What is Tresorit?

Tresorit is a zero‑knowledge, end‑to‑end encrypted cloud collaboration platform built for organizations and individuals who need maximum control over sensitive data. It enables secure file storage, synchronization, and sharing while ensuring that only the data owner and explicitly authorized users can access content. Files are encrypted on the user’s device before upload, and encryption keys are never accessible to Tresorit, protecting data from internal access, breaches, and unauthorized disclosure. The platform supports secure internal collaboration through encrypted folders and workspaces with granular permission controls. Teams can define who may view, edit, or manage files, revoke access at any time, and track activity to maintain visibility and accountability. Tresorit also enables secure external sharing via encrypted links and protected email delivery, replacing risky attachments and unsecured file transfers with controlled, auditable exchanges. For client‑ and partner‑facing collaboration, Tresorit provides encrypted data rooms that centralize documents, tasks, and approvals in a single secure environment. These data rooms are designed for ongoing collaboration rather than one‑off transactions, allowing organizations to manage long‑term external projects while maintaining strict confidentiality. Integrated digital signatures make it possible to review and sign documents without leaving the encrypted workspace, preserving security throughout the entire document lifecycle. With advanced administrative controls, audit logs, and configurable data residency options, Tresorit is built to support compliance with strict data protection and regulatory requirements. By combining strong security with intuitive usability, Tresorit enables productive collaboration without compromising privacy, ownership, or trust.

What is FileString?

FileString is an intuitive cloud-based service that adds a digital string to important files you distribute, allowing you to oversee and control how recipients interact with your documents, including their ability to view, download, and print them. This straightforward file-sharing solution ensures the protection of your vital files. With FileString, only those you specifically allow can access, forward, or print the documents you send. You can monitor recipient engagement meticulously, tracking details such as the duration of their file views, and you will receive notifications via email whenever files are accessed, printed, or downloaded, depending on the permissions you set. Your library is neatly organized by individual, providing a clear view of all files sent to each recipient, as well as any files they have shared back with you. Should you need to, with a simple click, you can revoke access to all files shared with a particular individual, thus maintaining strict control over your documents. Furthermore, you can elevate the security of your files by adjusting each recipient’s permissions for viewing, forwarding, printing, and downloading, while also having the option to incorporate a watermark for added protection. If circumstances change, you can swiftly remove access for specific recipients, effectively ensuring they can no longer retrieve any distributed copies. This robust level of control and security makes FileString an essential resource for anyone tasked with sharing confidential information safely and efficiently. Additionally, its user-friendly interface ensures that even those who may not be tech-savvy can navigate the platform with ease.
