Why should I sanitize my logs?

Logs often contain sensitive data like user emails, session IDs, and internal server paths. Sharing raw logs can lead to security vulnerabilities or data breaches.

Is my log data stored?

No, the sanitization process is performed entirely in your browser using JavaScript. We do not store, upload, or have any access to your log data.

What types of data can it redact?

By default, it redacts IP addresses, emails, MAC addresses, and common sensitive patterns. You can also add custom keywords for redaction.

Does it work with large log files?

Yes, the tool is optimized to process large text blocks efficiently within the browser's memory limits.

Can I customize the replacement text?

Yes, you can choose to replace sensitive data with generic placeholders like '[REDACTED]' or '***'.

The Importance of Log Privacy

Sanitizing logs is a critical step in maintaining security compliance (like GDPR, HIPAA, or SOC2). Whether you are sending logs to a developer for debugging or uploading them to a public forum, ensuring that no sensitive infrastructure details or user data is leaked is paramount to protecting your systems and your users.
