Redact sensitive information from documents — automatically, before delivery

Lido identifies personally identifiable information, account numbers, social security numbers, and other sensitive content across your documents and applies permanent redactions before the files are delivered, shared, or archived. No manual highlighting, no inconsistent coverage, no accidental exposures.

  • Consistent redaction at scale. Every instance of every sensitive field is redacted, not just the ones someone remembered to cover. The same rules apply to every document in the batch.
  • Configurable redaction rules. Define what to redact: SSNs, dates of birth, account numbers, patient names, medical record numbers, or any custom pattern. Different rules for different document types.
  • Permanent, not cosmetic. Lido applies permanent black-box redactions to the PDF. The underlying text is removed, not just visually hidden, so redacted content cannot be copied or uncovered.

How redact and deliver works in Lido

1

Ingest documents requiring redaction

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

2

Detect and redact sensitive content

Lido scans each document for PII patterns, custom-defined sensitive fields, and any content your rules specify. Detected content is permanently redacted, black boxes replace the underlying text, not just the visual appearance.

3

Deliver clean copies

Redacted files are named, logged, and delivered to the configured destination: shared drive, email, secure portal, or downstream system. An audit log records what was redacted and where.

Why manual redaction fails compliance and scale requirements

The highlight-and-hope approach

Someone opens a PDF in Acrobat, scrolls through page by page, manually highlights every SSN, account number, and patient name they can find, and applies redaction. A 40-page document takes 20 minutes. It is error-prone, reviewers miss instances, especially when the same data appears in tables, headers, and footers. Cosmetic redactions (black text over white background, or just the visual layer covered) are a compliance failure waiting to happen.

Automated redaction that never misses an instance

Define your redaction rules once. SSN pattern, account number format, patient name fields, custom identifiers. Lido scans every document, every page, every table, every header, and applies permanent redaction to every match. No missed instances. No cosmetic-only redactions. An audit log for every document processed.

Common use cases

Healthcare

HIPAA-compliant document sharing with redacted PHI

Patient records shared with third parties, researchers, or external reviewers need PHI removed before release. Lido redacts patient name, DOB, MRN, SSN, and other PHI identifiers permanently before delivery.

Legal

Redact PII from discovery documents before production

Discovery production requires PII redaction before documents are delivered to opposing counsel. Lido processes the entire production set, applying consistent redaction rules across thousands of documents, before any file leaves your control.

Financial Services

Redact account numbers before regulatory reporting

Documents submitted to regulators or shared with auditors must have account numbers, routing numbers, and taxpayer IDs redacted. Lido handles the redaction before any document is transmitted.

Government

Fulfill FOIA requests with automatic redaction

FOIA responses require exemption-based redaction before release. Lido applies rule-based redaction for personal privacy exemptions across every responsive document in the production batch.
