As most organizations share their confidential details during testing and developing, it is necessary to protect this information from getting into the wrong hands. Most often these details need to be shared with developers and others while providing production support for upgrades, training, outsourcing etc. As a result there is a great risk of this data being used for unlawful activities.

Test data management helps in protecting data in less secure environments. It has several methods to protect the data before it is shared with the developers. Its option of copying only the required data makes the database smaller thereby requiring only less storage space.
Test data management is therefore very helpful in protecting data in less secure environments.
