Sentra, the global leader in cloud-native data security for the AI era, unveiled its comprehensive solution for Microsoft 365 Copilot security. The new platform empowers organizations to confidently adopt Copilot while maintaining compliance and protecting sensitive enterprise information. Sentra’s solution enables businesses to prevent overexposure of employee and user data, identify who has access to confidential information, and automatically label files through seamless integration with Microsoft DLP for M365 Copilot ensuring security and compliance standards are consistently met.
Microsoft 365 Copilot Boosts Productivity, Brings New Data Security Challenges
Microsoft 365 Copilot, embedded within applications like SharePoint, OneDrive, and Teams, enhances workflow efficiency and productivity. However, its deployment introduces potential data exfiltration and overexposure risks. Research indicates that more than 15 percent of business-critical files are exposed due to oversharing and excessive permissions. These vulnerabilities are further amplified by redundant, unused, stale, and trivial (RUST) data, over-permissioned access, and incomplete sensitivity labeling, increasing Copilot’s exposure surface and potential ‘blast radius.’

Sentra Delivers Complete Data Visibility and Governance for Copilot
Sentra’s Microsoft 365 Copilot solution provides organizations with end-to-end data risk management through:
-
Discovery and Classification: Cataloging and classifying sensitive and critical data across Microsoft 365, including SharePoint, OneDrive, and Teams.

Data Access Governance: Mapping permissions for every file containing sensitive data, enabling advanced views and filters to detect over-permissioning, enforce least privilege, and remove unnecessary exposure.
-
Automatic Labeling: Applying Microsoft Purview Information Protection (MPIP) sensitivity labels automatically based on flexible custom business logic, correcting missing or incorrect labels, and integrating with Microsoft Purview DLP for Copilot.
-
Continuous Monitoring and Remediation: Continuously auditing and automatically correcting missing or inaccurate MPIP labels, ensuring consistent DLP governance for M365 Copilot.
“Microsoft 365 Copilot is quickly becoming an integral part for all organizations’ workflows, which shouldn’t come at the expense of data leaks or overexposure of data,” said Yair Cohen, VP Product and Co-founder of Sentra. “Sentra’s data security platform gives security teams full visibility and control over their data assets in Microsoft 365 so their organizations have the freedom to innovate without unnecessary risks.”
