Maintain a Healthy Work–Life Balance with Threema Work

In times of home office and constant availability, it is increasingly difficult to protect one’s spare time against the intrusion of work. Thanks to the new off-hours policy in Threema Work for Android, there is now an efficient way to restore a healthy work–life balance.

Simply define your working hours in “Settings > Sound & Notifications > Do not disturb,” and you won’t be bothered with work issues after office hours. If your colleague from accounting calls while you’re off duty, the call will automatically be rejected. If the overzealous marketing manager sends text messages on the weekend, you won't notice because you don’t receive any notifications. Instead, you’ll spend your leisure time relaxed and free of work-related worries. And after your uninterrupted downtime, you’ll be even more productive when you start work rested and recharged on Monday morning.

Bosch uses Threema Work for mobile communication

More and more companies start to realize that employees would like to communicate with colleagues the way they are used to communicate with friends, i.e., using messaging apps. However, conventional chat services don’t meet the corporate requirements for data protection, security, and administration capabilities. If no alternative is put in place, employees will eventually resort to apps they use in their personal lives. As a result, a parallel IT emerges, and there is no strict separation between personal and professional communication.

This is where Threema Work comes in. The professional messaging solution for companies is tailored to the needs of organizations (central user management, pre-configuration of the app, full legal compliance, etc.) and provides the level of convenience users are accustomed to from similar consumer apps.

Numerous renowned companies rely on Threema Work for secure and efficient team communication. They are now joined by Bosch, a leading international technology company and service provider.

Last Threema update for Windows Phone

An era comes to an end. Due to the discontinuation of Windows Phone (and Windows 10 Mobile), there will be no further Threema updates for this platform.

In its last update (to version 3.0), the Windows Phone app adds support for Threema Safe. This allows Windows Phone users to transfer their Threema ID, contacts, and groups to another platform and use Threema on Android or iOS in the future.

New Threema audit

Threema is known for rock-solid security and unparalleled privacy protection. The algorithms and protocols used in Threema’s cryptography are well documented, and the encryption’s proper implementation can be verified at any time. On top of that, renowned experts periodically conduct independent audits to confirm Threema’s security.

Headed by Prof. Sebastian Schinzel, the Lab for IT Security of Münster’s University of Applied Sciences has thoroughly audited Threema’s code during the past months. With considerable effort and all the required technical expertise, the Android and the iOS app as well as Threema Safe were examined in great detail for possible security flaws. However, no critical vulnerabilities were found, and the researches gave Threema top grades:

  • “Threema takes the security and privacy of their users very seriously.”
  • “Threema performs as specified in the published documentation.”
  • “Threema’s security and privacy features are intact and effective.”

The audit report is publicly available in its entirety. The few minor issues that were put forward have been addressed immediately and are already fixed in the current app versions. Get an idea of the test procedure Threema has undergone:
