Why FTAPI is the secure alternative to Tresorit for your data processes.
Looking for more than just encrypted cloud storage? Then FTAPI is your alternative to Tresorit: a platform that automatically encrypts emails, structures incoming data, and securely automates processes. Made and hosted in Germany.
Why businesses are looking for alternatives to Tresorit.
Secure file sharing is only the beginning
Tresorit is a well-known solution for encrypted file sharing. However, modern corporate data exchange rarely happens through shared folders alone: data arrives via email, is submitted through forms, requires approval, must be forwarded to external partners, and needs to be logged in an audit-proof manner.
Anyone looking to secure every one of these points needs a solution that covers the entire data flow – from initial receipt to seamless documentation..
Data sovereignty without compromise
In certain plans, Tresorit offers customers the option to choose where their data is stored. However, the infrastructure runs on Microsoft Azure—a US-based provider generally subject to the Cloud Act. Many organisations in regulated sectors or the public sector prefer a Tresorit alternative that is hosted by a German provider in German data centres and offers certifications such as BSI C5 Type 2. This ensures that data sovereignty is maintained.

FTAPI SecuRooms: Security that adapts to your daily work routine
Your data is consistently sealed within FTAPI SecuRooms. Security and usability are perfectly balanced: while solutions focusing solely on end-to-end encryption can sometimes restrict workflow, FTAPI offers encryption tailored to your specific needs. Depending on the criticality of your data, you can choose the appropriate security level – up to end-to-end encryption.
All levels are GDPR-compliant. When collaborating with external partners or auditors, you can also precisely control access and maintain seamless logs. In the appropriate tiers, FTAPI also allows for automatic virus scanning during upload. This creates a protected data room that is as secure as necessary and as simple as possible.
Unifying all data exchange on a single platform
FTAPI closes the gap left by traditional cloud providers with their isolated solutions. Instead of juggling different tools for file sharing, secure emails, and data collection, you centralise all data exchange on one central platform. Email encryption is directly integrated and can run automatically in the background, without the sender having to make a manual decision for every single email.
You receive data from external parties in a structured manner via secure online forms. And with SecuFlows Advanced, you can digitalise and automate recurring data processes without requiring specialist programming knowledge. This platform approach ensures that your data exchange is GDPR-compliant while remaining efficient. You replace manual tasks with automated, protected workflows.

Frequently asked questions.
There are numerous alternatives to Tresorit. For purely private cloud storage, users often turn to tools like Dropbox, while in the enterprise sector, solutions like SharePoint are frequently used for document collaboration. Which solution fits best depends on the requirements for data security and functional scope.
Businesses that want to protect sensitive data comprehensively, automatically encrypt emails, and automate data processes often rely on a specialised platform like FTAPI. This is also BSI C5 Type 2 audited and is operated entirely within Germany.
Data residency describes the country in which data is physically stored. The hosting provider is the company legally responsible for the infrastructure. Tresorit stores data in the EU upon request – however, the infrastructure is operated by Microsoft Azure, a US company. Under the Cloud Act, US authorities can demand access to data regardless of its physical location. FTAPI operates its cloud infrastructure via SysEleven GmbH (part of secunet) in Frankfurt am Main.
Tresorit is ISO 27001 certified and holds certificates such as EAL4+ as well as the Swiss Digital Trust Label. As of May 2026, Tresorit does not hold a BSI C5 Type 2 audit report. This audit is the definitive standard for cloud security in Germany and is mandatory for many public authorities and regulated sectors. FTAPI is BSI C5 Type 2 audited (verified by HKKG).
FTAPI is particularly suitable as a Tresorit alternative for large files, as it supports sending and receiving files of up to 100 GB. While many cloud services impose limits at around 20 GB, FTAPI reliably supports the exchange of large technical datasets or medical reports.
