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.
