ARX Data Anonymization Tool vs DATPROF

ARX Data Anonymization Tool is open-source software for anonymizing sensitive personal data and examining privacy risk and data utility. Its graphical application supports data import and cleansing, transformation-rule setup, tailoring anonymized datasets, and analysis of utility and residual re-identification risk. It imports CSV, MS Excel, and relational database data, including MS SQL, DB2, MySQL, and PostgreSQL. Listed methods include k-anonymity, l-diversity, t-closeness, δ-presence, risk-based criteria, and semantic models such as differential privacy. ARX exports displayed tables to CSV and compares input with transformed data using information-loss models, descriptive statistics, and application-specific analyses. Its risk analysis reports prosecutor, journalist, and marketer attack risks, estimates population uniqueness, and can identify HIPAA Safe Harbor identifiers and further quasi-identifiers. A Java library and API can add anonymization capabilities to Java programs. The tool is free under Apache License 2.0 and supports Linux, macOS, Windows, API, and self-hosted options. The maker provides PGP/GPG-signed checksums for download integrity and states the software is provided without warranties or conditions.

DATPROF is a test data management platform for creating, protecting, automating and delivering data for development, testing and QA. Its modules cover privacy, subsetting, runtime, analysis and virtualization. Privacy masks test data and creates synthetic data while retaining representative characteristics, with more than 50 built-in generators supporting different languages. Subset extracts selected production data for test environments while preserving relationships. Runtime supports self-service provisioning, scheduling, monitoring and REST API automation. DATPROF can be deployed on premise or in the cloud, and says data stays in its database domains during masking. Native database support includes Oracle, Microsoft SQL Server, DB2 iSeries, DB2 LUW, PostgreSQL, EDB, MySQL and MariaDB. Supported flat file formats include CSV, Fixed Length, Recursive Fixed Length and XML. DATPROF says its masking can support GDPR, PCI and HIPAA requirements. Its security program aligns with ISO 27001 principles and includes SAST, dependency scanning and DAST in development. Support is available through a service desk portal, email and a documentation knowledge base. Pricing is available on request, and a free trial is listed.
