Edit the Structured Data Settings

Configure the Enterprise Data Loss Prevention (E-DLP) structured data settings to control clustering behavior for structured data detection.
On May 7, 2025, Palo Alto Networks is introducing new Evidence Storage and Syslog Forwarding service IP addresses to improve performance and expand availability for these services globally.
You must allow these new service IP addresses on your network to avoid disruptions for these services. Review the Enterprise DLP Release Notes for more information.
Where Can I Use This?What Do I Need?
  • NGFW (Managed by Panorama or Strata Cloud Manager)
  • Prisma Access (Managed by Panorama or Strata Cloud Manager)
  • Prisma Browser
  • Enterprise Data Loss Prevention (E-DLP) license
    Review the Supported Platforms for details on the required license for each enforcement point.
Or any of the following licenses that include the Enterprise DLP license
  • Prisma Access CASB license
  • Next-Generation CASB for Prisma Access and NGFW (CASB-X) license
  • Data Security license
Enterprise Data Loss Prevention (E-DLP) uses clustering to detect sensitive data in structured documents such as spreadsheets and CSV files. Clustering groups instances of sensitive data that are close to each other and elevates a detection to High Confidence when six or more detections of the same type appear in a row or column, even without a proximity keyword in a header row. This enables Enterprise DLP to identify sensitive data in structured documents that don't have header rows with column names due to error or malicious intent.
However, if the underlying data pattern itself produces false positives, clustering can amplify those inaccuracies across an entire column. Clustering can also produce incorrect results when a single column contains values of multiple data types. Configure the structured data settings to control clustering behavior for your Enterprise DLP tenant and reduce false positives in structured data detection.
  1. Log in to Strata Cloud Manager.
  2. Select ConfigurationData Loss PreventionSettingsStructured Data.
  3. Enable or disable Header Prediction.
    Header prediction is enabled by default.
    Clustering is a form of header prediction: when Enterprise DLP detects a cluster of six or more detections of the same data type in a row or column, it predicts that the document was intended to have a header for that row or column and elevates those detections to High Confidence. This enables Enterprise DLP to identify sensitive data in structured documents that lack header rows due to error or malicious intent.
    Disabling header prediction also disables clustering.
  4. Enable or disable Enforce Data Uniformity.
    Enforce data uniformity is enabled by default.
    When enabled, Enterprise DLP attempts to predict the header only when the percentage of similar values in a column exceeds the configured Minimum Required Data Uniformity threshold. This directly controls when clustering can elevate detections to High Confidence; clustering only triggers when data uniformity in the row or column meets or exceeds the threshold. This prevents false positive header predictions and clustering in columns that contain mixed data types.
  5. (Optional) If you enabled data uniformity enforcement, configure the Minimum Required Data Uniformity percentage (default is 85%).
    The minimum required data uniformity threshold defines the minimum percentage of similar values required in a column before Enterprise DLP predicts a header for that column.
    Palo Alto Networks recommends using the default percentage to minimize false positive detections and maximize true positive detections. Modifying the Minimum Required Data Uniformity threshold does the following:
    • Increasing the threshold requires a higher percentage of similar values in the column before Enterprise DLP predicts a header. This can further reduce false positive detections but might prevent some detections from being elevated to High Confidence in columns with some variation in data.
    • Decreasing the threshold allows Enterprise DLP to predict a header even when the column contains more non-matching values. This increases detection coverage but might produce more false positive detections.
  6. Save your structured data settings.
