By leveraging techniques such as tokenization and data masking, Informatica helps organizations with data de-identification while maintaining its integrity. Their cloud-based approach provides scalability and flexibility, making it easier for businesses to implement data anonymization measures. 

4. Oracle 

Oracle Data Safe is a cloud-based data security platform that offers a suite of features, including data anonymization capabilities. It enables organizations to mask sensitive information by applying techniques such as encryption, data shuffling, and substitution. Oracle Data Safe provides comprehensive auditing and monitoring tools to ensure data privacy compliance, making it an ideal choice for businesses powered by Oracle data stores. 

5. Statice 

Statice is an emerging data anonymization startup that specializes in synthetic data generation. Their innovative technology enables organizations to conduct realistic and privacy-preserving synthetic data generation that retain the statistical properties of original data. By leveraging advanced machine learning algorithms, Statice offers an efficient and secure way to share data while protecting privacy. Their solution helps organizations comply with regulations like GDPR. 

Data anonymization defined 

The anonymization of data refers to the act of hiding or removing Personally Identifiable Information (PII) from a dataset to safeguard the privacy of the individuals connected to that data. With anonymized data, it becomes extremely difficult, if not impossible, to identify or link individuals to their specific information. However, the data remains usable for testing, analysis, research, and other legitimate purposes. Data anonymization techniques include data masking, pseudonymization, data aggregation, randomization, generalization, and swapping. 

Benefits of 3rd-party data anonymization tools 

Partnering with data anonymization companies has its advantages: 

1. Complying with data privacy regulations 

   Enterprises handle vast amounts of PII from their customers, vendors, employees, and partners. To comply with data privacy regulations such as Europe’s General Data Protection Regulation (GDPR) and the California Privacy Rights Act (CPRA), enterprises need to ensure that sensitive data is properly anonymized and protected. 

2. Minimizing the risk of data breaches 

   Data breaches can have severe financial and reputational repercussions for enterprises. Through proper data anonymization, the risk of exposing sensitive information during data breaches is dramatically reduced. The right data anonymization tools can help companies protect against unauthorized access. 

3. Facilitating data sharing and collaboration 

   Organizations often need to share data with external parties, such as business partners or researchers. However, sharing raw data carries significant privacy risks. Data anonymization enables enterprises to share aggregated or de-identified data without revealing sensitive information, fostering collaboration while maintaining privacy. 

4. Supporting data-driven decision-making 

   Data anonymization allows enterprises to leverage data for analytics, machine learning, and other data-driven initiatives while preserving privacy. By removing personally identifiable elements, companies can perform analysis and extract valuable insights from anonymized data without compromising on privacy. 

5. Building customer trust 

   In an era where privacy concerns are on the forefront of users’ minds, enterprises need to prioritize customer trust. Enterprises who take data anonymization seriously demonstrate their commitment to protecting customer data and respecting privacy rights, which can, in turn, enhance customer trust, loyalty, and overall brand reputation. 

Choosing data anonymization companies and tools  

Choosing the right company 

In today's data-driven world, organizations collect vast amounts of data. However, the misuse of, or unauthorized access to, this data can pose significant risks. By transforming personal or sensitive data so that it can’t be linked to a specific individual, data anonymization reduces the risk of re-identification and is an essential component of any data protection strategy. Data anonymization tools allow businesses to continue to collect and use data for development, testing, and analytics, while also complying with data privacy laws.  

With so many companies offering data anonymization services, it can be challenging to identify the most suitable option, especially for enterprises with complex data environments. In this article, we’ll overview why data anonymization matters, and why choosing the right vendor is so important. We’ll also briefly describe the top 5 data anonymization companies you should consider when choosing a partner. 

Choosing the right tools 

Identify your top data anonymization requirements before speaking with vendors. For example, make sure the tools can:  

• Anonymize data from a variety of structured and unstructured data sources
• Discover sensitive data (PII/PHI) in those data sources
• Pipeline anonymized data from one environment to another
• Transform the data in other ways/formats
• Obfuscate data using out-of-the-box techniques

The business entity approach to data anonymization

Data anonymization tools play a critical role in helping organizations effectively navigate privacy regulations and securely share data. When choosing the right data anonymization company to partner with, look for vendors that take a business entity approach.

Entity-based data masking is the most effective and advanced way to anonymize data. It manages and stores all the data associated with specific business entities, such as customers, in individually protected Micro-Databases™. With this technology, data teams can securely anonymize data inflight using a variety of techniques, including dynamic data masking, data tokenization, and synthetic data generation.
