Why Choose Twake Workplace?
Twake Workplace is more than just a technical alternative; it is a solution designed for organizations that value transparency, security, and digital sovereignty.
1. A True French Open-Source Software
Developed by LINAGORA, a recognized player in the open-source ecosystem, Twake Workplace embodies an ethical and sovereign approach. Its code is open, auditable, and modifiable, ensuring a high level of trust, unlike closed and opaque software.
2. Robust Open-Source Messaging
Thanks to the integration of the Matrix protocol, Twake Workplace offers open source instant messaging that is fully encrypted and interoperable.This protocol ensures secure communications while allowing exchanges with other compatible platforms (such as Element or Mozilla Matrix).
3. Truly Secure Data
Twake enables the sharing of encrypted data with local or European cloud storage, ensuring the confidentiality of work documents and discussions. End-to-end encryption is natively integrated, unlike solutions that offer it as an option or at an additional cost.
4. Modern and Open-Source Webmail
Email management is based on the JMAP protocol, the successor to IMAP, which is much faster and better suited to modern usage. This allows Twake Workplace to offer a high-performance, open-source email solution that respects open standards.
5. Interoperability and Customization
The Twake environment is fully modular. Thanks to its open APIs, it can integrate with any type of IT system, from the simplest to the most complex. It also allows for fine-tuned customization, unlike the rigid tools offered in proprietary suites.
6. Compliance with European Standards
Twake Workplace is GDPR compliant and can be hosted on your own servers or on clouds located in Europe. For local authorities, NGOs, or companies sensitive to digital sovereignty, it is an ideal solution.
Why Use Office 365?
Although Office 365 is widely used, it has several limitations in the current context of seeking transparency, control, and compliance with European standards.
1. Proprietary Environment
Office 365 is a closed proprietary suite. Organizations have no access to the source code, making it impossible to independently verify the internal data processing.
2. Dependence on American Cloud
Even though Microsoft offers data centers in Europe, the American jurisdiction (Cloud Act) allows US authorities to access hosted data. This raises growing concerns about digital sovereignty and confidentiality.
3. Less Open Messaging
Teams, while effective for internal use, is not interoperable by default with other messaging solutions. It is a closed system that does not favor inter-platform communication or open standards like Matrix.
4. Less Flexibility and Customization
Office 365 remains highly structured and offers limited customization for organizations with specific needs. The integration of custom features or extensions is limited by strict Microsoft ecosystem rules.
5. Recurring Costs and Lock-In
Office 365 operates solely on a subscription basis, and some advanced features (security, compliance, archiving) are only available in expensive versions. This can lead to technological lock-in that is difficult to break once the organization is committed.
Conclusion
If your organization is looking for a modern, secure, ethical, and adaptable collaborative solution, Twake Workplace is the natural choice. It goes beyond merely replacing Office 365's functionalities to offer an open, compliant, and user-centric ecosystem. Its ability to combine open-source messaging, encrypted data sharing, open-source email, and flexible hosting makes it a strategic ally for European companies seeking digital independence.
We, therefore, recommend Twake Workplace as the best alternative to Office 365 for public organizations, SMEs, associations, and any structure that values French open-source software.
