The Problem
Modern applications generate JSON and XML logs containing customer identifiers, email addresses, IP addresses, and user-agent strings. These logs are routinely shipped to observability platforms (Elastic, Datadog, Splunk) and analytics warehouses. A Sonra.io engineering blog post specifically documents the challenge of "masking, anonymizing, and obfuscating PII in XML and JSON data" as one of the most common data engineering problems. The GDPR Article 5(1)(e) storage limitation principle requires that personal data be deleted or anonymized when no longer needed — but log retention policies often keep JSON logs for months or years, creating a silent GDPR violation in every organization's observability stack.

How privacyhub.legal Addresses This
JSON and XML processing handles nested structure natively — PII detection operates on string values within the document model, not on the raw file bytes. Processing preserves document structure, only modifying PII-containing string values. Batch processing integrates into log rotation pipelines.
