    Top Data Masking Tools Comparison for 2025
    8:20

    Data masking replaces PII with fake but realistic data. Learn about the top tools for 2025: K2view, EPI-USE LABS, Oracle, IBM, Camouflage, and Informatica. 

    What are Data Masking Tools? 

    Data masking tools are software products that anonymize sensitive data, rendering any Personally Identifiable Information (PII) contained in the raw data indetectable. They’re generally considered to be the first line of defense in data protection because, if done right, re-identifying the data would be impossible.  

    Data masking tools help companies secure data in various industries, such as: 

    • Financial Services 

      PCI-DSS, the Payment Card Industry Data Security Standard, is an information security standard created to control cardholder data and reduce credit card fraud. 

    • Healthcare Services  

      PHI, Protected Health Information is any health status data, including the provision of, and payment for, healthcare services – that can be linked to a specific individual. 

    • Commerical Services 

      PII, Personally Identifiable Information, is any data that can be used to identify someone, including names, addresses, telephone numbers, and Social Security Numbers.

    The Need to Comply with Global Data Privacy Laws 

    Choosing the right data masking tool ensures you stay compliant with the growing range of international data protection regulations, including:  

    1. GDPR and DORA

      The EU’s General Data Protection Regulation of 2016 and Digital Operational Resilience Act (DORA) of 2024 spell out the obligations that companies must perform to endow individuals with control and rights over their personal information. DORA compliance is more focused on personal financial data stored by EU firms.

    2. CPRA 

      California’s Privacy Rights Act of 2020 extends its Consumer Privacy Act of 2018 specifying data protection obligations for businesses to carry out to provide privacy rights to consumers. Although spearheaded in California, many other US states have since followed suit. 

    3. HIPAA 

      The US Health Insurance Portability and Accountability Act of 1996 requires healthcare providers to protect sensitive patient health information from being disclosed without the patient’s consent or knowledge. 

    4. SOX 

      The Sarbanes-Oxley Act of 2002 is a US federal law that requires transparency and accountability in financial record keeping and reporting for corporations. 

    5. DCIA 

      Canada’s Digital Charter Implementation Act of 2020 provides individuals with control and rights over their personal information as first dictated by GDPR, and further focused by DORA European regulations

    6. APPI 

      Japan’s Act on the Protection of Personal Information of 2003 regulates the handling of personal information by individuals, government agencies, businesses, and non-profit organizations. 

    7. PDP 

      Indonesia’s Personal Data Protection Law of 2022 regulates the collection, use, disclosure of personal data by international organizations and governmental and private entities. 

    What to Look for in a Data Masking Tool 

    Consider investing in a future-ready data masking tool with full functionality, otherwise you may need to add additional point solutions to fill in the gaps. Make sure the data masking software you choose offers the following features and capabilities: 

    • Integration with any data source 

      Many data masking tools are only able to extract data from specific sources. For an enterprise with many different databases, it’s critical that the solution you choose can easily access – and automatically update – data from ALL sources, from legacy mainframe systems and SAP, to MongoDB and NoSQL databases. 

    • PII Discovery 

      Data comes in many different formats, which is why it’s important the tool you choose can automatically detect PII scattered all over the enterprise, and can map schema relationships.  

    • Dynamic data masking 

      An enterprise-grade data masking tool must be able to dynamically determine who can have access to real data, and to what extent. Dynamic data masking decreases the risk of internal security threats while still enabling individuals and teams to access data when they need it.  

    • Wide choice of data masking techniques 

      It’s critical to employ a software that has the ability to work with multiple data masking techniques, like anonymization, pseudonymization, redaction, shuffling, and more. This gives your platform team the flexibility to choose the one that best suits each use case. 

    • Ability to mask unstructured data 

      Unstructured data often contains PII, so unstructured data masking is imperative. This can be anything from images and PDFs to XML files and chats. It’s often difficult to detect PII when it’s in unstructured data, but it’s no less important since regulatory bodies do not differentiate between structured and unstructured. Your data masking tool must be able to detect and mask sensitive information in both structured and unstructured formats.
