Data masking tackles security issues head-on by tweaking data's actual digits and letters, maintaining confidentiality. It alters data values while preserving the original format, creating a pseudo-version for testing, research, or training. Developers use data masking to curb security risks during the development and testing phases. Some companies leverage masked data for employee onboarding, allowing skill practice without exposing critical assets.
What are the benefits of data masking?
It aids companies in adhering to data privacy regulations and compliance standards, acting as a robust defense against threats like data loss and breaches. Cost-effective compared to pricier encrypted solutions, masked data retains the functional properties of the original without revealing its true value.
There are different ways and challenges in masking data. Check out the top 5 best data masking software in 2023 outlined below to create realistic and structurally similar datasets:

DATPROF's Test Data Management Platform enables anonymization of data through data masking and synthetic data generation, ensuring the necessary test data for execution.
Features
Test data management involves data masking to create and provide realistic test data for different use cases like QA, development, testing, and training. The data masking software of DATPROF can protect privacy-sensitive data by anonymizing it through data obfuscation or synthetic data generation. Outlined below are its main features:
Data Masking Techniques
Data masking involves reusing or modifying data in databases. DATPROF masks by implementing the following techniques:
Shuffle: This involves taking the distinct values of one or multiple columns and rearranging them to create new name combinations of data.
Scramble: This replaces characters by x and numbers by 9 to make the data unrecognizable.
Random Lookup: This technique uses a reference table to replace values by randomly selecting data from another table.
Custom Expression: Users can leverage the flexibility of custom expressions instead of standard functions to alter the composition of real datasets.
Blank: This technique removes a column from a table to hide the dataset. This is only recommended for columns not used in testing.
First Day in Month/Year: This alters the date of birth to the first month or year, making it harder to trace the data to a specific person.
Value Lookup: This technique uses a reference table to anonymize the values of the data. It requires a reference key to locate the original data.
Synthetic Test Data Generation
In cases where data masking techniques fall short, DATPROF employs 50+ built-in generators to produce synthetic test data. This artificial data replaces privacy-sensitive information in a testing environment, ensuring compliance with data protection regulations and meeting specific testing requirements.
Multi-database Masking
DATPROF achieves consistent data masking across multiple tables through deterministic data masking. It ensures uniform data masking, replacing values consistently across all sources and applications, whether within the same row, table, schema, or between instances, servers, and database types. It can replace a value in a column with the same value, like modifying every dataset containing "Lynne" into "Denise".
DATPROF understands the importance of data masking to protect privacy-sensitive data and maintain compliance with privacy laws. Leverage its data masking software to have better data protection and produce test data for different teams.

Overview
Mage takes care of the data privacy and security needs of enterprises so they can focus on growing their business. It is an industry-leading solution, recognized by Gartner Peer Insights as the Customers' Choice for three consecutive years. It has also received its ISO/IEC 27001, proving it abides by the international standard for information security management systems.
Features
Static Data Masking
Static data masking replaces sensitive data with fake but realistic data. Mage offers more than 60 different anonymization methods so enterprises can secure their data effectively. These methods balance protection and performance, promising consistent results across applications and data stores so businesses can maintain referential integrity for maximum usability.
The Mage platform also features a variety of NIST-approved encryption and tokenization algorithms, which safeguard the sensitive value of data. Encryption supports structured and unstructured fields and even databases that aren't stored in multiple systems. Enterprises can use this method of anonymization to protect files and data that are exchanged with third parties.
On the other hand, tokenization replaces the data with a random string of values (or tokens) instead of being modified by an algorithm. It preserves the format of the data, maintaining high security and usability.
Enterprises can also minimize the risk of re-identification by using the Mage Identities masking method. They can also generate a fake dataset using logic and AI without losing the attributes of the original data. The AI, together with natural language processing, can understand the context and discover sensitive data in unstructured fields or sensitive data deeply hidden in log files.
Dynamic Data Masking
Dynamic data masking of Mage provides 40+ anonymization methods, so enterprises have the flexibility to take control of sensitive data in production and non-production environments. They can mask sensitive data at application and database layers with customizable solutions.
The platform features rules within the product UI, which users can configure to activate role-based, user-based, program-based, and location-based access controls. These restrict or grant access to sensitive data. These authorization rules benefit companies with offshore offices, given they can control who can view the sensitive data based on a data classification-centric anonymization technique. Guaranteed the data remains secure in transit, at rest, or in use.
Mage also offers blended and hybrid data masking to address unique cases like cloud migration. Enterprises can leverage both to maintain the integrity of application clusters while migrating individual applications to the cloud without hassle. Their data remains secure both in the database and application layer.
