Our Verdict

Tresorit’s most impressive feature is its security, with end-to-end encryption and zero-knowledge storage. But this level of security comes at a price.


  • Zero-knowledge end-to-end encryption
  • Free encrypted file-sharing service


  • Pricey
  • Few in-app collaboration features

Tresorit is a cloud storage service with a particular focus on enhanced security and privacy. With simple-to-use apps for Windows, macOS, Linux, Android, and iOS, Tresorit enables you to keep a safe and secure backup of your most important files and access them from anywhere.

In our Tresorit review, we pit it against better-known services like Dropbox and OneDrive to see whether it should be considered the best cloud storage solution available today.

Tresorit: Plans and pricing

Tresorit has a free file-sending service, two paid plans for individuals, and three paid plans for businesses. The file-sending service doesn’t include any permanent storage space, but you can temporarily host files up to 5 GB in size for up to seven days. Each file can only be downloaded a maximum of 10 times.

The Premium plan ($12.50/month) includes 500 GB of encrypted storage. Choose the Solo plan ($30/month) for 2.5 TB of storage, enhanced control and tracking, and a 10 GB maximum file size.

Business plans start at $25/user/month, with 1 TB of secure storage per user, administration controls, and Outlook integration. For 10 or more users, you’ll need the $15/user/month Business plan, which adds advanced admin controls, custom branding, and support for Active Directory. The $30/user/month Enterprise plan is for companies with over 100 users and includes features such as data residency options, support for single sign-on, and priority customer support.

Tresorit is a relatively simple cloud storage platform that’s differentiated by its commitment to strong security. The core software works much like other cloud storage apps, where you can sync files and folders on your devices to the cloud. You can share links to these files with people, even setting passwords and expiration dates on links if you wish. Tresorit supports file versioning, so you can roll back files to previous versions as necessary.

The company also has a virtual folder feature. Each virtual folder is called a “tresor” and can be filled with files and folders from anywhere within your cloud storage. You can invite people to each tresor, and they only gain access to the files in the virtual folder. It’s an interesting alternative to tagging that you can use to keep your cloud storage organized while limiting the files that team members can access.

Interface and in use

We really liked the Tresorit interfaces. They’re modern, professional, and uncluttered. The web interface is simple and loads quickly, and the mobile apps are all snappy and intuitive.

In our testing, upload and download speeds were good. The Tresorit servers are hosted on fast network infrastructure, so most businesses will be limited by their local network connection speed before being throttled by Tresorit. We also like that the client apps have a throttle setting so your web connection doesn’t slow down when you’re syncing. Being able to store files solely on the cloud storage instead of syncing to every device can save bandwidth and hard disk space.

Tresorit’s website has a solid knowledge base that covers all facets of the software and how to use it. It’s frequently updated and includes useful screenshots.

Further support is primarily done through tickets and live chat, though higher-tier business plans get priority assistance and support via phone. In our testing, Tresorit replied to our queries in a matter of minutes, making it much more responsive than almost all the cloud storage services that we’ve reviewed.

Tresorit supports end-to-end encryption. This means that files stored on the servers and in transit are always encrypted. The service is also zero knowledge, so files can’t be decrypted without the correct decryption key. Only you have the decryption key; even Tresorit staff don’t know it, and hackers and law enforcement can’t access your files. 

You can also choose to enable two-factor authentication for an extra level of security.  When you share links to files, you can password-protect them and make it so they automatically expire. You can also set your files to only be accessible from certain IP addresses. Basically, Tresorit’s security features are top-notch.  

Tresorit has run several hacking contests where the company offered increasingly big rewards to anyone who could hack its servers. To date, no one has been able to claim the reward.

The competition

If you don’t need the extremely high level of security on your files that Tresorit offers, iDrive gives you cloud storage for much cheaper. You can get a 10 TB plan for $99.50/year, for example, and there are further discounts for paying multiple years in advance.

If you’re looking at Tresorit for its strong security, you could also consider the open-source Nextcloud platform. It’s a free private cloud service with support for zero-knowledge end-to-end encryption, though be prepared to spend much more time setting it up.

Final verdict

Tresorit is one of the most secure cloud storage services available today, though it isn’t the cheapest service out there. That said, the apps and web interface are slick and professional. If business security is your primary concern, Tresorit is a superb choice.
