Balancing Copilot Productivity with Data Security

Microsoft 365 Copilot enhances efficiency across SharePoint, OneDrive, Teams, and other Microsoft 365 applications, streamlining workflows and boosting productivity. However, these benefits come with new data security challenges. Research shows that over 15% of business-critical files are exposed due to oversharing or excessive permissions. Risks are further amplified by redundant, unused, stale, and trivial (RUST) data, unchecked access privileges, and incomplete sensitivity labeling, potentially expanding Copilot’s exposure footprint.

Comprehensive Data Control with Sentra

Sentra’s solution offers organizations full visibility and control over their Microsoft 365 Copilot environment through several key capabilities:

  • Discovery and Classification: Identifies, catalogs, and classifies sensitive and critical data across Microsoft 365, including SharePoint, OneDrive, and Teams.
  • Data Access Governance: Maps permissions for all sensitive data, highlights over-permissioned files, enforces least-privilege access, and enables remediation of unnecessary exposure.
  • Automatic Labeling: Applies Microsoft Purview Information Protection (MPIP) sensitivity labels automatically based on customizable business logic, corrects missing or inaccurate labels, and integrates seamlessly with Microsoft Purview DLP for Copilot.
  • Continuous Monitoring and Remediation: Ensures ongoing governance by monitoring MPIP labels and automatically correcting errors, maintaining consistent compliance across Microsoft 365.

“Microsoft 365 Copilot is rapidly becoming essential to modern workflows, but organizations shouldn’t compromise on data security,” said Yair Cohen, VP Product and Co-founder of Sentra. “Our platform provides complete visibility and control over sensitive Microsoft 365 data, allowing teams to innovate safely without risking data leaks or overexposure.”
