The platform for confidential collaboration

5F brings documents, the queries about them and responsibilities together in a shared data room instead of scattering them across inboxes and folders. Every requested document shows its own status, and every query sits as a comment next to the document it relates to. Participants receive personal access with their own permissions, and every action is traceable in the immutable audit log. All content is stored exclusively in German data centres.

For your review, 5F provides the data processing agreement with the list of sub-processors, as well as the technical and organisational measures. An IT security white paper is available in two versions: a general version available to all users in the platform, and a confidential version for licensees after signing a non-disclosure agreement. On request, we also provide the certification evidence of our hosting and DMS partners.

Yes. Like all data, backups are stored in Germany. Regular backups protect the platform against data loss, and no data leaves the country in the process.

You can sign in to 5F via the login button in the header of this website or via the 5F App on your smartphone. If your organisation uses 5F White Label, you sign in at its own address instead, for example cloud.yourdomain.com. Invited participants receive their access with the invitation and confirm it once.

5F provides standardised export functions that allow authorised users to download documents and content individually or in bulk per workflow and save them locally. This applies throughout your use of 5F and at the end of the contract. You can also export the audit log for archiving.

Yes. If the administrator enforces two-factor authentication for the organisation, employees and external contacts go through the same second step when signing in. Users can choose between an SMS code and an authenticator app.

Data in transit between your browser and 5F is protected by TLS, at least version 1.2, and version 1.3 with stronger cipher suites where the browser supports it. Data at rest is encrypted with AES-256. If the security assessment of a method changes, 5F adjusts its configuration accordingly.

The first point of contact for invited participants is the firm or organisation through which they use 5F. That organisation knows how 5F is used in their case and can obtain further information directly from 5F if needed. This page answers general security questions; for anything else, you can reach 5F at sicherheit@5fsoftware.de.

On upload, 5F blocks file formats that can carry malicious code, such as executable files. Content is not automatically scanned for viruses on upload; when files are downloaded, the antivirus software in your own environment checks them as usual.
