M&A deals involve exchanging thousands of confidential files, such as financials, contracts, IP, and more, among buyers, sellers, advisors, and regulators. VDR requirements include absolute confidentiality, strict access control and auditability so that each party can review data without risk of leaks. For example, centralized audit trails in a VDR ensure every document view is logged, giving full transparency to deal teams. This leads to "faster due diligence, reduced risk of data leaks, and simplified compliance".
