Digital sovereignty is possible - with open source
Email and collaboration are essential digital infrastructure for governments and regulated organizations.
Many organizations have become deeply dependent on foreign cloud providers for these mission-critical functions. These dependencies introduce new risks due to changing geopolitical, trade, and regulatory landscapes.
Digital sovereignty is not about isolation or rejecting global cooperation. It is about retaining control and independence over essential systems.
Built for public-sector workflows
Public institutions and regulated organizations face elevated risk requirements that demand high levels of predictability, auditability, and resilience.
OX App Suite addresses these needs by being most commonly deployed on-premise, enabling organisations to maintain maximum control over their infrastructure, data, and operations while still offering cloud deployment where appropriate, resulting in a secure, controlled, and dependable collaboration environment.
OX App Suite supports common public sector workflows out of the box:
Delegation and substitution
On-behalf management allows users to delegate email and calendar access.
Functional and shared mailboxes
Support for shared mailboxes (e.g. info@, service@) enables centralized communication without the need of email forwarding.
Secure communication of sensitive information
OX Guard enables easy, user-friendly email and file encryption using PGP or S/MIME.
Usability without loss of control
A familiar and intuitive interface provides a consistent experience across desktop and mobile, ensuring productivity from day one.
Optional AI assistance under organisational control
OX AI can generate well-written emails, suggest replies, and summarise incoming messages, offered as an option and governed by clear policies.
More solutions for the digital workplace
Email and calendar are the backbone of public sector communication. Many organizations also require additional productivity and collaboration tools, such as secure file sharing or video conferencing.
OX follows a platform strategy that integrates best-of-breed, complementary solutions, delivering flexibility, avoiding new lock-ins, and enabling real digital sovereignty instead of replacing one dependency with another.
A Sovereign digital workplace: openDesk
For organizations seeking a comprehensive digital workplace, openDesk delivers an integrated office and collaboration suite built specifically for public sector organizations.
openDesk is a secure platform that combines essential tools.
openDesk is developed and offered by ZenDiS (Zentrum für Digitale Souveränität der Öffentlichen Verwaltung), a public-sector organization established by the German Federal Government to support digital autonomy across Bund, Länder, and Kommunen.
openDesk does not require a tender where sovereign digital infrastructure is mandated, simplifying procurement and adoption for public authorities.
With openDesk, organizations gain a modular, open-source workplace built around open standards and interoperable components, enabling flexible deployment without introducing new vendor lock-in after moving away from hyperscaler ecosystems.
