X-ROAD INSIGHTS · ANALYSIS

The private sector uses X-Road mainly for one thing: pulling government data.

553 private firms exchange data over X-Road — but almost exclusively with the state. Genuine business-to-business (B2B) is negligible. Here: which data most often, with whom and for which use cases.

With whom? Almost only the state

Classifying the other side of each query, 97.2 % of all private-sector calls go to government registers. Private-to-private (B2B) is only 0.6 % — for business, X-Road is essentially a gateway to state data, not a B2B marketplace.

Definition of “private sector”: members with a company registration (code 1…). Deliberately excluded are legally private but functionally public actors — public hospitals, the public-transport host, bailiffs and state-adjacent IT centres. Class ~92 % authoritative, the rest via the registration-code scheme. Telia's large calls stem from hosted third-party services (Security-Server-as-a-Service), not its core telecom business.
