FAQs

Threema OnPrem is designed for companies looking for a self-hosted messaging service that provides total data ownership and the highest possible level of security and confidentiality (e.g., public authorities, industrial companies, police forces).

Threema OnPrem is typically recommended for a volume of 500 or more end-user licenses. To run and maintain a Threema OnPrem server, your company must be ready to invest in infrastructure, and technical know-how is, of course, an essential prerequisite. The needs of companies that don’t meet these requirements are covered by the SaaS solution Threema Work.

No. Although Threema OnPrem includes certain customization options (like integrating a logo into the app’s UI), white labeling as such is not supported.

Like Threema Work, Threema OnPrem comes with the annual price for the total amount of end-user licenses; add to that the one-time setup fee plus a yearly flat fee to cover server license, software updates, and technical support. To get a quote, please contact us.

Threema OnPrem is the self-hosted version of the SaaS solution Threema Work. When using Threema OnPrem, all data is stored on your company’s server, which translates to complete data ownership and total and exclusive control over every aspect of the communication tool. The app, the administration console, and the feature set of Threema OnPrem and Threema Work are, in essence, identical.

Threema OnPrem requires a Linux server (physical or virtual) with Docker. For smaller deployments of up to 1,000 users, 4 CPU cores, 8 GB RAM, and about 100 GB disk space are sufficient. Larger deployments of up to 100,000 users require 8 more CPU cores, 32 GB of additional RAM, and about 1 TB of disk space. These numbers are highly dependent on the usage intensity.

Threema OnPrem is an independent and completely self-contained chat environment. Users of Threema OnPrem can only communicate with other users of the same OnPrem instance. Using the Threema OnPrem app, it is therefore not possible to communicate with users of the Threema or the Threema Work app.

However, Threema, Threema Work, and Threema OnPrem can be used in parallel on the same device (but different Threema IDs have to be used).

Threema OnPrem: Threema Work on Your Own Server

Threema OnPrem offers the same range of features and the same convenience as Threema Work, the well-established secure messaging solution for organizations. Both the app and the administration console of Threema OnPrem and Threema Work are, in essence, the same. For details about the app and the dashboard, please refer to the technical documentation of Threema Work.
