Cellar runs the operational due diligence you owe your counterparties, so we hold the platform to the same standard. EU data stays in Luxembourg, on ISO/IEC 27001:2022 certified infrastructure, operated by a CSSF-supervised PSF.
Request our security packNo transfer outside the EU. Cellar runs on a Luxembourg private cloud, in sovereign datacenters, operated by a regulated financial-sector professional.
All customer data is hosted in the European Union, in LuxConnect datacenters in Luxembourg. Nothing leaves the Union.
LuxConnect is Luxembourg's state-owned, carrier-neutral datacenter operator, purpose-built for critical and financial workloads.
The platform is run by RCube, a Luxembourg Professional of the Financial Sector, supervised by the CSSF.
The R-Cloud platform is penetration-tested by iTrust, an independent Luxembourg security firm, on a recurring basis.
Business-continuity and disaster-recovery plans are maintained and regularly tested, not just written down.
The hosting operation is covered by internal control and audit reporting, with ongoing monitoring of the platform.
