Greenmask vs Kron Database Access Manager

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.

Kron Database Access Manager is a paid, hybrid database security product that centralizes access control, query policy enforcement, activity monitoring, and audit reporting. Its SQL Proxy routes database queries through a control point that captures activity and applies rules while allowing users to keep their existing database clients and standard protocols. Administrators can restrict sensitive data access, discover items such as credit-card and personal-ID numbers, and apply dynamic masking to filtered results. Listed database platforms include Oracle, MSSQL, MySQL, PostgreSQL, Couchbase, Teradata, Cassandra, SAP HANA, and Hive; MongoDB support was added to the SQL Proxy in Kron PAM 3.9. SSO and MFA through the Kron JDBC Driver are listed for MySQL, PostgreSQL, Oracle, and Microsoft SQL Server. Session and query logging support compliance needs, and persistent logging failure causes the proxy to stop accepting new connections. Kron was founded in 2007 and is headquartered in Istanbul, Turkey. Pricing is available on request, and multitenant features require a Data Access Management license.
