Instant messaging has become an integral part of everyday business communication. It’s hard to imagine companies not using chat apps for both internal and external communication. However, as far as the legal grounds for the corporate use of messaging services are concerned, the situation in the EU is tricky. Since almost always personal data is involved, non-compliance with the legal requirements can have drastic consequences.

To shed some light on the matter, we commissioned the renowned FZI Research Center for Information Technology in Karlsruhe, Germany, to conduct a legal study focusing on the situation in the EU and in Germany in particular. The result is a comprehensive report in which the experts thoroughly examine the legal aspects of using chat apps for professional purposes. Based on the final report, the authors have also created a practical guide that helps companies to choose the right messaging service.

The 300-page report as well as the compact guide, both written in German, are publicly available (“open access”). The documents fully represent the authors’ views; Threema didn’t have any influence on the content (cf. press release FZI (German)).

“In our study, we highlight the legal situation for the corporate use of messenger services in order to bring clarity into this complex area and present the legal obligations by means of simple checklists,” says Dr. Manuela Wagner, head of the study.

“We deliberately don’t make recommendations for specific service providers in the study. We weren’t able to examine them in detail since the possible use cases are far too complex,” she adds. “However, one of the conclusions that can be drawn from our work is this: As far as the corporate context in the European Union is concerned, various instant messengers, especially ones developed for personal use, hardly, if at all, meet the relevant legal requirements for data protection or for the protection of trade secrets.”

Online Event “New Working World”: Our Talk on Shadow IT

Chat on the Computer Without a Browser

Threema Web, which has been around for some time, allows you to conveniently use Threema Work from the desktop without compromising security. Now, chatting on the computer gets even more user-friendly.

Thanks to the new desktop app, you no longer need to search for Threema Work in the browser and switch back and forth between tabs all the time. Instead, your business messenger is always at hand in the dock or via the app switcher. Anyone who regularly exchanges text messages on a computer will greatly appreciate this streamlined chatting experience.

The desktop solution is available for macOS, Windows, and Linux starting today. Just like the web client, on which it is based, the desktop app establishes an end-to-end encrypted connection to your mobile device. Of course, Threema Work for desktop covers the complete range of Threema Web’s features.

In terms of security, the desktop client even surpasses the high standard of the tried-and-tested web solution in certain respects. For one thing, there’s no way for browser plugins to introduce vulnerabilities. For another, it would be even more difficult for attackers to manipulate the app code since it isn’t loaded from a server each session but permanently stored on the user’s end.

Outlook: Threema Work 2.0 for Desktop

The next major update of the desktop app will not only introduce a completely redesigned user interface, it will also be based on a totally new architecture. Thanks to multi-device functionality, version 2.0 no longer requires an active connection to your mobile device. This is to say that you’ll be able to use the desktop app even if your smartphone happens to be turned off.

The development of the multi-device technology is in full swing, but it turns out to be more time-consuming than anticipated. Several technical challenges have already been met, but there is still work ahead. More often than not, the path to security is neither easy nor fast. And when it comes to security and privacy protection, we are under no circumstances willing to cut corners. Unfortunately, the multi-device solution’s release therefore gets delayed. Thank you for your patience and understanding!

We’ll keep you posted and provide another update about the development of Threema Work 2.0 for desktop at the end of the year. Stay tuned!

Update 2022-12-07: There’s a tech preview of Threema 2.0 for desktop available, which allows iOS users to test the upcoming multi-device functionality ahead of time.

Threema Work and Healthcare – A Perfect Match

There’s hardly a business sector where Threema Work isn’t widely adopted. IT service providers, political parties, and educational institutions rely on Threema Work, just like renowned companies in retail, the hotel business, and in the automotive industry use Threema’s business solution (see Success Stories).

Threema Work is the perfect fit wherever corporate communication has to be fast, straightforward, and secure. In one industry, these requirements apply to particularly high degree: healthcare.

Besides a fast response time and general reliability, data protection and security are crucial factors in medical communication. After all, patient data is inherently personal, and it often contains highly sensitive information. When exchanging such data, strict compliance with data-protection standards is imperative.

With its consistent focus on security and data protection, Threema Work is perfectly suited for professional use in the healthcare sector. It enables organizations such as hospitals, medical practices, clinics, and pharmacies to take full advantage of the many benefits instant messaging provides – without sacrificing data privacy in the process.

Messengers and Shadow IT: The Risks

The term “shadow IT” refers to software and hardware used by employees without their company’s knowledge or approval.

One reason for the rise of shadow IT is the increasing number of cloud services, “software as a service” solutions, and messenger apps targeted at consumers. Employees have a plethora of easy-to-use options at their fingertips, and they already know how to use many of them from personal experience. If a process doesn’t run smoothly and no assistance from the IT department is available, employees are tempted to address the problem by resorting to their own tools.
