Microsoft Presidio is an open-source tool for detecting, anonymizing, and protecting sensitive data. The TTY interface lets you use it directly in the CLI, fast and scriptable. This is not an API endpoint hidden behind layers—here, it responds to stdin and writes to stdout. That means you can pipe text straight into Presidio, process it on the fly, and integrate it into shell scripts without touching a browser.
Presidio TTY supports Named Entity Recognition (NER) for PII detection. It can find names, credit card numbers, phone numbers, email addresses, and more. It also lets you specify custom recognizers to catch proprietary data formats. You can choose between masking, redacting, or replacing sensitive tokens in a structured way. The CLI arguments give you control over model configuration, output format, and batch processing.
Integration is straightforward. Install Microsoft Presidio CLI tools. Launch the TTY mode. Feed text into it through pipes or redirects. It consumes plain text or JSON and returns sanitized data with minimal latency. This fits well in CI/CD pipelines, data preprocessing jobs, and immediate compliance checks. Because it’s open-source, you can inspect and modify the code to align with internal policies or regulatory requirements.
