Data masking tools help you use your data for development, testing, analytics, and other such applications while rendering it useless for external threats. As a result, you can minimize the impact of data breaches.

According to Gartner, using data masking tools can “minimize the footprint and propagation of sensitive data (or its viewing) without extensive custom development.”

This article presents the most widely used data masking tools for small, mid-sized, and large organizations. These tools have been featured on popular review portals such as Gartner and G2.

The Delphix data platform offers an automated approach to data masking in non-production environments. It masks sensitive information (social security numbers or credit card information) with realistic data so that it can be used for development, testing, QA, and analytics.

Even though the masking algorithms are pre-configured, you can adapt them to meet the security requirements specific to your organization.

Moreover, the platform comes with an intuitive UI and has a no-code/low-code setup, thereby simplifying the installation process.

What are the main capabilities of Delphix’s data masking solution?

  • Delphix performs end-to-end data masking by identifying sensitive data and automatically masking it.
  • Delphix is compliant with data privacy standards, such as GDPR, CCPA, PCI DSS, and HIPAA.
  • You can choose to tokenize the sensitive data instead of masking to reverse the obfuscation. The automatic masking is irreversible.
  • The platform supports all types of applications in the data ecosystem and multi-cloud environments.

Immuta’s Universal Data Access Control solution offers dynamic data masking and anonymization. The product preserves the confidentiality of sensitive data using advanced privacy-enhancing technologies (PETs), as per HIPAA.

What are the main capabilities of Immuta’s Universal Data Access Control solution?

Immuta’s solution enables dynamic data masking and uses several masking techniques. The two prominent techniques also referred to as dynamic PETs include:

  • K-anonymization: Also referred to as ‘hiding in the crowd’, this technique hides an individual’s data within a larger group. So, the sensitive information could belong to any of the individuals in the group. Immuta automates the entire process to avoid a manual or code-based approach to anonymization.
  • Differential privacy: This technique adds noise every time a query is run. The noise gets added depending on the sensitivity of the query. So, data teams can share data without worrying about the confidentiality of sensitive data.

Informatica offers the Persistent Data Masking software that copies sensitive data and uses the techniques of anonymization and encryption to safeguard its privacy. These copies help you carry out testing, development, analytics, and other similar functions using realistic data.

The software applies several masking algorithms (substitution, randomization, or nullification) and techniques specific to PII data (credit cards or financial information). It uses a NIST-standard FPE transformation to enable reversible masking.

What are the main capabilities of Informatica’s data masking tool?

  • A single audit trail with comprehensive logs and reports helps you track whether data privacy regulations are being followed.
  • You can simulate masking rules before deploying them.
  • You can apply masking techniques to data regardless of its source or format.
  • The software is compliant with privacy regulations from GDPR, CCPA, HIPAA, PCI DSS, and GLBA.
