End-to-end Encryption

Full life-cycle data encryption for total security assurance

Protection That Goes Above and Beyond.

Your data is encrypted from the minute it’s uploaded to the day it’s deleted - and beyond.

  • End-to-end encryption safeguards your data throughout its entire VDR journey, from upload to download
  • Documents remain encrypted in transit, shielding them from unauthorized access even if intercepted by hackers. 
  • You hold the encryption keys, ensuring only authorized users can access your confidential information. 
  • Even when viewed within the VDR, the underlying data stays encrypted for an extra layer of protection.
  • Downloaded documents remain encrypted on user devices, preventing unauthorized access even if compromised. 
  • End-to-end encryption strengthens audit trails and bolsters adherence to data privacy regulations. 

Why End-to-end Encryption

Use data room smart tools to make deals easier

Data Protection at Rest and In Transit

Files are encrypted both while stored in the cloud and during transmission between your device and the VDR. This ensures unauthorized access is impossible even if hackers intercept data during transfer.

Complete Encryption Key Control

bestCoffer uses a zero-knowledge encryption approach. This means that neither bestCoffer nor any third party has access to your encryption keys. Only authorized users with the correct decryption key can access your documents.

Secure Online Viewing

Even when users are viewing documents within the VDR platform, the underlying data remains encrypted. This adds an extra layer of security compared to traditional VDRs where documents might be decrypted for viewing.

Offline File Protection

With bestCoffer, even if a document is downloaded for offline access, it remains encrypted. This prevents unauthorized access to sensitive information, even if a user’s device is compromised.

Enhanced Audit Trails

End-to-end encryption strengthens audit trails within the VDR. Every file access and action is logged, but the encrypted data itself remains unreadable within the logs, providing an extra layer of security.

Compliance with Regulations

End-to-end encryption helps ensure your VDR adheres to strict data privacy regulations. This is essential for organizations working with sensitive information or operating in regions with stringent data protection laws.

How Full Life-cycle Encryption Works

End-to-end encryption (or E2EE) in file sharing, particularly within Virtual Data Rooms (VDRs) , provides a robust security layer for your sensitive documents throughout their entire lifecycle. 

These stages include: 

  • File Creation and Storage: Even before uploading to the VDR, E2EE can be applied on your local device using encryption software. This ensures the data is scrambled and unreadable by anyone without the decryption key. 
  • File Upload and Transmission: During upload to the VDR, the encrypted file remains protected. The data travels through the internet in a scrambled format, inaccessible, even if intercepted. 
  • File Storage Within the VDR: Once uploaded, the document remains on the VDR’s servers. But with E2EE, the data remains encrypted at rest, meaning it’s stored in an encrypted format. This protects it from authorized access within the VDR itself.
  • File Download and Viewing: Even when a user downloads a file for offline access, E2EE keeps the document encrypted, which prevents unauthorized viewing if a user’s device is compromised. 
  • Full Decryption and Access: Only authorized users with the decryption key can access the original, unencrypted content of the file. 


E2EE scrambles your files before they even enter the VDR, and they remain encrypted all the way to the recipient’s device. This ensures only authorized users with the decryption key can access the information, regardless of where it’s stored or transmitted. 


Traditional VDRs might encrypt data at rest (on servers) and in transit (during transfer). However, E2EE takes it a step further by keeping it encrypted even when viewed within the VDR platform. 

End-to-end encryption offers an extra layer of security, especially when dealing with highly sensitive documents. It protects information from unauthorized access even if the VDR provider itself experiences a breach in security. 

In most cases, it’s the data owner. This gives you complete control over who can access your information. 

It does add an extra processing step, but your VDR is optimized for speed. There shouldn’t be any significant delays in uploading or downloading or accessing your files.
