Cloud Storage Reviews

Tresorit is one of the most secure and private cloud storage solutions thanks to its zero-knowledge encryption and approach to syncing files and folders. On top of that, it has many other security features.

That comes at a price, though, and one that’s higher than almost every other cloud storage service. Another of its drawback is that there are no collaboration or productivity apps because of its zero-knowledge encryption.

It has strong sharing capabilities, too, along with content control options that help keep your shares secure.

Tresorit is worth a look if you value your security and privacy and don’t mind the higher cost. If it isn’t what you need, though, you can find other services on our cloud storage reviews page. For those who need a business cloud storage solution, we have a best enterprise file sync and share providers guide, too.

Tresorit provides secure cloud storage with a focus on privacy. The foundation of its approach is private, end-to-end encryption — also called zero-knowledge encryption. We’ll talk in more detail about it in the security section, below.

Tresorit doesn’t integrate with third-party apps, such as Office Online or Trello, because zero-knowledge encryption doesn’t play well with them, which limits opportunities for increasing productivity and collaboration with others. At least its excuse helps your privacy. For a different approach, see our best cloud storage for collaboration piece.

For the same reason, you can’t preview or edit files in Tresorit, nor can you stream music or other media. For productivity, Google Drive, Dropbox and OneDrive are the best bets. If you need audio and video playback, read our best cloud storage for music and best cloud storage for video articles to see which service provide it.

Tresorit can sync your files and folders but it also has a network drive feature called Tresorit Drive. The difference between a sync folder and a network drive is that sync folders store files and folders on your computer and in the cloud, while network drives only store files in the cloud. Tresorit Drive is a good way to save space on your hard drive.

Tresorit provides an add-on for Microsoft Outlook, too, which provides a more secure means of sharing files than normal email attachments.

For Linux users, Tresorit offers a simple command-line interface that runs on Linux workstations or servers. It has fewer features than the graphical Tresorit client, but you can use it to automate tasks such as sync and reporting.

Tresorit has strong versioning capabilities, too, earning it a place on our best cloud storage for versioning list. You can use versioning to roll back file changes if you get hit by ransomware, someone accidentally changes the file or it’s corrupted by a disk error. Tresorit’s versioning is unlimited for paid accounts other than Premium.

Premium is the cheapest plan, yet it costs $10.42 per month for 200GB. That’s more than some charge for 2TB. For example, pCloud’s 2TB plan is only $9.99 a month. You can see the complete pCloud pricing table in our pCloud review. The other personal plan, Solo, provides 2TB of space for $24 per month. There’s no free plan, but the paid plans have a free trial period.

Tresorit offers business plans, too. Small Business costs $20 per user per month and gives you 1TB of storage for each user. Business is currently 50 percent off and costs $12 per user per month. It improves on the previous plan with additional features, such as advanced file control and support.

Enterprise costs $24 per user per month and enables you to have more than 100 users, use admin API and give staff training.

Ease of Use

79% - Good

Ease of use can break a service even if it has strong features. The reason for that is users will steer clear of a service that’s difficult to use or doesn’t work like it’s supposed to. None of the services on our best cloud storage ranking fall into that category.

That said, Tresorit is more complex to use than the average service because the desktop client requires you to create tresors — that means “vault” in German — and sync them individually. It’s not rocket science, but it might be tiresome for mainstream users. If you find yourself in that category, give Dropbox a try. Read about its approach in our Dropbox review first, though.

The desktop client works on Windows, macOS and Linux. The Linux addition is somewhat rare among cloud storage services. See our roundup of the best cloud storage for Linux for other options.

The desktop client is clear and easy to use. There’s no accounting for taste, but, to our eye, the Tresorit desktop client is one of the most attractive on the market. The menu on the left lets you navigate to recent activity, your tresors, shared links, account and settings.

If you’re on the move, you can use the Tresorit web app to access the same features. It has plenty of negative space, which makes folders and navigation links easier to find. Like the desktop app, it has a menu on the left that helps you navigate it.

Because you need to make individual tresors to sync files, you can’t drag and drop content into the root folder of the web client. That makes sense because it’s not a tresor, but the approach is atypical.

That said, performing actions on files and folders is easy because you can just right-click them and select the action you want or use the three dots that appear when you hover over them.

Tresorit also has mobile apps for Android and iOS. They can be used to upload mobile files such as pictures and videos and access your cloud storage. It also lets you create links to your content and work offline. If you want to make sure only you can access the app, you can set a passcode lock.

One quibble, though, is the location of the menu button. Unlike mobile apps from other services, Tresorit’s app doesn’t have a standard menu button that’s visible right away, but rather it keeps it behind the three dots in the upper right corner. That’s a minor thing, but accessing the menu faster is more convenient.

File Sharing & Syncing

89% - Very Good

Sharing is one of the staples of cloud storage services and you’re probably going to do it often. Tresorit is on our list of the best cloud storage services for sharing thanks to its strong content control options and sharing capabilities. You get the same sharing features whether you use the web or desktop app.

You can share content with specific individuals via email or generating a link and copying and pasting it. You can share a folder by generating a link or inviting users via email. If you use an email to share a folder, the recipients will need to register for a Tresorit account. Files can only be shared with a link and don’t have that requirement.

You can protect links using a password, expiry date or download limit. Folders have three levels of permissions. They are “manager,” which can share, edit and view; “editor,” which can read and modify; and “view,” which can only read.

There’s a “links” view to help you keep track of the links you’ve created. Another tab, “contacts,” shows which people you’ve shared folder access with. There’s no way to create upload links or share to social networks, though.

You can use Tresorit to sync content between devices, but it also lets you only store files in the cloud via its network drive feature.

Unlike other cloud storage services, Tresorit doesn’t have a single sync folder. Instead, it asks you to create tresors for every folder you want to sync.

You can do so from the app or you can right-click a folder and select “create a tresor.” If you create it using the app, you will need to turn sync on. Once it’s on, the tresor will be added to a special Tresorit file system folder called “synced tresors.” To only sync specific folders in your tresor, you can use the selective sync feature.

You can copy and paste files to any of your tresors to sync them or use the desktop client, which supports drag-and-drop.

Speed

85% - Very Good

Your transfer speeds will depend on our internet service provider and how close you are to a server. Tresorit’s servers are in Ireland and the Netherlands. We did our tests using a WiFi connection in Belgrade, Serbia, with an upload speed of 6 megabits per second and a download speed of 100 Mbps. Because we weren’t on the other side of the world the results were good.

Upload took the same amount of time we would expect it to take, even with end-to-end encryption. It averaged 23 minutes for a 1GB file, which is quite fast.

TestsFirst attempt:Second attempt:Average:
Upload time00:24:0000:22:0000:23:00
Download time00:03:5700:04:0300:04:00

The download speeds didn’t suffer from added time because of encryption, but, with a four-minute average, they were slower than they should be. The fastest time we could expect is a minute and a half.

Tresorit doesn’t have block-level sync, which would speed up the transfer of files that have already been uploaded by only sending the changed portions. The reason it doesn’t have it is because zero-knowledge encryption doesn’t work with the feature, but a representative told us it is planned.

If you find that Tresorit interferes with your work or you’re on a limited data plan, you can set a limit on network bandwidth by going to the “network” tab of the settings menu in the desktop app. There’s no limit by default.

Security

99% - Excellent

Tresorit’s key point is security, and the main feature of its security arsenal is zero-knowledge encryption. It’s one of the rare services that offer it, which helps it bump shoulders with some of the best zero-knowledge cloud storage services, such as SpiderOak ONE, MEGA and Sync.com. Our top pick there is Sync.com, which you can read about in our Sync.com review.

Keep in mind that, though Tresorit uses zero-knowledge encryption to protect your privacy, it won’t be able to reset your password if you lose it. If you want to be sure you won’t, try a password manager from our best password managers article.

The TLS protocol prevents man-in-the-middle-attacks from succeeding, and encryption secures your data in-transit and at-rest. Tresorit uses AES 256-bit encryption to do that.

Two-factor authentication will stop hackers who’ve stolen your password from accessing your account. Still, you should make sure you have a strong password, to begin with.

Tresorit’s data centers employ 24/7 security, surveillance and biometric scanning. They are compliant with the latest ISO standards and run Microsoft Azure. Read our Microsoft Azure review for more on the service.

If someone steals your device, you can wipe the data on it remotely to keep the thief from getting to it. If malware corrupts your files and asks for ransom money, you can avoid paying by using file versioning to retrieve them, too.

More expensive plans let you define security policies for a set of users, as well as enable admins to monitor devices and revoke access from those devices.

Privacy

99% - Excellent

Tresorit is one of the most secure cloud storage services, but that doesn’t mean it’s lax with your privacy. Its headquarters are in privacy-friendly Switzerland and it keeps your data on servers in Ireland and the Netherlands, so you can be sure the service complies with the General Data Protection Regulation.

There are no questionable clauses in Tresorit’s privacy policy. In fact, it’s one of the clearest policies we’ve seen. To make things easier, buttons at the top of it guide you to specific questions. If you find them difficult to read there are boxes that give “in a nutshell” explanation to the right.

According to the policy, Tresorit doesn’t keep encryption keys or passwords in unencrypted form, so you can rest assured that zero-knowledge encryption will keep your privacy intact.

If you think your data isn’t correct, you can ask Tresorit to provide the information so you can check it. You can then correct inaccuracies or amend your personal data. If that doesn’t satisfy you, there’s an option to delete it, too.

If you’re in a country where the GDPR applies, you have additional rights, such as broader erasure of data and requests to stop processing your data.

Customer Service

83% - Good

Tresorit has chat and email support for all plans, but phone support is only available for Business and Enterprise. Support isn’t available 24/7, but a Tresorit representative assured us in an email that it is working on around-the-clock coverage. We sent a couple of questions to the technical support team and received a response within just two hours.

Before you contact Tresorit’s technical support, you can consult the knowledgebase. It’s split into categories that make it easy to find answers to common problems. If that doesn’t work, you can use the search bar to find your question.

The Verdict

Tresorit has strong security and privacy, but its paid plans are expensive because of that. Its desktop client is also more complex than those of other services. Its zero-knowledge encryption prevents it from working with third-party apps.

That said, it has impressive sync speeds, along with strong sharing and content control options. Its customer service is among the most capable we’ve tested, too.

Those that don’t mind paying more for strong security and privacy will be pleased with Tresorit. Others will probably stick with one of its competitors.

  1. Don’t go anywhere near Tresorit at the moment! The product has a way of handling file conflicts that means you can lose data! If it detects that there is a conflict in accessing a file, it renames the file on your local device and copies the one from their server back on to your device. The one copied back is likely to be an older file and you have not got a clue. Bearing in mind that this I promoted to aid collaboration between work colleagues, this scenario can go on to worse. Each collaborator gets a conflict and gets the old version downloaded whilst they believe they are making unique amendments to the file! I had this confirmed by an email from a Tresorit support person who said that they are looking into an alternative solution! This is just standard file locking protocol that should be implemented to prevent this sort of event!

  2. Hi, happy to read that I am not alone to have this problem with their synchronisation. I’ve just to add that their support even with a paid plan are totally absent. So I’ve unsubscribed has it’s impossible to use this system because some of your files is replaced by oldest.

  3. I’ve been using it within the free limit for a couple of years, I was looking to upgrade but never did.

    Here is why:
    – they don’t support all files! The ones that contain special characters in their names won’t get synced and they haven’t done anything to fix it over the years,
    – the referral program was removed without notice,
    – Tresorit app froze many times on my MacBook over the last few years and it is still not very stable. It also goes crazy when I have any Word document open in the background (Tresorit has some sync issues with open Word files),
    – Tresorit is significantly more expensive than their competitors,
    – they stopped replying to my emails, I guess their new policy is to reply to paying customers, which is fine but it does not encourage to pay for their service, given that it has so many issues.

    1. Hi Bart,

      We are pleased to say that Tresorit introduced support for special characters in June 2018. We have also released a number of updates to improve stability on all platforms, including Mac.

      We hope you’ll give us another chance in the future.

      – Tresorit Team

      1. hi Tresorit,
        Have you also addressed the sync/overwrite problems mentioned by previous users? That sounds like a serious issue. Thanks.

  4. Tresorit User Rating 1

    I loved everything about tresorit, from multiplatform syncing, to low CPU overhead, to sharing by links, and mostly the security. I had scored it 5 stars and called it perfect for years. But then last month it wiped my harddrive completely, system files and all, going well beyond folders I had synced through Tresorit. I restored my harddrive and it happened again, I caught it in the middle of deleting things and stopped only Tresorit, and the deleting stopped. I then restored from a backup on which I had deleted Tresorit. No disk wipes. I installed a shiny new Tresorit from disk image and it wiped my drive. Worst of all, every time it did this it viewed it as a new deletion and *removed all synced files from all my machines*. They told me to go through and restore each deleted file by hand (I had 1.6TB) and there was no bulk restore option (I wrote a script). Even when I did that, the Trash folder then had a copy of 2 versions of everything, filling my Tresorit account so I couldn’t even sync after restoring files to one machine! I told them about this, sent them the logs and they just said they wanted me to restore it again and send them more logs when it wipes my drive. Each time it wiped my drive, likely because of versioning on my local machines in a .tresorit/Trash folder instead of the promised cloud versionings, only my machine with a small harddrive close to it’s capacity seemed to have this disk wiping overflow effect, almost as if they mismanaged the drive space and overwrote e.g. filesystem tables. I finally had the courage to wipe all prior tresorit related configurations and re-install it after this sorely affected a major work deadline that jeopardizes my job. No deletions, again attesting that their program, its configuration and likely their local versioning destroyed a large part of my business.

  5. Tresorit User Rating 5

    Have been using Tresorit for years and always loved it. I did register a brief period of time when syncs generated conflicts but my files never got renamed but stored under the same name with the addition of a text highlighting the conflict. I contacted the support and got pretty swift response. The problem disappeared. For last 12-18 months everything’s been running fine. I cannot complain. Yes, it’s a wee bit expensive but it can be trusted.

  6. A quick price comparison between Tresorit and pCloud with encryption:
    -pCloud Premium (500GB) with Crypto comes to about 96 euros per year (8/month if pay annually)
    -Tresorit (200GB) fully encrypted costs about 100 euros per year or 8.33/month paid annually.

    If you need more than 200GB, then pCloud is the winner, but if 200 GB is enough then their prices are actually comparable.

      1. Tresorit User Rating 5

        I absolutely agree. Dealbreaker if you can’t store them locally. I’ve been using Tresorit for a little bit now on two systems dual booting both (windows + Arch) and it’s been a breeze. Installation on Linux is as easy as it gets and it’s super user friendly and has all the functionality that I need. Customer support has been good too (although not super quick always).
