Leaving Microsoft 365: meet us at Open Source Experience 2026

We are delighted to announce that we will be taking part in Open Source Experience on 9 and 10 December, at STAND C26, Paris Expo Porte de Versailles (Hall 5.2), Paris.

A must-attend event for the European open source ecosystem, the show brings together decision-makers, CIOs, CISOs and free software players every year to discuss the key challenges of open and sovereign digital technology.

Faced with technological dependencies and extraterritorial laws such as the Cloud Act, more and more public and private organisations are looking to regain control over their data and collaboration tools. This is exactly what GoFAST, the sovereign, open-source alternative to Microsoft 365 (SharePoint, Teams, Office, Outlook and Exchange), delivers.

A workshop led by Christopher Potter

On 20 October 2026, from 3:00 pm to 3:20 pm, Christopher Potter, Founder and President of CEO-Vision, will lead a workshop on: "How to leave Microsoft 365, cut your costs and secure your data with a sovereign collaborative document management platform"

Rising licence costs, dependence on a single vendor, exposure of data to extraterritorial laws: leaving Microsoft 365 is possible, provided you rely on the right decision criteria. Christopher Potter will show how GoFAST helps reduce costs, with no usage fees tied to a proprietary vendor, and secure sensitive data through document classification and fine-grained rights management.

Workshop agenda:

• GoFAST 4.6: the new version and its main improvements.
• GoFAST Protect: a backup environment hosted in Europe to ensure business continuity in the event of a major incident or cyberattack.
• Built-in sovereign AI: powered by Mistral AI, it assists users without their data ever leaving the controlled perimeter.

These topics will be illustrated with a live demo and customer case studies.

Come and meet our teams at our stand

• A complete, sovereign collaboration platform: Alfresco-based document management, document co-editing, approval workflows, video conferencing, chat and email, sovereign AI with Mistral AI, hosted On-Premise or as dedicated SaaS on SecNumCloud-qualified infrastructure.
• Control over your data and your budgets: document classification, GDPR and NIS 2 compliance, full reversibility thanks to open standards, with no dependence on a proprietary ecosystem.
• Organisations that have made the move: the City of Nanterre (1,700 staff moved off Teams and SharePoint in less than a month) and the Haute-Savoie Departmental Council (3,000 users, over one million documents migrated) show that a well-managed transition is possible, with no disruption for users.

Whether you are planning to leave SharePoint, Teams or the entire Microsoft suite, come and discover how GoFAST supports your transition to a sovereign, future-proof platform.
