Exposure Map
You think only five people have access to that sensitive folder. Turns out it’s fifty-seven, including one ex-intern and a mystery Gmail account. 1Security’s Data Exposure Map replaces assumption with proof, giving you the full picture of who can see what in Microsoft 365 and helping your organization protect critical data before it’s exposed.
What is the challenge?
Doing It with 1Security
Eliminate blind spots and map every layer of data exposure. 1Security gives customers a clear, centralized way to manage permissions and data security within Microsoft 365.
Centralized exposure view
See where sensitive Microsoft data is stored, who can access it, and how it’s shared across Teams, SharePoint, and OneDrive.
Live exposure alerts
Receive real-time notifications when new high-risk links or external shares appear, reducing vulnerabilities instantly.
Copilot readiness checks
Identify which files or chats may surface in Copilot results so you can secure AI usage before general availability.
Time-based exposure history
Review how access changed before incidents, helping security teams trace and manage potential risks faster.
Smart sensitivity mapping
Combine Purview labels with permission data to reveal genuine exposure and protect sensitive information with full context.
Compliance snapshots
Generate audit-ready reports that prove control and manage Microsoft 365 compliance efficiently.
Actionable insights
Remove risky shares, revoke stale accounts, or enforce identity-based access controls directly from the 1Security dashboard.
Solving It with Other Methods
Organizations often attempt to uncover Microsoft data exposure with native tools or manual audits, but results are fragmented and inconsistent.
