Redax

Permanently Remove Sensitive Information from PDF Files

Keep Sensitive and Private Information in Your PDF Files Protected from Unwanted Exposure

If you manage classified, sensitive, or private information day in and day out, you know firsthand that you need a secure and thorough redaction process that easily, consistently, and securely removes sensitive text and graphics. Failures to redact can have costly and dangerous consequences not only for organizations but also for the people whose privacy or security they are protecting.

Thousands of Federal, State, and Local government agencies, as well as law firms, corporations, and health organizations rely on Appligent’s Redax plug-in for Adobe® Acrobat® every day to give the ultimate protection for sensitive information.

Appligent was the first to natively redact PDF documents and holds U.S. Patent No. 7,428,701 on the “method, system and computer program for redaction of material from documents.”

Information removed from PDF files using Redax cannot be recovered. 

If you need automated, document redaction processes on a server—for example to apply redaction criteria to a large number of documents—learn more about Appligent’s Redax Enterprise Server.
