 Synchronize Production NOSQL and SQL data to Standalone instances for Data scientists or other purposes. A **Go-based** tool to synchronize MongoDB or SQL data from a **MongoDB replica set** or **sharded cluster** or production SQL instance to a **standalone instance**, supports initial and incremental synchronization, including **indexes** with change stream monitoring.
 
 > [!NOTE]
-> Sync now supports MongoDB, MySQL, PostgreSQL, MariaDB, and Redis. Next, `Sync` will support Elasticsearch.
-> `Sync` is **PII** proof.
+> - Sync now supports MongoDB, MySQL, PostgreSQL, MariaDB, and Redis. Next, `Sync` will support Elasticsearch.
+> - `Sync` is **PII** proof, meaning you can select specific records, keys, columns from your source databases, and sync them into target databases using one-way **encryption** or **masking** methods.
 
 ## What is the problem
-Let's assume you have a mid to big-size SaaS platform or service with multiple tech teams and stakeholders. Different teams have different requirements for analyzing the production data independently. However, the tech team doesn't want to allow all these stakeholders direct access to the production databases due to security and stability issues.

 ## A simple one-way solution
 Create standalone databases outside of your production database servers with the same name as production and sync the production data of the specific tables or collections to the standalone database. **Sync** will do this for you.
