Redgate Data Masker review
A focused Windows tool for realistic SQL Server and Oracle data masking.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Redgate Data Masker is an on-premises database security tool for replacing sensitive information in SQL Server and Oracle databases with realistic anonymized data. It is intended for development, testing, and other non-production environments where teams need usable data without retaining sensitive values. A Windows graphical application handles masking-set configuration, while a command-line application supports automation for building and running those sets. The product is a strong fit for organizations working in Windows-based SQL environments and looking for a dedicated data-masking workflow.
Its standout capability is configurable masking. Rules support substitution, shuffling, table synchronization, and other transformations, allowing teams to shape replacement data around database relationships and testing needs. Rule, table, and run statistics provide reporting on masking activity, while column discovery and schema comparison tools help identify data and structural changes that may affect a masking set. This combination suits teams that need more than a one-off replacement process, particularly when masking routines must be maintained and automated over time.
Redgate Data Masker also fits Redgate-centered workflows through integrations with SQL Data Catalog and SQL Clone. Pricing is capacity-based and requires contacting Redgate, and the product does not have a free plan. Its platform scope is Windows, and its security coverage is deliberately narrow: data masking and audit reporting are central, while activity monitoring, access governance, and threat detection are not part of the listed capabilities. Choose it when realistic masked copies and repeatable SQL data preparation are the priority. Consider an alternative if you need broader database security controls, a non-Windows platform, or a tool centered on monitoring and governance.
