Enables harnessing the power of Copilot without sacrificing data security or compliance

Sentra, the global leader in cloud-native data security for the AI era, launched its comprehensive solution for securing Microsoft 365 Copilot Security, enabling organizations to adopt Copilot with confidence while staying compliant and safeguarding sensitive enterprise data. The solution allows organizations to prevent overexposure of sensitive data of employees and other users, discover who has access to sensitive and confidential data, and label files automatically with an integration to Microsoft DLP for M365 Copilot, ensuring Copilot adoption meets enterprise security and compliance standards.

Microsoft 365 Copilot’s Efficiency Comes with New Data Security Challenges

Microsoft 365 Copilot, embedded across applications like SharePoint, OneDrive, and Teams, streamlines business processes and enhances productivity, but also presents new data exfiltration and overexposure risks. According to recent research, over 15 percent of business-critical files are exposed due to oversharing and excessive permissions. These risks are compounded by redundant, unused, stale, and trivial (RUST) data, over-permissioned access, and incomplete sensitivity labeling – all of which can amplify Copilot’s exposure surface and ‘blast radius’.

With Sentra solution for Microsoft 365 Copilot, organizations can leverage Sentra’s platform capabilities to fully address the unique data risks with:

• Discovery and Classification – cataloging and classifying all the sensitive and critical data in Microsoft 365 (including SharePoint, OneDrive and Teams)
• Data Access Governance – mapping who has permission to every file with sensitive and critical data, enabling different views and filters to determine over-permissioning and enforce least privilege, and allowing sanitization and removal of unnecessary exposure
• Automatic Labeling – automatically apply Microsoft Purview Information Protection (MPIP) sensitivity labels based on flexible custom business logic, identify and fix missing or incorrect labels, and integrate with Microsoft Purview DLP for Copilot
• Continuous Monitoring and Remediation – Continuously monitoring and automatically remediating missing or incorrect MPIP sensitivity labels, ensuring consistent and accurate M365 Copilot DLP governance.
