Data room confidential mode is a feature which allows administrators of virtual data rooms to limit a specific user’s use of the VDR based on their IP address or device type. It’s a great tool for M&A transactions and other sensitive business ventures.

A good provider will allow users to customize their rights and two-factor authentication. They will also provide remote shred that deletes downloaded documents after administrators have removed access. Additionally they will be able to handle most common file formats including PDFs and XLSXs. The best providers can add watermarks on the files users download, which deters users from sharing copies of the files online. They can also set an expiration date for the files downloaded to prevent downloads that are not authorized.

Other useful tools include redaction that allows the administrator to erase (black out) fragments of text or certain areas of a document from the view of authorized users. This is essential because it protects all personal information and crucial business data from hackers. The most reliable VDR providers can modify PDF, Doc, Docx, Txt, PPT, PPTX, JPG, GIF, and Q&A files.

Some providers allow users to print out documents that will automatically include a “watermark” and download the original version. Additionally, a reputable provider provides users with a question and answer feature which helps them talk about files in the data room and record answers in a searchable database. This is a valuable tool for M&A transactions, or any due diligence project.
