How to share password protected files: 6 easy solutions to a delicate issue

Are you self-aware when you send docs to your colleagues? Here are 6 simple solutions on how to share password protected files and reach peace of mind.

Sharing password protected files is progressively becoming a delicate issue. We are living in an alienated, yet digitally connected world, where we are gradually being absorbed by the fast pace of innovation. We have arrived to the point of crossing the chasm between acting mechanically and rationally, this means that we send images, music and files to our peers, without consciously being there. Most of the time nothing happens, but one day we wake up and we suddenly discover that a third-party has accessed our private documents. If we think now that 36,000,000,000 is the number of exposed records worldwide in 2020, while €3.16 million is the average cost of a data breach to a company, this has already become a tremendous risk to bear.

We are at a point where an addictive habit, the one of quickly sending common files digitally, has contaminated our rationality and awareness to share sensible documents.

Here two questions arise abruptly from our minds:
Is our personal data really protected? Can we share password protected files without incurring an unexpected event?

If you ever asked yourself these questions you are in the right place! On this page, you’ll find:

  • The pros and cons of the 9 best solutions when it comes to sharing password protected files.
  • How Cubbit Private Links can be a 100% secure file transfer and an easy to use solution that you should try for free today.

If you are bothered by these (not very flexible) solutions to sharing password protected files, Cubbit Private Links are just what you are searching for.

How does it work? For every file stored you get 3 layers of security:

  1. Each file is encrypted with military grade protocol (AES 256 Key).
  2. It is split into chunks, that are multiplied to get redundancy and continuous uptime.
  3. All these chunks are spread across Cubbit’s Zero Knowledge Network

A network where nobody, not even the provider, can access your files! This guarantees you all the peace of mind you need.

For each encrypted file, an encryption key is associated. You don’t have to do anything, just park it on the cloud and share!
