Protect your files with end-to-end encryption. Keep your sensitive data safe from hackers, snooping governments and the dangers of internal breaches. Secure your files all the way from your computer to the people you share them with. With our end-to-end encryption, nothing leaves your device unencrypted. Only you have the keys to read the content of your files.

  • Proven AES256 end-to-end encryption – Using end-to-end encryption, Tresorit encrypts every file and relevant metadata on your devices with unique, randomly generated encryption keys. These keys are never sent to our servers in unencrypted format. Accessing files is only possible with a user’s unique private decryption key.
  • Swiss Privacy + EU data centers – Zero-knowledge authentication. Unlike other services, Tresorit never transmits or stores files, encryption keys and user passwords in unencrypted or unhashed form. Due to the strength of Tresorit’s end-to-end encryption and security, breaking this protection would take several human lifetimes. This is why we can never recover forgotten passwords, or hand over your data without your consent in case of a legal inquiry.
  • Hardened TLS – TLS (the successor of SSL) channel protection can be hardened through the use of client certificates. This method provides public key-based security when you connect to Tresorit servers.

pCloud Crypto

To guarantee your files’ safety, pCloud uses TLS/SSL encryption, applied when information is transferred from your device to the pCloud servers. At pCloud data security is our top priority and we do our best to apply first class safety measures.

With pCloud, your files are stored on at least three server locations in a highly secure data storage area. Optionally, you can subscribe for pCloud Crypto and have your most important files encrypted and password protected. We provide the so-called client-side encryption, which, unlike server-side encryption, means that no one, except you, will have the keys for file decryption.

They use industry standard 4096-bit RSA for users’ private keys and 256-bit AES for per-file and per-folder keys. We do data authentication in a different way compared to most competitors. Authentication is the process of verifying that you decrypted data with the right data. Many experts consider it a mandatory part of encryption.

      They’re not backup softwares. 1To for a cloud storage service is not less than the big names.

    Sync.com should be on here with it’s possible 10TB per user minimum 2 users for a few hundred per year.

    Also single user 2TB accounts.

    Comes with all the secure end-to-end encryption and other features the best ones have.

    The only downside is no monthly payment option.
