description: 'Cubbit is a European cloud storage provider offering DS3, a sovereign, geo-distributed, S3-compatible object
  storage platform. DS3 encrypts (AES-256), fragments, and replicates data across multiple user-selected locations using Reed-Solomon
  erasure coding, delivering geo-resilience and data sovereignty within Europe. It ships in two forms: DS3 Cloud, a ready-to-use
  managed geo-redundant object store (TBs to PBs), and DS3 Composer, self-hosted software-defined storage you run on your
  own hardware (200 TB+). The storage plane exposes an AWS S3-compatible API at https://s3.cubbit.eu (region eu-west-1), authenticated
  with access key / secret key and AWS Signature Version 4, so existing S3 SDKs, the AWS CLI, rclone, Cyberduck, Veeam and
  other S3 tooling work unchanged. Cubbit is certified to ISO/IEC 27001, 27017, 27018, 9001, 20000-1 and 22301, and is GDPR-
  and NIS2-aligned with Italian ACN PA Cloud qualification.'
