- Tools & Best Practices
Quick Summary
Microsoft 365’s ease of sharing can lead to oversharing, risking sensitive data exposure. Organizations often lack visibility into what users are sharing, with no centralized reporting available. Tenfold offers the first Identity Governance solution that provides access reviews for shared content, helping organizations regain control over their data sharing practices.
The Securityish Brief
Microsoft 365 is widely used for cloud collaboration, with Microsoft Teams boasting 320 million active users. However, the convenience of sharing can result in oversharing, where sensitive documents are shared longer than necessary or with too many people. This poses significant security risks, as organizations may lose track of who has access to what information.
Examples of oversharing include freelancers retaining access to files after a project ends, or sensitive documents remaining accessible in Teams channels after team changes. These scenarios highlight the potential for accidental data leaks or malicious data exfiltration.
Tenfold is the first solution to offer in-depth access reviews specifically for shared content in Microsoft 365. It provides visibility across Teams, OneDrive, and SharePoint, allowing organizations to monitor and manage what users are sharing.
