Greenmask vs Ubiq Dynamic Data Masking

Greenmask is a free, open-source utility for logical database backups, anonymization, synthetic data generation, and restoration. It currently supports PostgreSQL, with MySQL, MongoDB, and other database support in development. Transformations can be deterministic or random, use dynamic parameters, mask data, or apply custom rules based on domains. Configuration validation can show warnings and data or schema differences, and transformation settings can be inherited across partitions of partitioned tables. Greenmask stores backups in local directories or S3-like remote storage. It supports parallel dumping and restoration, as well as parallel compression with pgzip. Its logical-dump approach does not require changes to the existing database schema, and dumps can be restored with pg_restore. CI/CD integration can automate anonymization and restoration. Greenmask runs on Linux and macOS and can be self-hosted on premises. Installation options include an install script, Docker, Homebrew, or building from source; the install script works on Linux and macOS, while Windows is not supported yet. A Docker Playground with sample databases provides a sandbox for trying the utility. The maker offers paid custom development for urgent or enterprise-specific feature requests.

Ubiq Dynamic Data Masking protects sensitive data by determining at runtime what a requesting identity receives. Depending on the identity, application, service account, API, or workflow, the same value can appear as cleartext, masked, tokenized, format-preserving protected, or encrypted data. Sensitive values can remain protected at rest while policy determines their runtime form. Ubiq supports both permanent masked copies for development, test, vendor, and analytics use and runtime decisions for production access. Connections include SDKs, APIs, SQL UDFs, and database and data warehouse integrations; its catalog lists 49+ integrations, including PostgreSQL, MongoDB, Snowflake, Databricks, and Tableau. Ubiq says it deploys inside the customer’s environment, does not operate as a masking proxy between applications and databases, and can protect data without schema changes where applicable. Customers can use their own HSM or KMS to retain key control. Enterprise Edition pricing is usage-based through a private offer, and additional AWS infrastructure costs may apply. A 30-day trial is listed; there is no free plan.
