Multi-Tenancy: Threema Work Is the Messenger for All Departments

The city of Frankfurt am Main has been using Threema Work since 2019, and the number of users has been steadily increasing ever since. In August 2021, more than 33 offices and about 1,600 employees were using Threema Work.
Multi-tenancy was a prerequisite because the individual offices have to be in charge as far as administration and user management is concerned (app pre-configuration, etc.). The central IT office, however, is only responsible for basic setup and purchase.

Use Cases

  • Threema Work is used in the following areas and offices: central IT office, education, fire department, public health office, city drainage, road construction department, public order office, landscape department
  • In particular, employees who are often on the go, or ones who do not have a conventional office workspace, use Threema Work as preferred communication channel.
  • The main goal is to offer the staff an adequate WhatsApp alternative in order to avoid dangerous shadow IT in the form of chat services that lack proper security and privacy protection.
“Threema Work clearly offers the best bang for your buck.”
