Walled Redact masks PII across 10+ modalities: text, images, documents (PDF, DOCX), code (50+ languages), and audio. It detects names, addresses, phone numbers, financial data, medical records, and custom entity types defined by your organization.
When Walled Redact masks data before sending it to an LLM, it preserves a secure mapping. When the LLM responds, Walled Redact automatically restores the original values in the output - so your employees see real names and data, but the LLM never had access to it.
Walled Redact achieves 98.2% PII detection accuracy across all supported modalities, with sub-30ms processing latency. This includes edge cases like handwritten text in images, embedded data in PDFs, and comments in source code.
