## And against it

- "Using Faker / Mimesis / dbt-style generation to "mask" an existing production copy will create new synthetic rows rather than transforming the real values in place" (Muse Glimmer 30B, Data masking)
- "There are many Python/Node.js libraries designed for basic masking (e.g., `faker` libraries). ... Use these only for local sandbox development, never for staging/prod environments involving PII" (Qwen 3.7 Flash, Data masking)
- "open-source tools like Faker, mcrypt, or basic scripting solutions exist, they often: Lack enterprise-grade audit logging" (MiniMax M2.5, Data masking)
