Data Masking FAQ

Data masking is a security technique that creates a realistic, but non-sensitive, version of an organization's data. It replaces confidential information with fictional data, allowing it to be used for development, testing, or training without exposing real, sensitive details.

Data masking works by obfuscating sensitive data using techniques like substitution, shuffling, and encryption. The process replaces original data with an irreversibly altered version that maintains the integrity and format of the original, but is not the real information.

The primary benefit is enhanced data security. Data masking protects sensitive information from unauthorized access, reduces the risk of data breaches, and helps organizations comply with data privacy regulations like GDPR and HIPAA. It allows for safe use of data in non-production environments.

Data masking is used in non-production environments such as development, testing, and training. It is ideal for situations where real, sensitive data is not necessary, but a realistic dataset is required to ensure applications and systems function correctly.

No, they are different. Data encryption scrambles data into an unreadable format that can be decrypted with the correct key. Data masking permanently alters data to create a fake version that cannot be decrypted back to its original form.
