What is 5F and what is it used for?2026-02-23T19:39:15+01:00

5F is a cloud platform for secure data exchange and structured collaboration. Content, communication, and tasks are bundled in digital data rooms and checklists, enabling teams and external parties to work efficiently in a shared context.

Who is 5F for?2026-02-23T19:39:11+01:00

5F is suitable for organizations that regularly exchange extensive documents and information with multiple parties, prioritizing confidentiality and clear processes. The platform was developed to meet the requirements of professionals with confidentiality obligations and is applicable across industries, such as in firms (Tax Consulting, Auditing, Legal Consulting, notarial services), Companies, and associations.

How does 5F protect confidential data?2026-02-23T19:39:04+01:00

5F was specifically developed for professionals bound by confidentiality and meets the highest data protection and data security standards. Data is stored in ISO-certified German data centers, and operations are consistently geared towards data sovereignty, ensuring that your data does not leave Germany. Further details on security measures and hosting can be found here.

Which typical use cases does 5F cover?2026-02-23T19:38:57+01:00

With 5F, you can request documents and information in a targeted manner via checklists and collect them in a structured way. For secure exchange and collaboration, you use data rooms where all content comes together in the appropriate context. Tasks and processing statuses clarify responsibilities and make progress transparent.

Requirements vary depending on the firm or company. 5F can be flexibly adapted to your processes and therefore covers many use cases. We would be pleased to show you in a consultation how 5F can be used most effectively for your needs.

Which problems does 5F solve in the daily routine of firms and companies?2026-02-23T19:39:11+01:00

5F brings structure to collaboration and reduces follow-up questions, email ping-pong, and media disruptions. Responsibilities can be clearly assigned, progress can be tracked, and important changes can be identified centrally. This saves time and provides a better overview of daily business operations.

How does 5F differ from email, cloud storage, and file sharing?2026-02-23T19:39:00+01:00

With email, cloud storage, and file sharing, files and agreements are often scattered across multiple locations. This quickly leads to queries, unclear versions, and a lack of overview. For confidential documents, email is also often not a suitable channel.

5F combines data exchange and communication on a single platform, keeping everything in one place. Documents can be specifically requested, responsibilities and processing statuses remain transparent, and coordination occurs directly within the content. Collaboration takes place in an environment designed for sensitive data.

How quickly can I get started with 5F?2026-02-23T19:38:52+01:00

Typically, you can get started very quickly: In a brief online introduction (approximately 45 minutes), we will show you the most important processes and answer your questions. We will then set up 5F for you—usually within 1–2 business days. After that, you can start right away (optionally beginning with the 14-day trial period).
