Privacy and jurisdiction
Cubbit provides European object storage software that encrypts, fragments and replicates information across multiple locations selected for deployment. Direction over where copies reside remains with the deploying organization, which supports data localisation and sovereignty goals. One path places information in partners certified data centres, while the other allows deployment of software defined storage within governed infrastructure. S3 compatibility preserves familiar workflows while geographic distribution strengthens resilience against ransomware events. Controls extend from distributor to end user in multi tenant setups.
