Mask your MySQL data with DOT Anonymizer

MySQL is one of the most widely used database systems for web, e-commerce, analytics, and SaaS applications.

Downstream environments (development, QA, pre-production, training) often replicate production data — exposing personal information (names, emails, addresses, IBANs, etc.) for purposes that are not strictly necessary.

In today’s context, where data protection is a top priority (GDPR, national data protection laws, internal compliance requirements), MySQL data anonymization has become a key control measure:

• Reduce breach risk: limit the impact of incidents on environments less secure than production.
• Compliance and governance: meet audit requirements, internal policies, and data minimization obligations.
• Realistic test data: preserve formats and data consistency for reliable testing.
• Industrialization: continuously feed your CI/CD pipelines with compliant data sets.

In short: less risk, more quality for your engineering teams.

DOT Anonymizer delivers a complete MySQL data-masking toolkit, covering detection, transformation, and control:

• Ready-to-use and customizable anonymization rules: emails, phone numbers, credit cards, IBANs, national IDs, names, postal addresses, and more.
• Preserved formats and distributions: so your applications behave just like in production.
• Cross-table and cross-database consistency: the same source value always produces the same anonymized value wherever it appears (primary/foreign keys, reference tables, duplicates).
• Repeatability and traceability: replay the same anonymization strategy with identical guarantees, and export your anonymization plans.
• Multi-DBMS support: if your information system goes beyond MySQL, align your anonymization practices across all your databases.

Key benefit: anonymized yet usable data — for reliable functional testing and reproducible analytics.

Before anonymizing, you need to know where the PII is. The discovery phase identifies the columns and tables containing personal or confidential data. The result: an actionable data map with priorities to guide your strategy. With DOT Anonymizer Data Discovery, automatically detect PII across your MySQL schemas.

Based on this mapping, you configure your rules: pseudonymization or irreversible anonymization, partial masking (e.g., emails), realistic replacement (names, addresses), generation of controlled synthetic data, and hashing/irreversibility for identifiers. Rules are enforced while respecting integrity constraints.

Handled by DOT Anonymizer:

• Foreign keys: keep links between tables consistent (customer ↔ orders ↔ payments).
• Intentional duplicates: ensure the same entries in CRM and ERP remain aligned.
• Application-specific formats: preserve structures like user.name@domain.tld or +33XXXXXXXXX.
• Performance: batch processing.

Once the rules are applied, DOT Anonymizer provides post-processing checks and detailed execution reports. You can then industrialize the process — integrate anonymization into your CI/CD pipelines or schedule regular environment refreshes.

• CI/CD & DevOps: add an anonymization job to your pipelines (after importing a production dump, before deploying to QA).
• MySQL dump anonymization: ideal for quickly refreshing environments while removing PII.
• In-database or extract-based anonymization: choose the method that fits your constraints (maintenance windows, data volumes, replication strategies).
• Data sharing & sandboxing: provide compliant datasets to partners, vendors, or data scientists — or to create secure internal sandboxes.
• Training & support: deliver realistic scenarios for support teams and training sessions, without exposing real data.
