Open Source: The Key to Europe’s Strategic Autonomy

Open Source Experience is the largest professional open source event in Europe, bringing together the stakeholders who are shaping the digital future.

📅 On the agenda: two days of case studies, workshops, round tables, and 130 conferences exploring the technological, strategic, and societal challenges of open digital innovation.

More than 90 exhibitors, 4,000 professionals, and 150 speakers are expected. This edition will tackle an ambitious theme: “Open Source, the Key to Europe’s Strategic Autonomy.”

Sovereignty, cybersecurity, data governance… Technology plays a central role in our daily lives, our economy, and our security. 2025 marks a decisive moment in Europe’s journey toward greater digital independence.

For eXo Platform, the event is the opportunity to:

  • meet our users and partners,
  • connect with public and private decision-makers,
  • show our latest innovations,
  • and above all, demonstrate that it is possible to build a complete, high-performing, open, and sovereign digital workplace, free from GAFAM dependency.

Veronika Mazour Mestrallet Leads the Track on Collaborative Tools

A major highlight this year: Veronika Mazour Mestrallet, CEO of eXo Platform, will lead one of the seven tracks selected by the 2025 program committee.

This recognition reflects both eXo’s expertise and long-standing commitment to open source, as well as its role in the French and European open source ecosystem.

Together with experts, decision-makers, and contributors, Veronika will facilitate discussions on the theme: “Collaborative Tools and Business Applications: Regaining Digital Autonomy.”

A Must-Attend Talk: How to Replace Microsoft 365

Among the leading talks, don’t miss our conference on December 10 at 4 :20 p.m. dedicated to public and private organizations looking for alternatives to GAFAM proprietary solutions:

Replacing Microsoft 365 with a unified Open Source digital workplace powered by eXo Platform

📅 Wednesday, December 10, 2025 – from 4:20 p.m. to 4:40 p.m. – Room 3

Today, many French organizations still choose Microsoft 365 by default or due to a lack of awareness of alternatives. Yet, this dependency raises significant issues:

  • Sovereignty and strategic autonomy
  • Data security and confidentiality
  • Cost control and information system evolution

In this session, Veronika Mazour Mestrallet will explain how to regain control of your collaborative environment with eXo Platform, a full-featured and sovereign open source solution.

The program includes:

  • Migration success stories: Occitanie Region, the cities of Lunel, Clichy-sous-Bois, Chelles…
  • Comprehensive functional coverage: collaboration, communication, document management, email integration, and more
  • A unified user experience through a service portal and seamless integration of business applications (GLPI, iXBus, etc.) to drive adoption

This hands-on workshop is aimed at CIOs, digital transformation leaders, public and private decision-makers, and any organization seeking to combine independence, security, efficiency, and sovereignty.

Meet our team

Beyond the conference, you’ll find the eXo Platform team at our booth throughout the event.

Live demos of our sovereign open source digital workplace eXo, discussions about your projects and challenges, sharing of best practices… This is the perfect opportunity to build your future collaborative workplace together.

Whether you’re still in the strategic planning phase or already engaged in a digital transformation project, we’ll be delighted to meet you.

I am the communication manager at eXo Platform. I found myself in communications a bit by chance, but this field brings together everything that pationates me: creativity, energy, meetings, collaborative work, sharing and exchanges of good practices. I need to give meaning to what I do and put people at the center of all my actions.
