Tool usage guide
The Log Redactor is a utility tool that batch redacts sensitive data from log files using configurable rules and multiple redaction strategies. It helps protect privacy and ensure compliance with regulations like GDPR, HIPAA, and PCI DSS by automatically masking or replacing personal information.
Background
Web server logs contain user IP addresses and email addresses from visitor interactions.
Problem
Need to share logs with an analytics team without exposing personal data protected under GDPR.
How to use
Paste the log content, select the GDPR preset, and run the tool with dry run enabled to preview.
Outcome
IP addresses are masked as X.X.X.X and emails are replaced with [EMAIL], ensuring GDPR compliance.
Background
Application logs include patient medical record numbers and social security numbers.
Problem
Must redact sensitive health information before logs are reviewed by external auditors for HIPAA compliance.
How to use
Upload the log file, choose the HIPAA preset, and enable the generate report option.
Outcome
SSNs are redacted with only the last four digits visible, and medical terms are masked, meeting HIPAA standards.
Strategies include full replacement, masking characters, keeping first or last N characters, hashing, and partial display (e.g., j***@email.com).
Yes, you can define custom rules using regex patterns and specify the redaction strategy and replacement text.
Yes, enable the dry run feature to preview changes without modifying the original logs.
Yes, you can generate a report summarizing the redactions made for audit purposes.
Presets include GDPR (email, phone, IP, SSN), HIPAA (medical data plus PII), and PCI DSS (card numbers, security codes).
