Citadel: Secure instant messaging

In an increasingly connected world, the security of our communications has become a major concern. Whether for sensitive business conversations or personal exchanges, data protection and privacy are essential. The French government also recently announced that all ministries would have to stop using applications such as WhatsApp, Telegram or Signal in favor of sovereign solutions, to enforce secure exchanges. This is where Citadel Team comes in, offering a secure messaging solution designed to meet the ever-increasing demands for security and confidentiality. Citadel also aims to be interoperable with other secure messaging services.

Security and confidentiality at the heart of our solution 

Our platform relies on end-to-end encryption to secure all communications in chat rooms, private conversations, calls or file sharing. This feature ensures that only you and your counterpart have access to the content exchanged. This layer of security ensures the complete privacy of the data exchanged. 

In addition, we offer two-factor authentication for user accounts, adding an extra layer of security to prevent unauthorized access.

Citadel Team has been awarded the France Cybersecurity label. Ercom is aiming for basic qualification with ANSSI, demonstrating our commitment to meeting the highest security standards. In addition to two ongoing CSPN certifications for Android and iOS mobile applications, Citadel Team has passed an ANSSI PASSI audit for all services. 

Operated by Thales and hosted in France, Citadel Team ensures data sovereignty using infrastructures (datacenters) subjected to strict security regulations, creating a secure environment for stored information. We are compliant with the GDPR. None of your data is exploited or resold, and Citadel Team does not display any advertising.

Simplified management for companies and government organizations 

Some instant messaging tools pride themselves on having no personal data about their users, not even their email address. In this case, organizations are unable to manage access to their tools, data, user revocation, etc. Citadel Team has chosen to address the needs of professionals, enabling simple, secure and efficient user management while ensuring absolute confidentiality of exchanges and security of business data. 

A dedicated server and a management console facilitate fleet management, reinforcing control and security of the environment. The administrator can terminate the account of any user leaving the organization. In this case, the user will be automatically removed from all groups, contrary to what happens on all discussion groups based on non-professional messaging applications.

Not just a robust messaging solution

Citadel Team is not just an instant messaging application, it's a complete platform that ensures end-to-end security for your communications: messages, calls, audio and video conferencing with screen sharing. Its user-friendly interface makes the transition to secure messaging seamless, offering an intuitive user experience without compromising security.

The interface is also cross-platform to facilitate the user experience, and users can register by themselves. Accessibility from a variety of devices, including smartphones, tablets, PCs and MACs, makes for a flexible use. This ease of access translates into a consistent, high-performance experience, making Citadel Team a strategic choice for those seeking an efficient and flexible collaboration and instant messaging solution. This unique solution on the market also promotes connection between organizations, facilitating collaboration through the seamless exchange of information within a trusted community.
