How to securely share large documents outside your company

Organizations often invest heavily in regulating the exposure of sensitive information. This includes training employees as well as investing in tools that help protect and facilitate transferring sensitive documents outside the company.

Maintaining these safeguards becomes challenging when employees belonging to a different company are involved. Often such collaboration results in using free file-sharing services available on the Internet. Additionally, it is almost impossible to keep an oversight This when employees resort to using third-party file-sharing services to transfer confidential and sensitive documents.

Such scenarios play out almost every day in the corporate world, which raises an important question: how to facilitate and encourage secure file sharing with users outside your organization?


It is prevalent for humans to choose the shortest path to any solution. When the problem is sharing files, employees will naturally select a solution that is easily accessible, is not technically challenging, and requires the least effort.

The lack of a standardized solution will result in employees using their preferred/known method, compromising the privacy requirement for sensitive documents. Therefore, you need a secure file-sharing solution that can meet the privacy requirements and is easy to use and adapt to different use cases. In addition, this solution should not interfere with the employee's standard workflow.

On-Premise vs Public Service

When using a public services, such DropBox, Google Drive, OneDrive, your private files first go to a third-party service provider before reaching the final destination. When using such services there is no way to ensure the physical location of the servers that retain you files.
