In mergers and acquisitions (M&A), data rooms are essential for securely managing confidential documents. 

Though traditionally, physical data rooms were the standard for secure document sharing, virtual data rooms (VDRs) now outpace traditional solutions. No wonder the global virtual data room market was valued at $2.37 billion in 2023 and is expected to expand to $13.22 billion by 2032.

This article comprehensively compares physical data rooms and virtual data room solutions to help M&A professionals, legal teams, financial advisors, and corporate managers make informed decisions about their data storage options.

What is a physical data room?

Physical data rooms are secure, controlled spaces where paper documents are stored, accessed, and reviewed under strict supervision. Commonly used in high-stakes business proceedings like legal and financial transactions, a traditional data room ensures data security by storing confidential information in a well-protected physical space.

Key characteristics of secure physical data rooms

  • Controlled access: Document reviews are conducted on-site, requiring scheduled visits for teams to gain access to the physical space. This controlled access allows direct supervision but slows down the document review process, especially for teams located outside of the immediate area.
  • Higher operational costs: Travel, rental fees, and security personnel expenses add up, making physical data rooms a more expensive option for storing privileged data.
  • Physical security measures: Traditional physical data rooms rely on physical security measures like “no-electronics” rules to prevent unauthorized recording. However, without digital audit trails, tracking specific documents and user access details is limited.

Physical data rooms are valuable for storing data that requires stringent, in-person control. However, they introduce logistical challenges, especially for multi-location or cross-border transactions.

This is why virtual data room providers are gaining traction. They present more flexibility, accessibility, and ease of use while offering a higher level of document protection.

What is a virtual data room?

Virtual data rooms are internet-based data rooms that provide global, remote access to confidential documents in a secure online environment. A VDR ensures an advanced level of sensitive data protection thanks to multi-layered data encryption, restricted access to sensitive files, and a safe data backup in case of emergency. 

Compared to traditional data rooms, VDRs provide a more scalable solution, as they allow instant data sharing in cross-border transactions, with only a secure internet connection required instead of a physical presence. However, VDRs offer even more benefits.

Key characteristics of virtual data rooms

  • Global accessibility: Virtual data rooms allow authorized individuals to access documents from anywhere with an internet connection, making it easy for multi-location teams to complete the due diligence process efficiently. This remote access accelerates decision-making in sensitive legal transactions.
  • Document management flexibility: Virtual data rooms provide features like custom views, advanced search capabilities, and collaboration tools. They also support secure document storage with advanced encryption and granular access controls to ensure that only authorized individuals can view highly confidential documents.
  • Real-time updates and alerts: Notifications keep teams informed when documents are added or updated, supporting immediate actions during the due diligence or document review process.

Virtual data rooms provide flexibility and reduce logistical barriers, allowing for secure online document sharing and data storage that adapts to modern transaction needs.

Key differences between physical and virtual data rooms

Here’s an expanded look at key differences in accessibility, security, and cost considerations between physical and virtual data rooms for M&A transactions.

Accessibility and convenience

Accessibility is a key differentiator for VDRs compared to physical data rooms, affecting the efficiency of the due diligence process.

Accessibility in virtual data rooms

  1. 24/7/365 global access: Virtual data rooms enable remote access anytime, eliminating the need for physical travel and facilitating faster due diligence.
  2. Cross-platform compatibility: Users can access VDRs on mobile devices, desktops, or tablets, with automatic format conversion to ensure compatibility.
  3. Concurrent access for multiple users: Hundreds of users can access a VDR simultaneously with no geographical or time-zone limitations.
  4. Real-time collaboration: Virtual data rooms offer collaboration features, such as comment threads and real-time updates, which streamline discussions and decisions.

Accessibility in physical data rooms

  1. Business hour limitations: Access is limited to business hours unless special arrangements are made, often resulting in scheduling conflicts.
  2. Geographical and logistical constraints: Users must travel to the physical location, introducing costs, time-zone issues, and transportation dependencies.
  3. One group at a time: Physical rooms typically support one group at a time, making concurrent reviews challenging.
  4. Weather and accessibility: Physical access may be hindered by Transportation issues, weather, and space limitations may hinder physical access, restricting flexibility.

As is evident, virtual data rooms provide 24/7 global access without scheduling conflicts, enabling multiple users to collaborate efficiently from anywhere in the world as compared to physical data rooms.

Security

Security is crucial for both physical and virtual data rooms. While both protect sensitive information efficiently, the intricacies of their approach differ.

Security in online data rooms

  1. Military-grade encryption: Virtual data rooms utilize high-grade encryption (AES-256 SSL/TLS) for data in transit and at rest to ensure data integrity and avoid data breaches.
  2. Watermarking: Documents can be watermarked with identifying information, deterring unauthorized sharing and tracking document origins.
  3. Multi-factor authentication (MFA): Multi-factor authentication options, such as biometrics, SMS codes, and hardware tokens, add a layer of protection beyond standard passwords.
  4. IP restrictions and automated timeout: Virtual data room admins can restrict user access to specific IP addresses and automatically log out inactive users for enhanced security.
  5. Document-level permissions: Virtual data rooms allow for granular access controls, enabling administrators to control document access by role (e.g., view-only, print, download, or edit).
  6. Comprehensive audit trails: Digital audit trails track every VDR action, including who accessed what, when, and for how long.
  7. Anti-virus and download restrictions: Virtual data rooms scan uploads for viruses and prevent downloads/printing through browser restrictions, reducing potential security risks and eliminating human error.

Security in physical data rooms

  1. Physical security measures: Physical data rooms implement multiple security layers such as keycards, sign-in/sign-out, and security personnel to monitor access.
  2. Clean room policies: Devices like phones and cameras are restricted within physical data rooms, reducing the risk of data leaks but also limiting productivity.
  3. In-person oversight: Access to sensitive documents is supervised, but there are no digital audit trails to track document access details comprehensively.
  4. Secure document storage: Sensitive information is stored in fireproof safes during off-hours, providing additional protection.

For high-stakes M&A transactions, virtual data rooms offer robust security features that are traceable, automated, and more effective for comprehensive monitoring.

Costs and maintenance

The pricing factor is yet another consideration businesses should take into account when choosing between a physical and virtual data room. While pricing differs from one provider to another, the cost structure in these solutions is pretty straightforward.
