Data transfers

On this page, you will find instructions on how to securely submit the extracted data or your own files to Findata, or how to request a data transfer from Findata. Data transfers are carried out through a secure transfer service, either via Tunneli (formerly known as Nextcloud) or Supertunneli.

We request the materials from the controllers primarily in CSV format and deliver them to clients in CSV format (semicolon as separator, UTF-8 encoding).

Our data transfer services are being renewed throughout spring 2025. Read more.

Service descriptions for Tunneli and Supertunneli

Tunneli

Tunneli is a secure transfer service accessible via a web browser. It enables the encrypted delivery of personal data files to and from Findata.

Tunneli Setup Guide

Tunneli is used via a web browser. To use the service, you need user credentials, which can be requested through Findata’s e-service at asiointi.findata.fi.

If you already have Nextcloud credentials ordered through Findata, they will also work in Tunneli.

Using Tunneli requires a public IP address. Before requesting credentials, find out the public IP address of the network from which the data will be transferred.

The following addresses are not public and therefore cannot be used for data transfers:

  • Addresses starting with:
    • 10.
    • 192.168.
  • Addresses in the range:
    • 172.16.0.0–172.31.255.255
    • 224.0.0.0–239.255.255.255

If you are unsure about your IP address, please contact your organization’s IT support.

How to Use Tunneli

With Tunneli, data controllers can securely deliver extracted datasets, and customers (i.e. permit holders) can submit their own datasets, files, or software to Findata for combining.

In addition, Findata can use Tunneli to deliver combined datasets from multiple data controllers to other secure processing environments. Tunneli can also be used, for example, to transfer personal data from an individual data controller to a secure environment other than Findata’s Kapseli.

See detailed instructions below for different use cases:

Technical Features

Tunneli is used via a web browser and has a file size limit of 4 GB. Larger datasets must be transferred in multiple parts.

Supertunneli

Supertunneli is a secure transfer service implemented through an API interface. It is primarily intended for data controllers of social and healthcare datasets and for service providers of secure processing environments.

Supertunneli Setup Guide

Findata will contact the data sender and/or recipient organization to initiate the Supertunneli connection.

A contract regarding the deployment and use of the Supertunneli is made between Findata and the data controller or service provider of a operating environment (Service User). This contract must be signed by a representative of the Service User, who has the authority to sign on behalf of the organization.

Before signing the contract, the Service User must designate the person(s) responsible for setting up the Supertunneli, a contact person, and provide any additional required information.

Familiarity with REST APIs and S3 object storage formats is beneficial for the setup. Depending on the chosen implementation method, knowledge of installing and managing Python 3 and its libraries may also be useful.

How to Use Supertunneli

The Service User is free to choose how to implement the interface solution. Findata’s service provider, CSC, is responsible for providing technical guidance and, if necessary, reference implementations to facilitate deployment.

Before transmitting any personal data through the established connection, a technical test must be conducted. Once the test is successful, Findata will notify the Service User that the Supertunneli is ready for use.

The Service User is responsible for user management within their own interface and for ensuring that user authentication complies with the requirements of the Act on the Secondary Use of Health and Social Data.

Technical Features

Initially, 1 terabyte (1 TB) of space is allocated for data transfers via the Supertunneli. If the data to be transferred exceeds this limit, the transfer must be agreed upon in advance with Findata.

The data must be encrypted before transmission. The encryption process can be automated by the sender / Service User.

Instructions for controllers on data transfers

Notify the Findata contact person of the persons involved in the data transfer

Findata’s contact person is the sender of the data request.

Provide in your message the following information:

  • Data permit journal number
  • Organisation from which the data will be transferred
  • The person who will receive the potential target group
  • The person who will deliver the extracted data to Findata

Instructions for transferring other data

Complete the data transfer order form

According to the Secondary Use Act, a secure transfer service must be used when transferring personal data. For example, if you need to transfer personal data from an individual data controller to an environment other than Findata’s Kapseli, order the data transfer from Findata. The transfer will be conducted through the Nextcloud transfer service.

  1. Order the data transfer by completing the form below.
  2. Send the completed form to data@findata.fi.

Important notes

  • Only the data controller can order the data transfer.
  • The data controller is responsible for ensuring compliance with the conditions of data permits and amendments for the data being transferred.
  • Both the data provider and recipient must have Nextcloud IDs.
  • Data transfers are subject to a fee. Fees are based on the amount of data transferred and the time required for the transfer.
    • The hourly rate for providing data in accordance with a data permit is determined by the current Decree of Public Charges of the Ministry of Social Affairs.
    • See the current prices in Findata’s price list.
