Is Tresorit worth it?
Tresorit suits businesses that handle confidential files and want end-to-end encryption, with a free trial of 14 days on any plan.
Whether it is worth it depends on team size and compliance needs. Business pricing is per user, starting at $23.20 / user / month for at least 3 users, while the Professional plan costs $32 / month for 1 user. Enterprise pricing is custom, so larger deployments need a sales conversation before they can budget.

How we evaluated Tresorit
This Tresorit review is based on reading the company's own public pages, including the home page, pricing, security, privacy, legal and contact pages.
HostSiftly did not sign up for or test Tresorit. The review uses the published plan prices, feature lists, security statements, privacy policy, legal index and contact details, and it relies only on what those pages say.
Customer stories on the site are chosen by the vendor, so they are not used here as a measure of how customers feel about the product.
Tresorit output quality and limits
The security pages describe zero-knowledge encryption, RSA-4096 key sharing and data residency options, while plan limits such as file size vary by plan.
How Tresorit protects files
Tresorit encrypts files on the device before they reach the cloud, and only the user and chosen recipients hold the keys. Key sharing uses RSA-4096 with OAEP padding and PKI certificates. Clients also apply HMAC or AEAD authentication, so a file's content cannot be modified without the user's knowledge.
Residency, login and plan limits
Data residency can be set to EU-only or to any of 12 global locations, to meet regional compliance requirements. Two-factor authentication is listed among the features all plans include. The Professional plan lists 4 TB encrypted storage and a 10 GB maximum file size.
Tresorit key features
Tresorit sells several products on one platform, with SecureCloud for encrypted storage, Engage for data rooms and eSign for signatures.
SecureCloud and file exchange
SecureCloud is sold in Professional, Business, Business Pro and Enterprise tiers. The Professional plan lists 4 TB encrypted storage, a 10 GB maximum file size and 16 eSignatures for free. FileSharing lets users exchange files with anyone confidentially. SecureCloud also runs on Windows, macOS, Linux, iOS, Android and the web.
Engage, eSign and email encryption
Engage provides secure, branded data rooms for collaborating with clients and partners. eSign is also listed among Tresorit's products. Email Encryption works directly from Outlook and Gmail to encrypt messages and attachments.
Tresorit pricing and plans
Tresorit publishes per user prices for Business and Business Pro, and a monthly price for one user on Professional.
Professional costs $32 / month for 1 user, Business costs $23.20 / user / month with at least 3 users, and Business Pro costs $28.80 / user / month with at least 5 users. Yearly billing is shown with a 20% OFF label on the pricing page.
Enterprise pricing is custom and billed annually, so larger deployments need a sales conversation before they can budget.
Support, refunds and cancellation
Tresorit offers free support by email or chat, a trial of 14 days on any plan, and cancellation at any time with a downgrade to the Basic plan.
Support channels
Support is free through email or chat, according to the pricing page. The contact page lists separate channels for Sales, Support, Security, Press, Abuse and Authority Requests. The team typically responds within 1 business day.
Trial, billing and cancellation
Any plan can be tried for 14 days without limitations, but payment information is required during the trial. Subscriptions can be cancelled at any time, and the company says you can downgrade to the Basic plan.
Who should use Tresorit
Tresorit suits businesses that handle client data, contracts or intellectual property and need encryption that the vendor cannot read.
Teams that exchange sensitive files with clients or partners fit the Engage and FileSharing products best. Small teams can start with Professional, while teams of at least 3 users look at Business and larger groups at Business Pro. Buyers who need a fixed published price for a large group should expect a sales conversation.
Final verdict on Tresorit
Tresorit is a strong option for regulated teams that need encryption the vendor cannot read, with published prices and a trial of 14 days.
Based on the company's published pages, it fits buyers who put zero-knowledge encryption and data residency ahead of the lowest price. Compare the per user cost of Business and Business Pro with your team size, and ask sales about Enterprise pricing if you need custom terms. HostSiftly did not sign up for or test Tresorit, so this verdict relies only on published information.
