Redact sensitive data from documents before delivery

Lido finds sensitive data in your documents and applies permanent redactions before delivery. SSNs, account numbers, PHI. Detected and removed automatically.

  • Pattern-based detection. SSNs, account numbers, DOBs, and custom patterns are identified across any document layout.
  • Permanent redaction. Sensitive data is replaced, not just covered. Redacted content cannot be recovered from the output.
  • Batch processing. Drop a folder and every document gets the same redaction rules applied before delivery.

How redact and deliver works in Lido

1

Ingest documents requiring redaction

Upload PDFs, connect a watched folder, or receive documents from email or shared drive. Lido queues each file for redaction automatically.

2

Detect and redact sensitive content

Lido scans each document for PII patterns and custom-defined sensitive fields. Detected content is permanently redacted—underlying text removed, not just visually covered.

3

Deliver clean copies

Redacted files are named, logged, and delivered to your destination—shared drive, email, secure portal, or downstream system. An audit log records every redaction.

Why manual redaction fails compliance and scale requirements

The highlight-and-hope approach

  • Someone scrolls through each PDF manually highlighting SSNs and account numbers.
  • A 40-page document takes 20 minutes and reviewers still miss instances in tables.
  • Cosmetic-only redactions leave sensitive data recoverable in the file layer.

Automated redaction that never misses an instance

  • Define redaction rules once—SSN patterns, account formats, custom identifiers.
  • Every page, table, and header is scanned so no instance is missed.
  • Permanent redaction removes data at the file level, not just visually.

Inconsistent redaction is a compliance risk. Automated redaction is not.

Set your redaction rules once and let Lido apply them consistently to every document, every time.
