Shuffle is an open-source platform for security orchestration, automation and response (SOAR). Security teams use its visual editor to build automated workflows that connect different security and IT tools. You can host Shuffle yourself, for example with the bundled Docker Compose configuration, or use the cloud service at shuffler.io. According to the repository, the backend is licensed under AGPL-3.0, while workflows, documentation, apps and the App SDK use the MIT licence.
Shuffle is developed by Shuffle AS, a private limited company in Oslo, Norway. Norway is not an EU member state but belongs to the EEA, and the company is not owned by a foreign parent group. The pages reviewed do not state where the cloud service hosts its data. Organisations that want full control over data and logs can run Shuffle in their own EU environment, so security data does not pass to a third party.
