The Problem With Other PDF Tools
Non-Disclosure Agreements contain some of your most sensitive business information — trade secrets, client names, proprietary processes. The last thing you should do is upload that document to a random cloud server just to add a signature.
Why SignifyPDF Is the Safer Choice
NDAs are legally sensitive. Uploading them to a cloud PDF tool means that company has access to your confidential business terms. With SignifyPDF, your NDA is signed entirely in your browser — no file ever leaves your computer.
