Decentriq, the “Switzerland of data”, is a confidential data collaboration platform. By enforcing compliance and control with advanced privacy technologies, it helps enterprises scale data collaborations across organizational boundaries and unlock value from data that would otherwise be too sensitive to use.

Designed for both data scientists and business users, collaborators use Decentriq’s data clean rooms to analyze sensitive data without sharing it. Powered by confidential computing, data remains encrypted throughout its lifecycle and is verifiably never accessible to another party — not to us, and not even to the cloud provider. Combined with smooth collaboration workflows, fully flexible analysis and maximum interoperability with other technologies, Decentriq makes “sharing without sharing” a scalable strategy.

Decentriq powers data collaboration in the world’s most privacy- and compliance-conscious industries, including media, healthcare, banking, and the public sector.
