Tresorit Review

Tresorit cloud storage offers excellent business security, but it comes at a price. However, if you can shell out a few dollars and learn its unique system, there are few storage services as secure as Tresorit. Read our full Tresorit review for all the details.

Tresorit is one of the largest names in cloud storage, sitting alongside services like and Dropbox in our best cloud storage rankings (see our Dropbox vs Tresorit comparison). Although it’s a decent option for personal use cases, Tresorit comes into its own in a business context, sitting near the top of our best business cloud storage rankings. 

In this Tresorit Business review, we’re going to explain why. From features to security and privacy, we’re going to cover everything that the service gets right, as well as the few unfortunate things it gets wrong. 

In short, the Tresorit cloud is excellent for business security, but that comes at a price. The literal price is high, but Tresorit taxes you in other ways, too, forcing you to learn and understand its system. Once you do, though, there are few storage services as secure as Tresorit.

Tresorit gets the basics right, so rest assured that if you need a specific feature, Tresorit probably has it. Short of block-level sync — more on that in the “security” section below — Tresorit has a little bit of everything. Most of the features are small and only come up in specific use cases, so consult Tresorit’s website if you’re looking for a specific feature. 

Starting with the basics, Tresorit has an app for just about everything. Your browser works — even if you’re on the personal Tresorit free plan — as do the desktop apps for Windows, macOS and Linux, as well as the native mobile apps for Android and iOS. There’s also a command line interface for Linux, if that’s your jam. 

Privacy and security features are excellent across these platforms, too, including a zero-knowledge model and multi-factor authentication options. Along with those features, Tresorit includes some nifty (if not all too useful for businesses) features. Those include auto camera upload, encrypted scanning and offline access.  

Encrypted File Sharing

We’ll talk in detail about file sharing in the appropriate section below, but you can send large files through Tresorit easily with its file sharing capabilities. You can send files up to 5GB using an encrypted link. This link uses the same end-to-end encryption as if you were sharing files within your own account. 

It goes deeper than simply sending a link, though. You can change access permissions, revoke access to a link and choose if the recipient can see the version history or not. Tresorit even has Outlook integration. No more unencrypted email attachments. 

Network Drives

If you’ve used Google Drive or Dropbox before, Tresorit is a walk in the park. Like those services, you can easily upload and download files from your account using a local folder on your computer. The files within that folder, of course, take up space on your hard drive. If you’re running low on space, you can set up a Tresorit Drive. 


Tresorit Drives are virtual network hard drives mounted to your computer. You can open the drive and browse through the files like you would any local hard drive, but the contents inside don’t take up space on your computer. The only downside is that you can’t move or rename folders. 

In place of WebDAV, Tresorit drive is a solid solution. In fact, there aren’t really any Tresorit alternatives in this regard. Although there are some limitations, Tresorit Drive essentially allows you to have a full hard drive in the cloud, which is great for saving space on your local machine. Even better, it’s included with every subscription.

Data Residency, Access Logs and File Versions

Although the above Tresorit features are flashy and impressive, these next few are probably the most important for businesses. All of the data in your account has a history attached to it, and as an administrator, you can view that history at any time. As we’ll get to later, you can also set security policies for your business and monitor usage statistics. 

Included with the history is a version list for each file. Tresorit automatically stores a copy of everything, you can revert to a previous version at any time. In the case of a cyber attack, where you may need to delete files in order to save them, you can restore that data within Tresorit. 

Users can monitor every login attempt, as well as the attempted login credentials and where the attempt came from. Business storage is one of the few areas where more control is better. With Tresorit, you’re given the tools to monitor your account and adjust your security policy accordingly. 

Finally, Tresorit offers data residency options. As an enterprise storage service, Tresorit recognizes that where you keep your data is important, not only for security but also for local regulation. 

When defining a security policy, you can choose where Tresorit hosts certain data. The options include Tresorit’s homeland of Switzerland, which is known for its excellent privacy laws.

Tresorit Pricing

65 % – Decent

Tresorit is a hell of a business storage solution, and it knows that. Outside of a decent free plan for personal use — emphasis on “decent,” here — Tresorit is one of the more expensive options on the market. Considering its features and security, the price is worth it. Still, your wallet will be lighter as a result.

Small Business
  • Price per user (billed annually),Storage per user,User count: 3-9 Details
  • 1000 GB Storage
1-year plan $ 20.00/ month
$240.00 billed every year
  • Price per user (billed annually),Storage per user,User count : 10+ Details
  • 1000 GB Storage

  • Price per user (billed annually),Storage per user,User count : 100+ Details
  • 1000 GB Storage
1-year plan $ 24.00/ month
$288.00 billed every year

You have three options as a business subscriber: Small Business, Business and Enterprise. Small Business is truly focused on small outlets, with a minimum of three users and a maximum of nine. 

Compared to the standard Business plan, the Small Business plan is missing a few things, namely SSO integration with services like OneLogin and some advanced reporting features. It’s only slightly cheaper, though, so an upgrade is worth it. 

In fact, a full, fat Business plan is cheaper than a Small Business plan out of the gate. Exclusively for 10 users or more, it comes with a 50-percent discount on your first term. That brings the price closer to pCloud — read our pCloud review for the full details — but still, Tresorit is more expensive than the competition. 

At the top is the Enterprise plan, which includes SSO support, personalized training staff and immediate phone support. Otherwise, it’s the same as a Business subscription, price and all. That said, an Enterprise plan is only for teams of 100 or more, and you’ll need to contact Tresorit for a custom deployment. 

The kicker to all of this is that Tresorit offers 1TB of storage per user; no more, no less. Compared to a service like, which offers multiple storage options for businesses, Tresorit is lacking. Although 1TB is more than enough in a lot of cases, there are some scenarios where it’s simply not enough. Visual effects houses, in particular, come to mind. 

After a quick glance at Tresorit’s competitors, it becomes abundantly clear that you aren’t getting a deal. Tresorit is all about security, whereas a lot of other cloud storage platforms balance storage space with price. Of all the things Tresorit gets right, pricing isn’t among them. 

Ease of Use

80 % – Good

Tresorit isn’t inherently difficult to use. In fact, once you learn its idiosyncrasies, it’s easy to use. However, the way it approaches certain things can make onboarding more difficult than it needs to be. Due to its security model, there are some creature comforts missing, too. For instance, you can’t stream music from Tresorit like you can with pCloud or  

Starting with the web app, everything is straightforward. You can view your folders, manage your account settings and select different options for files by right-clicking them. It’s not quite as fluid as a Google Drive, OneDrive or Dropbox account, though. 


Tresorit uses tresors in place of folders. The word “tresor” is German, roughly translating to “vault” or “safe.” These aren’t standard folders, though. Everything must go inside of a tresor, so you can’t upload files to the root directory of your account. Likewise, you can’t drag and drop files into the web app like you can with, say, Google Drive. 

There’s a reason for this approach. Tresorit encrypts each of your tresors using your password, and inside each tresor, it stores the encryption keys for each individual piece of data. 

Logic usually doesn’t win against usability, and such is the case here. No matter if you want to share files or upload something new, Tresorit makes doing so simple. However, you’ll have to learn what its definition of “simple” is. 

Desktop and Mobile Apps

Tresorit is one of the rare few online storage services that supports Linux, which automatically places it near the top of our best cloud storage for Linux guide. Additionally, it supports Windows and macOS, as well as apps for Android and iOS mobile devices. No matter where you are or what device you’re on, you can access your account. 

The desktop app mirrors the web one, though with a slightly condensed interface. There’s no reason to belittle any readers here; if you’ve used any cloud storage service before, you’ll appreciate how everything’s within reach in Tresorit’s app. 

However, the only unique thing we found is the ability to pin Tresors, allowing you to quickly manage certain folders no matter where you’re at in your account. 


On mobile devices, Tresorit carries the same straightforward design philosophy, though it allows you to automatically upload things like photos. Although not useful for businesses, having access to your account on the go is never a bad thing. 

This section is tough. Tresorit plays by its own logic, so as long as you understand how the system works, it’s very easy to use. There are a few minor issues, and although we understand why those issues are present, we don’t expect that every new Tresorit user will. We’re taking off a few points because of that, but rest assured that Tresorit has excellent design overall.

File Sharing & Syncing

90 % – Excellent

Tresorit’s sharing and syncing capabilities are world-class thanks to its excellent versioning. It made the list in our best cloud storage for sharing guide for a reason, after all. 

Starting with sharing, you can share tresors with other users easily in the web application. Simply mouse over the tresor you want to share and click the appropriate button. 

However, you can only fully share a tresor — the main folder — but you can’t fully share the folders within it. In this case, “fully share” means that the tresor shows up in the recipient’s account. The tresor is encrypted using your password, and it holds the encryption keys for all of the files inside. You can only share specific files or folders through a link. 

Link sharing is surprisingly robust, though. You can set an expiration date, set an open count limit and even choose if the opener has access to usage logs. If you share through a link, the opener doesn’t need an account, either. For full sharing, your recipient will need an account. 


None of this is particularly impressive, much less unique, for an enterprise storage solution. It’s within the simplistic system where Tresorit shines. Features like Tresorit Path, which allows you to easily copy the folder path of a specific file, are immensely useful in the often crowded corporate storage spaces. 

Our favorite feature is file requests, though. Essentially, file requests allow users outside of your network to upload a file directly to a tresor. Say your business is using a consulting firm. You can send a file request to the firm asking for their report, and they can upload it directly to Tresorit, no account required. 

Tresorit Syncing and Versioning

Out of the gate, Tresorit will automatically sync your files, so no matter if you’re using the web portal or the local application, you’ll have access to your files across every platform. If you don’t want to share everything, Tresorit supports selective sync. With it, you can choose which files you want to update in the cloud instead of just updating everything. 


You have full access to every version of a tresor or file within your account, too. Whenever you change or overwrite a file, Tresorit automatically stores a version of the older file. If the file becomes corrupt or you need to revert for any other reason, you can easily do so in the web or local application. 

With how quickly files are updated in a corporate setting, having access to previous versions is an invaluable tool. Plus, with businesses being a prime target for cybercrime, it’s always a good idea to have a backup.


75 % – Good

As always, we tested Tresorit Business using a 1GB test folder. Before running the speed test, we took our raw connection speed at around 400 Mbps download and 20 Mbps upload, meaning our 1GB folder should have been off our hard drive and into the cloud in record time. Unfortunately, that wasn’t the case.

 First Attempt:Second Attempt :Average:

The download speeds, in particular, are painful. During our trial, the majority of the folder downloaded quickly, before hanging at 97 percent for over five minutes. This behavior continued into our second trial — though with an additional 30 second tax — suggesting the problem is on Tresorit’s end.

Upload times are far more reasonable — and more importantly, explainable — considering that Tresorit’s servers are located in Ireland and the Netherlands (we were testing out of the U.S.). Ignoring encryption, we would expect around a seven-minute average upload time. Tresorit takes longer, but not too much longer. 

The main killer is that Tresorit doesn’t support block-level sync. This isn’t possible with end-to-end encryption, meaning every time you update a file, you’ll have to fully reupload that file.

Egnyte Connect supports block-level sync for all files, as well as selective sync, though at the cost of encryption.


95 % – Excellent

Tresorit is very safe for businesses thanks to its end-to-end encryption. In short, your files are encrypted before ever being sent over the internet, and they are decrypted only when you or a collaborator accesses them. Tresorit is a zero-knowledge service, meaning it can’t access your files, even if it wanted to. 

Here’s how the process works: when you upload a file, Tresorit employs the AES-CFB algorithm to generate a 256-bit key. That encrypted file passes through a HMAC-SHA512 hashing layer before being signed by a digital signature. Wrapped up in a bundle of cipher text, the secure file then passes through a SSL/TLS channel and into Tresorit’s cloud storage system. 

If that sounds like a bunch of nonsense to you, make sure to read our description of encryption. If the gory details don’t concern you, know this: Tresorit is secure by design, protecting you not only from external threats, but from Tresorit itself. 

As most businesses know all too well, though, your employees are often the greatest source of vulnerability. Sharing between users is handled with asymmetric encryption. Each user on your plan has their own X.509 certificate, which contains the private half of a RSA-2048 key pair. This certificate is then authorized using the other user’s certificate, and the keys are paired. 

More importantly, though, the owner and admins of a Tresorit business account can define security policies across their storage, including timeout policies and IP filtering. Furthermore, owners can monitor usage statics and, perhaps most importantly, remove access from particular users and devices.


100 % – Excellent

Tresorit is a highly secure business cloud storage solution, so it shouldn’t come as a surprise that it respects your privacy, too (Dropbox Business, take notes). In what is one of the clearest privacy policies we’ve ever seen, Tresorit lays out what it collects, why it does so and how that impacts your privacy. 

At a top level, Tresorit doesn’t log much of anything. Outside of obvious information, such as your billing information and name, Tresorit doesn’t dig into your files or spy on what you’re doing with them. That simply isn’t possible given the zero-knowledge encryption model of the service. 

There are a few things Tresorit can see, though, including the names of folders, size of folders and the members attached to them. This isn’t a problem, and Tresorit sums up why better than we ever could: “For the avoidance of any doubt, Tresorit cannot connect such metadata information to Your Encrypted Content or file names as Tresorit has no access to the Encrypted Content or file names.”

As is the case with nearly all cloud storage services, Trresorit will share your information in compliance with Swiss law — a high bar to clear, with Switzerland sporting some of the best privacy laws in the world — and to market Tresorit services to you on different websites.

However, you can opt out of these communications in compliance with GDPR

Between the TL;DR snippets for each section and Tresorit’s clear wording, anyone can dive into the privacy policy and get a sense of how Tresorit is handling their data. That’s more than most cloud storage services can say, and this alone puts Tresorit ahead of the pack. The fact that the privacy policy isn’t menacing is the cherry on top.

Customer Service

90 % – Excellent

Tresorit splits up its support based on your subscription. Small Business subscribers have access to the basics: live chat and email support. Up the chain, Business subscribers have access to priority email support — within the same day, based on our estimation — as well as scheduled phone support. 


Enterprise subscribers get everything, from immediate phone support to personalized staff training. Despite the fact that Tresorit breaks up its support options, we’re happy to see live chat and email support span every plan. Plus, the knowledgebase is open to everyone, and it has articles for just about everything.


The best way to describe the content in Tresorit’s knowledgebase is “engaging.” Articles don’t unnecessarily drone on, but at the same time they provide enough detail so you aren’t left with more questions than when you started.

Tresorit Verdict

Tresorit, above all else, is unique. It doesn’t use the same playbook as other cloud storage services, rather embracing limitations in favor of stricter security. It’s not a perfect enterprise cloud storage solution. Where security matters more than all else, though, Tresorit shines. 

What do you think of Tresorit, though? Let us know in the comments below and, as always, thanks for reading.

  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. 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. 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. 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).

  7. This product is horrible and the support is practically nonexistent. I tried using it for my firm and the files got badly out of sync and we lost data. I’ve had to go through a complete review to try to get my data back in sync. It’s not uncommon to send a support request and not hear back for a week. Or, to hear back with a query as to whether the request can be closed. I wouldn’t use this product for anything that I cared about losing.

  8. After some investigation, I picked Tresorit about 2 years ago for a non-profit that I used to work with. I liked it so well that I subscribed personally…
