VDR stands for Virtual Data Room. It’s an online repository of documents and information used for secure sharing and collaboration during due diligence processes, such as mergers and acquisitions, IPOs, or audits. VDRs allow authorized users to access, view, and sometimes edit documents remotely while maintaining strict security measures to protect sensitive information. They often include features like document encryption, user permissions, activity tracking, and Q&A sections for efficient communication among stakeholders.
