A data room is a secure storage space for storing sensitive information. Data rooms are used to facilitate various transactions, including mergers and purchases, fundraising, first publicly traded offerings (IPOs) as well as legal proceedings. Traditionally, companies would send documents via email and spreadsheets, which is unsafe and inefficient for sensitive information since it is easy to lose track of different versions of documents and who has access to what information. Data rooms offer a central location for sharing documents with multiple parties simultaneously and provide advanced security options such as redaction, fence views and activity monitoring.

Once you’ve set up your dataroom, you will need to upload the data and then organize it into folders that reflect the transaction. Label documents and folders clearly so that stakeholders can find what they are searching for. Consider adding metadata to your documents so they can be searched and categorized. This will reduce the time needed to review documents and increase transparency and accountability in the event that there are issues with the document’s content.
