The most useful tool for cybersecurity is encryption. But for many, sharing encrypted documents and files isn't affordable or simple enough for everyday use. Well that's changed. 

If you want to share documents and files on the internet but need security, encryption is the key. Historically, sharing an encrypted document from end-to-end has been a clunky process requiring a paid software service. 

End-to-End Encryption

The ideal and most secure approach to sharing encrypted information is "end-to-end."

"End-to-end encryption is a system of communication where only the communicating users can read the messages. In principle, it prevents potential eavesdroppers – including telecom providers, Internet providers, and even the provider of the communication service – from being able to access the cryptographic keys needed to decrypt the conversation. Wikipedia.

Now there is an easy way to share documents and files with the security of end-to-end encryption, and it's from Mozilla, the nonprofit provider of great internet tools built for privacy and information security. The service is called Firefox Send, and it's free. 

End to End Encryption

NOTE - It's not a coincidence that the best browser for privacy and security is also brought to you by Mozilla. The Firefox browser is the best bet as your default for everyday use, and it is also free. More here

Firefox Send, by Mozilla

Firefox Send is a free encrypted file transfer service that allows users to safely and simply share files from any browser. 

Whether you're sending sensitive financial documents or a home video with friends, your files should be protected. That's where Firefox Send comes in. With Firefox Send, you can:

  • Share large files online with an encrypted link that "self-destructs"

  • Set the number of times your file can be downloaded

  • Choose when you'd like your link to expire

  • And when you're logged in, you can send up to 2.5GB


"Send uses end-to-end encryption to keep your data secure from the moment you share to the moment your file is opened. It also offers security controls that you can set. You can choose when your file link expires, the number of downloads, and whether to add an optional password for an extra layer of security."  Mozilla


It's a good idea to create an account with Firefox, if you have not already done so. Creating an account will give you access to more privacy and security features with all of Mozilla's internet products.

We recommend Mozilla's Firefox Send for everyday use and sharing sensitive documents and files on the internet. Now, end-to-end encryption is free. Find out more and try it for yourself, here:

*** Remember to use a great password for important accounts, like Firefox. And for best results and optimal security, we suggest using a password manager. Here is our top recommendation.
