Both the contents of the files and the metadata, such as the names of your files and folders, are end-to-end encrypted. All the sophisticated encryption takes place automatically. Sharing encrypted files in Proton Drive is similar to sending them on many other platforms. Once uploaded, it’s simple to send encrypted files to anyone using a password-protected sharing link. Every file is encrypted on your device using your private key before being uploaded to servers in Switzerland, where user accounts are protected by strong privacy laws. As mentioned, most major cloud storage platforms are not end-to-end encrypted. The only negative aspect of most cloud storage providers is security. Many email services also offer cloud storage for this reason. Sharing files via cloud storageįor sharing large files or folders, people usually turn to a cloud storage provider. Proton Mail protects attachments with end-to-end encryption, but there’s still a limit on the size of your files. Most email providers don’t use end-to-end encryption, meaning they can access your files. Both Gmail and Proton Mail cap attachments at 25 MB. You can deliver the file directly to the person you’re sending it to.Ĭons: But all email providers have file size limits on their attachments. Pros: The biggest benefit is convenience. Probably the most common way to send files is by email. There are pros and cons of each choice: Sharing files via email attachment encrypting files onto a USB drive) to file transfer protocol (mostly used by developers).įor most people, the simplest way to send files is by email attachment or cloud storage. There are many ways to send encrypted files (new window), ranging from removable storage (e.g. Not even the service provider has a key to unlock the file.Ĭhoosing an encrypted file-sharing method The most secure form of cloud encryption is called end-to-end encryption, which ensures only you and the person you share a file with can access it. And most platforms keep a key for themselves, including Google, Microsoft, Dropbox, Box, and others. But different online service providers have different methods of storing those keys. Encryption is a way of locking files so that only people with the correct key can open them. Most data on the internet is stored and transmitted using some form of encryption. In the next section, we’ll describe a better way to send files over the internet: encrypted file sharing. The good news about that is users can greatly improve the security of their file sharing by using services that focus greatly on account security. Hackers’ best weapon is stealing passwords - The same IBM study found that compromised credentials remain the most popular attack vector for hackers.Using unencrypted methods to send sensitive information is a major red flag. One of the most common ways scammers obtained people’s personal data was by enticing them to share it by phone, email, or text message. Identity theft is common - One study (new window) found that identity fraud scams cost 42 million Americans $52 billion in 2021.This risk can be mitigated by using end-to-end encrypted cloud services and two-factor authentication. In other words, documents stored on internet-connected servers were able to be decrypted and stolen. Nearly half of data breaches happen in the cloud - Research by IBM (new window) determined that 45% of data breaches affected files stored in the cloud.Here are some of the risks involved with file sharing using unsecure methods: Globally, the average cost of each data breach is $4.35 million.Īnd yet most people still rely on services that don’t use end-to-end encryption to send files, such as Google products, Dropbox, WeTransfer, and others. If you consider the risks of unsecure file sharing alongside the ease of using encryption, it’s obvious that everyone should be using strong encryption to share data on the internet. Why secure file sharing matters What is encrypted file sharing Choosing an encrypted file-sharing method How to send encrypted files Sharing passwords for encrypted files Why secure file sharing matters This article explains what’s broken about most file-sharing systems and how you can start sharing encrypted files more securely, whether in your personal life or for your business. And yet data breaches still frequently spill sensitive files into the hands of hackers, and identity theft is a multi-billion-dollar industry.
