Local-first tool that detects and pseudonymises infrastructure-specific secrets, internal IPs, MACs, cloud keys, tokens, connection strings, that generic PII tools aren't built to catch. General DLP tools are built for customer data; security practitioners leak a different class of identifier entirely, and Scrub is built specifically for that gap.
- ~30+ entity types via a custom Presidio recogniser pack
- FastAPI service, Next.js review UI, pipeable CLI, git pre-commit hook, and a CI workflow that gates on audit results
- Consistent, reversible pseudonymisation: same input always maps to the same output, so sanitised data stays analytically useful
- OCR redaction for images and screenshots planned
