Netwrix Data Classification automatically discovers and classifies sensitive and regulated data across file systems, Microsoft 365, SharePoint, Exchange, OneDrive, databases, and other cloud and on-premises environments. As a core component of Netwrix data security posture management (DSPM), it enables organizations to understand where sensitive data resides, who has access to it, and how it is exposed.

The solution uses advanced content analysis and customizable classification rules to identify personally identifiable information (PII), financial data, intellectual property, regulated records, and other sensitive content. Classification tags are written directly to files and metadata, enabling integration with data loss prevention solutions, access governance controls, and security monitoring tools.
Netwrix Data Classification also supports automated remediation workflows. Organizations can move sensitive files to secure locations, adjust access permissions, redact sensitive content, apply labels, and identify redundant, obsolete, and trivial (ROT) data for cleanup. By combining data discovery, effective permissions analysis, and automation, it helps reduce data exposure and strengthen compliance with regulations such as GDPR, HIPAA, and PCI DSS.
Key use cases
• Discover sensitive and regulated data across hybrid environments
• Identify overexposed data by analyzing effective permissions
• Remediate data risk with automated policy actions and workflows
• Identify and clean up redundant, obsolete, and trivial (ROT) data
• Protect intellectual property with content-based classification and tagging
• Support compliance with predefined classification rules aligned to regulatory standards
• Strengthen data loss prevention effectiveness with embedded classification tags

| Isms Manager & Information Systems Security at a financial services firm with 201-500 employees | 5.0 | I find Netwrix Data Classification intuitive, cost-effective, and crucial for automated document classification and compliance, superior to Microsoft's tiered offerings. I seek better enforcement of confidential labels for shared documents, and prefer no AI for security execution. |
| Business Development Manager at BAKOTECH | 4.5 | I find Netwrix Data Classification to be a flexible, scalable, and cost-effective solution for auditing and data classification. Its user-friendly design and predefined rules simplify tasks, though interface complexity and licensing structure could be improved for better accessibility. |
| Director at IP Infotech Pvt. Ltd. | 4.5 | I found Netwrix Data Classification to be effective for network data discovery and security, providing an accurate data framework. However, it falls short on endpoint data classification, needing improvements in user-friendliness and faster technical support response times. |
