Client-Side PII Data Scanner & Redaction Tool

The Client-Side PII Data Scanner & Redaction Tool allows software engineers, support agents, and security auditors to inspect and redact sensitive personal information from text data. Users can paste server logs, customer support tickets, error traces, or configuration files directly into the tool.

The scanner executes 100% locally within the web browser. It identifies email addresses, phone numbers, US Social Security Numbers (SSN), credit card numbers (Luhn validated), IPv4 addresses, and date of birth patterns, providing one-click automated redaction (e.g., replacing sensitive values with `[REDACTED_SSN]`) before sharing.

When developers and support engineers troubleshoot application bugs, they often need enough context to correlate log events without exposing raw personal identifiers. Full redaction replaces the value completely (e.g., `[REDACTED]`), which eliminates all privacy risk but can hinder debugging if an engineer needs to determine whether two log events refer to the same user.

High-assurance redaction engines support deterministic tokenization (or salted hashing). Under this approach, an email like `[email protected]` is transformed into `[USER_ID_7f8a9]`. Every occurrence of Alice’s email across the log file receives the identical token, allowing engineers to trace user transaction flows perfectly while ensuring the actual email address is never exposed.
