In a constantly evolving professional environment, **instant messaging** and **video conferencing** tools are essential to team performance. Remote work, multi-site organizations, and the need for responsiveness require employees to **communicate easily and securely**.

Faced with solutions such as **Microsoft Teams**, **Zoom**, and **Google Meet**, many companies are now looking for a **sovereign** and **centralized alternative**. **GoFAST** addresses these challenges by offering a **complete collaborative platform** that combines **chat**, **video conferencing**, and **document management** in a unified environment, with secure hosting options tailored to organizational needs.

## GoFAST: a centralized collaborative DMS solution

**GoFAST** is not just a chat or video conferencing tool: it is a **complete collaborative document management system (DMS)** that centralizes **all information and workflows** on a single platform.

The solution includes:

- **Secure enterprise chat (Element)** and **video conferencing (Jitsi Meet)**
- **Document management** from creation to **electronic signature**
- [**Workflow**](https://www.ceo-vision.com/en/content/workflows-gofast) **and process automation**
- **Task management with** [**Kanban**](https://www.ceo-vision.com/en/content/discover-kanban-feature-gofast)
- [**Email**](https://www.ceo-vision.com/en/content/gofast-mail-collaborative-and-sovereign-messaging) **(coming soon)**

![](/sites/default/files/inline-images/Banni%C3%A8re%20site%20-web%20NEWS%2816%29_1.png)This centralization makes GoFAST **a credible alternative to solutions such as Teams, Zoom, and Google Meet...**, and more broadly to Microsoft 365, file servers, and outdated DMS solutions.

With GoFAST, everything is **centralized** on a **single platform**: teams can quickly find information, move **easily** from one feature to another, and collaborate in a more **fluid** and **productive** way.

## Security and digital sovereignty

GoFAST stands out for its **sovereign and secure approach**, allowing companies to centralize their communications while maintaining full **control** over their **data**. The platform can be deployed according to needs:

- **Secure SaaS (SecNumCloud)**: hosting in a secure French cloud compliant with regulations
- **On-Premise**: on-site deployment for full infrastructure control

All communications, whether chat messages or video meetings, are protected by **end-to-end encryption**, ensuring the **confidentiality of sensitive information** and **GDPR compliance**.

## Chat with Element and video conferencing with Jitsi Meet: essential building blocks

Integrated into GoFAST, chat with Element and video conferencing with Jitsi Meet are the two pillars of remote communication.

### Chat with Element

- **Secure** instant messaging, **one-to-one** or in **groups**
- File and document sharing
- Full **conversation history** and **advanced search**
- **Customizable notifications**
- Enables **centralization of all professional discussions** and reduces fragmentation

- **Video meetings** in one click **from the chat**
- **Screen sharing, collaborative whiteboard, customizable backgrounds**
- **Breakout rooms** and **session recording**
- **Built-in chat** during meetings for questions and real-time interaction
- Ensures **efficient real-time collaboration**, even remotely

These two components are **strategic for productivity and communication continuity**, as they allow **all interactions to remain within the same platform**, instead of multiplying tools. They also make it easy to **switch from chat to video conferencing**: a quick message can turn into a meeting in seconds, without changing tools.

Although these tools are popular, they have certain limitations:

- **Too many** applications and interfaces
- **Scattered communications** and time loss
- **Difficulty** in centralizing conversations and documents
- **Security and confidentiality risks**

Companies are now favoring **unified communication solutions** that combine **chat, meetings, and document management** within a **single collaborative workspace**, reducing information loss and optimizing working time.
