Vault, by Cloak, is the easiest to use, file sharing app with document rights management. You can also sign PDF files securely.

Our product is based on advanced public key encryption service that removes the need to share file passwords or encryption keys.

Moreover, it works across major platforms: Windows, MacOS X, Linux, Android and iOS devices. Access your protected files anywhere, anytime!

Security features include:

1. Digital rights management. Share text / markdown, pdf and images with read-only access to specific recipients. Documents and folders can be shared to individual users or hierarchical user groups, with fine-grained access rights.

2. Client-end encryption. Vault uses public key encryption. The data is never encrypted or unencrypted solely in the cloud; it is always done on the user's device.

3. Mobile endpoint control. Since each device is tied to a unique key, stolen device's file access can be easily revoked.

4. End-to-end document protection. Documents are protected throughout their life cycle, when they are at rest, in-transit or in-use.

5. Version control. Automatic versioning with options including locking, deletion and adding descriptions for individual version items.

6. Transfer of large files (over 1GB) is supported by splitting the data into smaller segments, which are independently encrypted. This allows recovery from network interruptions and automatic resumption of incomplete uploads and downloads.

7. Audit trails. Track your team’s usage using event logs, and know who read which documents at what time.

Vault is free to download and is not plagued by advertisements.
