How do you redact legal documents before sharing them?
You redact the names, contact details, dates and identifiers of the parties and third parties in each document, while keeping the facts needed for the analysis.
With NymData, installed on your own servers, you select the case folder.
Each document, in PDF or Word, is processed and a redacted copy is created, with an audit report.
The original documents stay at the firm.
