Review Summary
Generated using AI from real user reviews
Tresorit earns strong marks for security, encryption, and interface design, but customer support is a weak point that frustrates some users.
The overwhelming majority of reviews praise the platform's encryption standards, intuitive design, and reliable performance over years of use. Users consistently highlight the browser interface and desktop app as seamless and easy to navigate, along with strong security features like passcode locks and secure file sharing. Several mention confidence in Tresorit's non-US base and lack of backdoor access. Long-term users report stable service with smooth updates and no degradation over time.
However, two significant complaints emerge. One user experienced a multi-week wait for support responses and unanswered questions, describing the service as unacceptable for small business owners without IT support. A second user reported being incorrectly billed twice despite using a free voucher, with unresolved customer service complaints and no phone escalation option. This reviewer questions the company's billing practices and transparency.
The reviews suggest Tresorit delivers on its core promise of secure cloud storage for long-term users, but responsiveness to support requests and billing issues can be problematic, particularly for newer or smaller customers who encounter friction during onboarding.

“This might be the best ever cloud service in the…”
This might be the best ever cloud service in the world but their customer service & billing practices are horrible. I joined this service on April 19th, 2016 through a voucher I received from KASPERSKY for a FREE 100GB of cloud storage, expiration date of the voucher is August 2016. upon registering my account, my credit card on file was billed 100 Euro on the same day, although it was stated on the site that my credit card will not be charged. I have communicated my issue to their customer service through email, I submitted a copy of the voucher as well as the activation code, yet they failed to resolve my issue. then on April 26th they charged my credit card again for the same transaction. They have no phone number listed on the site for escalation, no one to talk to, they are hiding in the cloud filing their bank account with money that they wrongfully collecting. So, think twice before you volunteer your credit card information on their site.
