How to get Carbonio for your organization
Carbonio is delivered exclusively through a network of certified partners trained to deploy, migrate, and support sovereign email and collaboration — in your country, your sector, and the operating model your organization requires.
Why partner-led
A delivery model designed for accountability, not resale
Sovereign collaboration takes more than just software. It requires local partners with real expertise and a vested interest in your success.
Local accountability.
A certified partner in your country, your language, your timezone, and your compliance context. One delivery relationship for migration, deployment, support, and managed services — not a distant vendor's ticket queue.
Sovereign deployment.
On-premises, private cloud, or sovereign SaaS — always within your jurisdiction, never tied to hyperscalers. Your data stays on infrastructure you control, in the regions you choose.
Certified expertise, vendor-backed.
Every partner is trained, certified, and audited to consistent technical and operational standards. When product-level expertise is needed, your partner escalates directly to Zextras — no opaque support queue in between.
Deployment models
Three ways to run Carbonio
Pick the model that fits your legal, security, and operational requirements. Same components, same admin panel, same migration path between models if you change later.
On-premises.
Full control, your hardware, your data center. Right for organizations with existing infrastructure investments, strict residency mandates, or air-gapped environments.
Private cloud.
Hosted in a data center you choose — sovereign, EU-based, or jurisdiction-specific. Right for organizations that want a cloud operating model without giving up control over residency.
Sovereign SaaS.
Delivered as a managed service by a certified partner under EU operating control. Right for organizations that want SaaS convenience without hyperscaler legal exposure.

Where Carbonio fits
Where Carbonio delivers the most value
Sectors where data sovereignty, regulatory alignment, operational flexibility, and trusted delivery matter most — and where the certified-partner model has the strongest fit.
Public Sector
Digital sovereignty in practice.
Public administrations, ministries, municipalities, universities, and agencies that need jurisdiction-aware deployment, NIS2-ready governance, and procurement clarity through local providers.
Financial Services
Auditable sovereignty for regulated finance.
Banks, insurers, and financial institutions with DORA, BaFin, and EU financial supervisor obligations — data residency, audit trails, retention, and recovery on infrastructure they control.
Healthcare
Privacy without sacrificing usability.
Hospitals, clinics, laboratories, and healthcare networks that need stronger privacy controls, role-based access, and deployment choices aligned with local health-data standards (HIPAA, NEN 7510, national equivalents).
Education
One environment for staff, faculty, and students.
Schools and universities consolidating fragmented mail, chat, files, and meetings — simpler at scale, easier to administer, and aligned with regional data-residency expectations for student data.
Control and Privacy-Focused Organizations
Made for digital sovereignty.
Organizations in need of privacy and control over data and infrastructure dictated by data privacy regulations and regional compliance like the GDPR, DPDP, etc.
Cloud & SaaS Providers
Sovereign collaboration in your stack.
Cloud and SaaS providers building sovereign offerings for European, regulated, or sector-specific markets — Carbonio as the collaboration layer inside your platform, deployed and supported under your brand.

FAQ
Common questions about getting Carbonio
How do I purchase Carbonio?
Carbonio is sold and delivered exclusively through certified partners — system integrators, MSPs, hosters, telcos, and cloud providers trained on the platform. Share your country, sector, and project scope via the Find a Provider request, and Zextras routes it to a certified provider who reaches out to scope licensing, deployment, and support.
How much does Carbonio cost?
Pricing depends on edition (Email or Workspace), user count, deployment model (on-premises, private cloud, sovereign SaaS), and the services package agreed with your certified partner. Three things typically shape the math in Carbonio's favor: (1) a unified platform replaces 3-5 separate subscriptions (mail, chat, meetings, files, backup), (2) self-hosted and private-cloud deployments avoid public-cloud per-user markup, (3) built-in capabilities (real-time backup, antivirus, antispam, HSM) eliminate third-party tools and extra-cost add-ons like Microsoft EOP or Google Vault. Organizations replacing a Microsoft 365 or Zoho bundle commonly see meaningful TCO reduction — your partner can build a precise comparison for your specific setup.
Can I download or trial Carbonio directly?
Carbonio is delivered through certified partners. Trials, proofs of concept, and demo environments are arranged with a partner, so your evaluation runs in a real deployment context rather than an isolated sandbox.
Why is Carbonio sold only through partners?
Sovereign collaboration is a delivery problem, not just a software problem. Certified partners bring local accountability, sector expertise, migration know-how, and the operational support that regulated and security-sensitive deployments require. Zextras stays focused on the platform; partners stay focused on customer outcomes — with vendor-backed escalation when product expertise is needed.
Can I migrate from Microsoft 365, Google Workspace, Exchange, Zimbra, Open-Xchange or Zoho?
Yes. Certified partners deliver migrations from all major platforms such as Microsoft 365, Google Workspace, Exchange (Server and Online), Zimbra, Open-Xchange, and Zoho. Mail, calendars, and contacts move across; the exact fidelity depends on what each source platform exposes, which the partner confirms during scoping.
What does a typical Carbonio project look like?
Three phases: (1) discovery and scoping with the partner — sector requirements, deployment target, migration source, user count; (2) deployment and migration — with coexistence periods, phased rollouts, and weekend cutovers as standard; (3) ongoing managed service and support — with SLA, monitoring, and escalation paths back to Zextras for product-level issues.
Can I switch deployment models later?
Yes. On-premises, private cloud, and sovereign SaaS use the same components and the same admin panel, so you can move between models later — for example, on-premises to private cloud — without re-platforming. Your certified partner plans the transition.
