Hexagone suite - 2026 Pricing, Features, Reviews & Alternatives

Hexagone is the collaborative and office suite published by Interstis Solutions, designed as a sovereign French alternative to Microsoft 365 and Google Workspace.

What's in the suite

Business email, shared calendars and organisation directory. File storage with real-time co-editing of documents, spreadsheets and presentations. Instant messaging, video conferencing and VoIP telephony. Project spaces with task tracking and workflows. Workstation security, including account management, patch management and Active Directory integration.

The suite is modular. Deploy all of it, or start with a single brick and extend as your existing contracts expire. Everything comes from one publisher, with one set of credentials and one support contact.

Where your data lives

All data is hosted in France on SecNumCloud-qualified infrastructure and remains under French and European jurisdiction. Hexagone is not exposed to extraterritorial legislation such as the US Cloud Act, and no personal data leaves the European Union, which simplifies your GDPR records of processing. Granular permissions apply to every space, folder and document, so internal teams, field agents and external partners can work in the same environment without over-sharing.

Who uses Hexagone

Local authorities: shared workspaces across town halls, technical services and satellite sites, with secure document circulation for council meetings and inter-municipal projects.

Government agencies: collaboration between central and regional offices, with data that never leaves national jurisdiction.

Healthcare and social care: coordination across sites and with external partners under strict confidentiality requirements.

Education: shared drives, video sessions and messaging for staff and students.

Private companies: multi-site teams, remote workers and subcontractors working on shared projects, particularly in regulated industries.

Why organisations switch

Hexagone is typically around 30% less expensive than equivalent US suites, priced in euros, with no tier upgrades required to unlock security or compliance features. Migration from Microsoft 365 or Google Workspace covers data transfer, user training and change management, and support is delivered in French by teams based in France.

Hexagone is built on French technology by a consortium of seven French software companies led by Interstis Solutions, a laureate of the France 2030 programme. More than 800,000 users collaborate on the platform today, from small municipalities to national institutions.
