Data security is more paramount than ever, and corporations have been scrambling to secure precious data against cyber attacks. One of the best data security practices is data masking—a process of scrambling or obscuring true data in a way which won’t make it unusable. For testing, for analytics, for regulatory purposes, corporations have airtight data masking solutions in place in an effort to stave off data leaks and security nightmares.
If you’re looking for the best tools in 2025, you’re in the right place. Let’s go over some of the top data masking solutions that are making waves this year.
1. K2View Data Masking
If your organization is in need of a scalable, high-speed solution, think about using K2View Data Masking. This solution is ideal for large enterprises processing large amounts of sensitive data and needing it protected in real-time, all without a loss of speed. It is particularly preferred in banking, healthcare, and telecom companies, wherein data security and regulatory obligations take priority.
A distinguishing characteristic of K2View is its micro-database structure. Instead of masking entire databases in a batch operation, which is time and resource-intensive, it separates data into smaller, individual micro-databases, each for an individual customer or business entity. This improves masking efficiency and makes it faster, especially in real-time environments.
Dynamic data masking for live databases is also offered by K2View, so unauthorized users see a masked data view, and authorized users see actual data. It is completely able to support cloud, on-premise, and hybrid environments, so it is a highly flexible solution for businesses which have complex IT environments.
A further significant advantage is its support for data tokenization—a process which replaces data with non-sensitive tokens. This gives a further security layer, so in case an unauthorized person succeeds in accessing data, they won’t be able to interpret it.
A solution oriented for speed, scale, and real-time security, K2View is a perfect tool for enterprises that want best-in-class data security without compromising on performance.
2. IBM InfoSphere Optim
IBM InfoSphere Optim is another big player in data masking. This is especially valuable for large dataset-holding organizations. In addition to masking data, it assists in data archiving and subsetting, so you can process smaller, easier-to-handle data chunks without compromising on security.
Its uniqueness is its ability to support unstructured data along with structured data. Be it traditional databases or modern-age cloud storage, it is all taken care of. Secondly, it provides inbuilt compliance, which is a lifesaver for businesses trying to comply with regulations like GDPR and HIPAA.
3. Delphix Data Masking
If your business is driven by a priority for speed, a great solution is Delphix Data Masking. This solution is ideal for businesses who have a pressing need for quickly masking data, for example, test and development environments. Testers and developers can make use of masked data which is just as similar as live data—but which isn’t a security risk.
Its strongest point is its automation masking, which avoids human mistakes. With it enabled, it constantly monitors and protects sensitive information in different databases and apps. Capable of supporting on-premise as well as cloud environments, it is an ideal solution for businesses utilizing hybrid environments.
4. Oracle Data Masking and Subsetting
Oracle is a major player in its industry, so it is not surprising it offers one of the best data masking solutions. Oracle Data Masking and Subsetting is for enterprises using Oracle databases, so it protects data when it is being shared between teams or exported for test environments.
The tool is perfect for data discovery automation, in which it can scan for databases and automatically detect data which must be masked. The tool is capable of supporting various masking formats so businesses can have a say in how data is masked.
An additional major benefit is it directly integrates into Oracle’s security platform, so it is an ideal solution for businesses currently utilizing Oracle solutions.
5. Mentis Data Masking
If regulatory compliance is your goal, Mentis Data Masking is a prime candidate. The solution is crafted for businesses so they can meet regulatory requirements of CCPA, PCI-DSS, and HIPAA in a secure process.
Its data discovery, which is based on AI, is what makes Mentis stand out. While it employs set rules for identifying sensitive data, it can learn and adapt, making it a more effective tool for identifying data it must protect.
Dynamic masking is another excellent capability, which enables businesses to apply data masking in real-time without making changes in the underlying database. This enables different users to have different views of data based on different levels of access.
6. Datagu
For businesses using both unstructured and structured data, Dataguise is a tool worth investigating. Dataguise is able to mask data in email, in databases, and in documents such as spreadsheets and PDF.
Its strongest asset is its context-aware masking. Instead of scrambling all data randomly, it reads the context in an effort to determine just how best to mask each piece of data. For example, it can mask just the last four digits of a credit card number, leaving visible the first part, which is a help for customer support teams.
It is also coupled with large public cloud environments of AWS, Azure, and Google Cloud, making it a perfect solution for multi-cloud enterprises.
7. Protegrity Data Protection Platform
If your organization is in a situation in which a solution beyond masking is needed, think about using Protegrity Data Protection Platform. The solution encompasses a combination of data masking, tokenization, and data encryption, which gives businesses a multi-layer defense.
A great example of this is policy-based security, which enables businesses to automatically create policy-driven rules enforcing data security on a wide set of scenarios. This makes security easier for large businesses with different departments.
Protegrity is all about performance as well, assuring data masking won’t slow down apps and databases.
This is a big benefit for businesses relying on business intelligence in real-time and on quick data processing.
Final Comments
Organizations can’t afford to overlook data security in a time of rising cyber threats. The right data masking solution can protect data, support compliance, and make it easier for teams to work safely with data.
If you’re looking for something real-time and dynamic, your best choices are Mentis or K2view. If your data is big, IBM InfoSphere Optim or Oracle Data Masking and Subsetting is a great idea. If multi-level security is your first priority, consider taking a hard look at Protegrity Data Protection Platform.
Ultimately, your best tool is a matter of your business needs. Whether your business is a startup, or a big business, whatever your size, making an appropriate decision now can protect you in a big way in the future.
