# A major step forward for the City of Nanterre

The City of Nanterre takes a decisive step towards digital sovereignty with GoFAST

The **City of Nanterre** has distinguished itself by becoming the first local authority in France to migrate from **Microsoft Teams** to **GoFAST**, an **open source,** **sovereign** collaborative solution developed by CEO-Vision SAS.

This successful transition marks a turning point in the **management of digital tools** for **French local authorities.** GoFAST, an alternative to American solutions such as **Microsoft SharePoint** and **Teams**, offers a response adapted to today's challenges: **increased efficiency,** **digital sovereignty** and **infrastructure modernization,** **replacing traditional file servers.**

After a year in use, the results are clear to see: **optimized collaboration,** significant **efficiency gains** and enhanced **control over sensitive data.** This emblematic project reflects the growing **needs** of **French administrations.**

This breakthrough confirms that there are competitive **European (and French) alternatives** to the international giants, better suited to the needs of local authorities.
