SecureShare makes sharing files easy, flexible, and secure. Large files can be transferred effortlessly, without being constrained by traditional size limits or compromising on security. Thanks to end-to-end encryption, your data remains protected and is accessible only to the intended recipients.
As a self-hosted solution, SecureShare is designed specifically for enterprise customers. It runs on your infrastructure, giving you full control over your data. At the same time, the module integrates seamlessly with Threema Work and Threema OnPrem, offering a familiar and intuitive user experience.
With features such as centralized file management, external sharing links, and granular access rights, SecureShare is a reliable and scalable solution for secure file sharing in enterprises.
The conferencing feature enables secure, hassle-free meetings, even with external participants. Group calls can be started directly within the familiar messenger interface, while external participants can easily join via a link in their browser without needing to download the app.
All calls are end-to-end encrypted and accessible only to participants who have an invitation link. Since online meetings are initiated and conducted directly within Threema Work or Threema OnPrem, there is no need to switch to an additional tool with an unfamiliar interface.
With features such as a waiting room and moderator-controlled participant admission, the conferencing feature provides a secure and flexible solution for collaboration, both within the company and with external participants.
In day-to-day work, knowing whether someone is available is often crucial. However, many communication processes lack this transparency, leading to unnecessary waiting times, delayed responses, and inefficient workflows.
The availability status in Threema Work and Threema OnPrem solves this problem by displaying availability directly in the chat. Employees can easily set their status to “Unavailable” or “Busy”, or create a custom status to signal whether they are available or prefer not to be disturbed.
This makes team communication noticeably more efficient: colleagues can better judge the right time to reach out while respecting periods of focused work. The result is fewer interruptions, clearer expectations, and a more productive workday.

Available for Threema OnPrem and Threema Work
Companies often face the challenge of exchanging sensitive information securely, quickly, and easily with external contacts. Private messengers often seem to be the only solution, but they come with risks.
This is where EasyConnect comes in: The company creates an individual QR code and sends it to the external contact. The contact scans the code, opening a secure and confidential communication channel. No complicated registration or detours are necessary. This enables secure corporate communication seamlessly beyond the company’s own solution.

Whether you use public providers such as OpenAI or Anthropic, or your own solution running on Azure or AWS, AiBridge enables employees to use the company-approved AI securely – anytime and anywhere – without leaving their familiar messaging environment or relying on a VPN connection.
