12 Best Data Masking Tools and Software in 2025

Data Masking replaces authentic original data with structurally similar data that provides fake values. In simple terms, the original format of the data is retained while the values are changed. 

Values change through methods such as encryption, shuffling, substitution, etc. Data masking makes it nearly impossible to obtain or reverse engineer the original data; hence, it is a one-way process. 

Let us discuss the best data masking tools in the market that will make your task easier.
