Learn About Log Redaction
What is Log Redaction?
Log redaction is the process of removing or masking sensitive information from log files before sharing, analysing, or storing them. It protects PII, credentials, and other confidential data from unauthorised access.
Why Redact Logs?
Logs often contain sensitive data that shouldn't be shared with third parties, stored long-term, or exposed in debugging sessions. Redaction helps meet compliance requirements (GDPR, HIPAA) and reduces data breach risk.
