A reputable provider will offer users to set their own rights in granular ways and two-factor authentication. They will also offer remote shred functions that deletes downloaded files after administrators have removed access. They will also be able handle the most widely used file formats that include PDFs and Excel XLSXs.

Redaction is a different tool that allows the administrator to block (black out) specific text fragments or regions of a file from authorized users. This is crucial because it will protect all personally identifiable information and crucial business data from hackers. The most reliable VDR providers can remove PDF, doc, documents, txt and ppt as well as pptx, pptx images, jpgs and gifs along with Q&A attachments.

Some providers allow users to print out documents that will automatically include a “watermark” and download the original version. Additionally, a reputable provider offers users a question and answer feature that lets them discuss files in the data room, and save answers in an easily searchable database. This is an excellent tool for M&A transactions or any other due diligence project.
