Secure Your Copilot: Sentra’s Zero-Trust Data Protection
▼ Summary
– Sentra launched a solution to secure Microsoft 365 Copilot, helping organizations adopt it while maintaining compliance and protecting sensitive data.
– Microsoft 365 Copilot enhances productivity but increases data risks, including oversharing and overexposure of critical files.
– The solution provides data discovery and classification, cataloging sensitive information across SharePoint, OneDrive, and Teams.
– It enables data access governance by mapping file permissions and enforcing least privilege to reduce unnecessary exposure.
– Sentra offers automatic labeling and continuous monitoring to ensure accurate sensitivity labels and integrate with Microsoft DLP for Copilot.
Businesses embracing Microsoft 365 Copilot now have a powerful new ally in securing their sensitive information. Sentra has introduced a specialized solution designed to protect enterprise data within Copilot environments, enabling companies to adopt the AI-powered tool with greater confidence while maintaining compliance and safeguarding confidential material.
This platform helps organizations prevent the overexposure of sensitive employee and user data, identify who has access to protected files, and automatically apply labels through integration with Microsoft’s Data Loss Prevention (DLP) tools. These features ensure that Copilot implementations align with strict enterprise security and regulatory requirements.
While Microsoft 365 Copilot significantly enhances workflow efficiency across applications like SharePoint, OneDrive, and Teams, it also introduces new vulnerabilities. Recent studies indicate that more than 15% of business-critical files are improperly shared or suffer from excessive permissions. These risks are worsened by redundant, outdated, or trivial data, over-permissioned user access, and inconsistent sensitivity labeling, all of which can expand Copilot’s potential exposure.
Sentra’s solution directly confronts these challenges by providing comprehensive data visibility and control. The platform delivers several core capabilities tailored for Copilot environments:
It begins with discovery and classification, systematically cataloging all sensitive and critical data stored across Microsoft 365 services. This foundational step ensures that no vulnerable information goes unnoticed.
Next, data access governance tools map permissions for every sensitive file, offering customizable views and filters to detect over-permissioned access. This enables organizations to enforce the principle of least privilege and remove unnecessary exposure.
The system also supports automatic labeling, applying Microsoft Purview Information Protection tags based on customizable business rules. It identifies and corrects missing or inaccurate labels and integrates directly with Microsoft Purview DLP to maintain consistent policy enforcement.
Finally, continuous monitoring and remediation ensure that sensitivity labels remain accurate over time, automatically addressing inconsistencies and supporting ongoing DLP governance for Copilot.
Yair Cohen, VP of Product and Co-founder at Sentra, emphasized the importance of balancing innovation with security. “Microsoft 365 Copilot is rapidly becoming essential to organizational workflows, but that shouldn’t mean compromising on data protection,” he noted. “Our platform gives security teams the visibility and control they need to innovate freely, without taking on unnecessary risk.”
